==Install and Set Up on TomCat (Method 1)==
+
Arthor configurations and the frontend files are consolidated in '''/nfs/soft2/arthor_configs/'''.
Arthor ran on n-1-136, which runs CentOS Linux release 7.7.1908 (Core).  You can check the version of CentOS with the following command
 
    cat /etc/centos-release
 
  
Check your current version of Java with the following command:
+
'''/nfs/soft2/arthor_configs/start_arthor_script.sh''' can start/restart Arthor instances on respective machines.
    java -version
 
  
On n-1-136 we are running openjdk version "1.8.0_222", OpenJDK Runtime Environment (build 1.8.0_222-b10), and OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
+
Launch the script to see the options available.
If Java is not installed, install it using yum

==Open port for Arthor==
+
== How To Launch Arthor For The First Time ==
In order for Arthor to be usable in the browser, the port you wish to run it on must be opened.
+
=== Prepare Files and Directories ===
https://www.thegeekdiary.com/how-to-open-a-ports-in-centos-rhel-7/
+
# Ssh to nfs-exc and become root
 
+
# Open a port in the firewall
===Step 1: Check Port Status===
+
#: <source>firewall-cmd --permanent --add-port=<port_number>/tcp  
Check that the port is not open and that Apache is not showing that port.
+
firewall-cmd --reload
    netstat -na | grep <port number you are checking>
+
</source>
 
+
# Go to Arthor Config directory
    lsof -i -P |grep http
+
#: <source>cd /export/soft2/arthor_configs/arthor-<latest_version></source>
 
+
# Create an Arthor config file
===Step 2: Check Port Status in IP Tables===
+
#: <source>vim <name_of_file>.cfg</source>
    iptables-save | grep <port number you are checking>
+
#* Add these lines in the file. Check the manual for more options.
 
+
#: <source>
I skipped Step 3 from the guide, because there was a lot of information in the /etc/services file and I didn't want to edit it and break something.
+
DataDir=/local2/public_arthor

MaxConcurrentSearches=6
===Step 4: Open Firewall Ports===
+
MaxThreadsPerSearch=8
I did not include the zone=public section because the stand-alone servers are usually used for private instances of Arthor and SmallWorld.

=== Start Arthor Instance ===
 
+
# Now ssh into a machine you wish to run an Arthor instance on and become root
===Step 5: Check that port is working===

==How to run standalone Arthor instance==
+
#: <source>java -jar /nfs/soft2/arthor_configs/arthor-<version>/arthor-<version>-centos7/java/arthor.jar --httpPort=<port_number></source>
 
 
===Step 1: Use or start a bash shell===
 
You can check your default shell using
 
    echo $SHELL
 
 
 
If your default shell is csh, use
 
    bash
 
to start a new bash shell in the current terminal window. Note that echo $SHELL will show you your default shell regardless of the current shell.
 
 
 
===Step 2: Set your environment variables===
 
    export ARTHOR_DIR=/opt/nextmove/arthor/arthor-3.3-centos7
 
    export PATH=$ARTHOR_DIR/bin/:$PATH
 
 
 
Make sure the ARTHOR_DIR variable is set to the directory for the latest version of Arthor or whichever version you would like to test.
 
The PATH environment variable is needed if you wish to use the Arthor tools from the command line
 
 
 
===Step 3: Run the arthor-server.jar===
 
    java -jar /opt/nextmove/arthor/arthor-3.3-centos7/java/arthor.jar --httpPort <your httpPort>
 
 
 
==Setting environment variables for an Arthor Server==
 
Set the environment variables in the setenv.sh file.  Note: Be sure to edit the file in the directory corresponding to the latest version of TomCat.  As of December 2019, we are running 9.0.27 on n-1-136.
 
 
 
  vim  /opt/tomcat/apache-tomcat-9.0.27/bin/setenv.sh
 
 
 
Add the line below to the setenv.sh file above, or substitute the path to wherever you currently store the arthor.cfg file
 
  export ARTHOR_CONFIG=/usr/local/tomcat/arthor.cfg
 
 
 
Here is an example of the arthor.cfg file:
 
  BinDir=/opt/nextmove/arthor/arthor-3.3-centos7/bin
 
  DataDir=/local2/arthor_local_8081/

==Background==
 
Before working with Arthor, it is recommended that you familiarize yourself with the Arthor documentation. Some useful pages to look at include 3-5, 22-25 and 33-39. Of course, reading everything would be the best!
 
  
==Checking Disk Space Usage==

== How to Build Arthor Databases==
Before building arthor indexes, it's always a good thing to check what percent of the memory is being used. Try to be cautious with how much memory you have left, and make sure to check while building indexes to make sure that you have enough space. To check, run the following command:
+
We can build Arthor Databases anywhere. Consolidate smiles into one directory so you can index them all one by one.
  
  df -h /<directory with disc>
+
Just use the script located at '''/nfs/home/jjg/scripts/arthor_index_script.sh''' at the directory where you c
  
==Building Large Databases==
+
Here is the content of the script:
At the moment, we are building databases of size 500M molecules by merging smile files. There are multiple methods of trying to create large databases, one being merging based off of the same H?? prefix and stopping once the database reaches > 500M molecules (or whatever upperbound you want to use). Here is some python code that simulates this merging process. Essentially the program takes all of the .smi files within an input directory, sorts them lexiographically, and begins merging these .smi files together in order until the size reaches > 500M molecules.

#!/bin/bash

==Building Arthor Indexes==
+
version="3.4.2"
Once you've merged the .smi files together, it's time to start building the databases themselves. To do this we use the command
 
  
  smi2atdb -j 0 -p <The .smi file> <The .atdb>
+
export ARTHOR_DIR=/nfs/soft2/arthor_configs/arthor-$version/arthor-$version-centos7/
 +
export PATH=$ARTHOR_DIR/bin/:$PATH
  
The flag "-j 0" enables parallel generation and utilizes all available processors to generate the .atdb file. The "-p" flag stores the offset position in the ATDB file. Since we're building indexes for the Web Application, you must use the "-p" flag when building indexes. Please note that the name of the .smi file should also be the name of the .atdb file. That way, the Web Application knows to use these files together and correctly display the required images. Refer to pages 33-34 in the Arthor documentation for more information.
+
target="*.smi"
  
If there are too many large .smi files and you do not want to manually build each .atdb file, you can use this python script which takes all of the .smi files in the current directory and converts them to .atdb files. Make sure to modify mypath to the directory containing the .smi files. You can change the variable "create_fp" to false if you don't want to create .atdb.fp files (refer to page 9 in the Arthor documentation).
+
for j in $target
 +
do
 +
        echo 'smi2atdb -j 4 -p '$j' '${j}'.atdb'
 +
        smi2atdb -j 4 -p $j ${j}.atdb
 +
        echo 'atdb2fp -j 4 '$j'.atdb'
 +
atdb2fp -j 4 ${j}.atdb
 +
done
 +
</source>

  from os.path import isfile, join
 
 
 
  mypath = "<Path containing the .smi files"
 
  onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]
 
 
 
  create_fp = True
 
 
 
  for file in onlyfiles:
 
      arr = file.split(".")
 
 
 
      if (arr[len(arr) - 1] == "smi"):
 
        process = subprocess.Popen("/nfs/ex9/work/xyz/psql/arthor-3.3-centos7/bin/smi2atdb -j 0 -p {0} {1}.atdb".format(join(mypath, file), arr[0]), shell=True)
 
        process.wait()
 
 
 
        print("SUCCESS! {0}.atdb file was created!".format(arr[0]))
 
 
 
        if (create_fp):
 
            process = subprocess.Popen("/nfs/ex9/work/xyz/psql/arthor-3.3-centos7/bin/atdb2fp -j 0 {0}.atdb".format(arr[0]), shell=True)
 
            process.wait()
 
     
 
            print("SUCCESS! {0}.atdb.fp file was created!".format(arr[0]))
 
 
 
==Uploading Indexes to the Web Application==
 
One can upload indexes to the Web Application by changing the "DATADIR" variable in the arthor.cfg file to the directory holding the .atdb files. This is already set up on n-1-136 and n-5-34.
 
 
 
==Virtual Memory==
 
In addition to modifying the arthor.cfg file, virtual memory can also be used to make queries faster. There can still be More information can be found in pages 10-16 in the Arthor Documentation.
 
  
 
==Setting up Round Table==
 
==Setting up Round Table==
This is a new feature in Arthor 3.0 and is currently beta (January 2020). See section 2.4 in the manual
+
"Round Table allows you to serve and split chemical searches across multiple host machines.  The implementation provides a lightweight proxy that forwards requests to other Arthor host servers that do the actual search.  Communication is done using the existing Web APIs.
As explained in the manual, "Round Table allows you to serve and split chemical searches across multiple host machines.  The implementation provides a lightweight proxy that forwards requests to other Arthor host servers that do the actual search.  Communication is done using the existing Web APIs.
 
 
 
Since Arthor requires CentOS 7, as of January 2020 we have 6 servers that are capable of running Arthor with Round Table.
 
 
 
 
===Setting up Host Server===
 
===Setting up Host Server===
If we want to add machines to the Round Table, for example 'nun' and 'samekh', we need to edit their arthor.cfg file so that when our Local Machine passes commands these secondary servers know to perform the search they are given.
+
# Ssh to nfs-soft2 and become root
 
+
# Open a port in the firewall
  $ cat arthor.cfg
+
#: <source>firewall-cmd --permanent --add-port=<port_number>/tcp
  MaxThreadsPerSearch=4
+
firewall-cmd --reload
  AutomaticIndex=false
+
</source>
  DATADIR=<Directory where smiles are located>
+
# Go to Arthor Config Directory
 
+
#: <source>cd /export/soft2/arthor_configs/arthor-<version></source>
We then run the jar server on each of these host machines containing data on any available port.
+
# Create Round Table Head configuration file. Here is an example:
 
+
# <source>
  java -jar /nfs/ex9/work/xyz/psql/arthor-3.3-centos7/java/arthor.jar --httpPort <port>
+
[RoundTable]
 
+
RemoteClient=http://10.20.0.41:8008
For our local machine, the arthor.cfg file will look different.
+
RemoteClient=http://10.20.5.19:8008
 
+
Resolver=https://sw.docking.org/util/smi2mol?smi=%s
  $ cat arthor.cfg
+
</source>
  [RoundTable]  
+
# Now ssh into a machine you wish to run the round table head on and become root
  RemoteClient=http://skynet:<port number where jar server is running>/
+
# Change your shell to bash if you havn't already
  RemoteClient=http://hal:<port number where jar server is running>/
+
#: <source>bash</source>
 
+
# Create a screen
Please refer to Section 2 in the RoundTable Documentation file (pages 6-8) for more useful information on configuration.
+
#: <source>screen -S <screen_name></source>
 
+
# Prepare Arthor Config Path
Then run the following command on n-1-136:
+
#: <source>export ARTHOR_CONFIG="/nfs/soft2/arthor_configs/arthor-<version>/<round_table_head>.cfg"</source>
+
# Launch java
  java -jar /nfs/ex9/work/xyz/psql/arthor-3.3-centos7/java/arthor.jar --httpPort <port>
+
#: <source>java -jar /nfs/soft2/arthor_configs/arthor-<version>/arthor-<version>-centos7/java/arthor.jar --httpPort=<port_number></source>

Introduction

Here is the link to Arthor's manual

  • Username: ucsf@nextmovesoftware.com
  • Password: <Ask jjiteam@googlegroups.com>

Arthor configurations and the frontend files are consolidated in /nfs/soft2/arthor_configs/.

/nfs/soft2/arthor_configs/start_arthor_script.sh can start/restart Arthor instances on respective machines.

Launch the script to see the options available.

How To Download Arthor

  1. Ssh to nfs-soft2 and become root. Prepare directory
     mkdir /export/soft2/arthor_configs/arthor-<version> && cd /export/soft2/arthor_configs/arthor-<version>
  2. Download Software with this link
    • Username: ucsf@nextmovesoftware.com
    • Password: <Ask jjiteam@googlegroups.com>
  3. Go to releases. Look for smallworld-java-<version>.tar.gz and copy the link address.
  4. Download using wget
     wget --user ucsf@nextmovesoftware.com --password <Ask jjiteam@googlegroups.com> <link address>
  5. Decompress the file
    •  tar -xvf <file_name>

How To Launch Arthor For The First Time

Prepare Files and Directories

  1. Ssh to nfs-exc and become root
  2. Open a port in the firewall
    firewall-cmd --permanent --add-port=<port_number>/tcp 
    firewall-cmd --reload
  3. Go to Arthor Config directory
    cd /export/soft2/arthor_configs/arthor-<latest_version>
  4. Create an Arthor config file
    vim <name_of_file>.cfg
    • Add these lines in the file. Check the manual for more options.
    DataDir=/local2/public_arthor
    MaxConcurrentSearches=6
    MaxThreadsPerSearch=8
    AutomaticIndex=false
    AsyncHitCountMax=20000
    Depiction=./depict/bot/svg?w=%w&h=%h&svgunits=px&smi=%s&zoom=0.8&sma=%m&smalim=1
    Resolver=https://sw.docking.org/util/smi2mol?smi=%s

Start Arthor Instance

  1. Now ssh into a machine you wish to run an Arthor instance on and become root
  2. Change your shell to bash if you havn't already
    bash
  3. Create a screen
    screen -S <screen_name>
  4. Prepare Arthor Config Path
    export ARTHOR_CONFIG="/nfs/soft2/arthor_configs/arthor-<version>/<name_of_config_file>.cfg"
  5. Launch java
    java -jar /nfs/soft2/arthor_configs/arthor-<version>/arthor-<version>-centos7/java/arthor.jar --httpPort=<port_number>

Configuration Details

  • DataDir: This is the directory where the Arthor data files live. Location where the index files will be created and loaded from.
  • MaxConcurrentSearches: Controls the maximum number of searches that can be run concurrently by setting the database pool size. When switching between a large number of databases it can be useful to have a larger pool size, the only trade off is keeping file pointers open.
  • MaxThreadsPerSearch: The number of threads to use for both ATDB and ATFP searches
  • Set AutomaticIndex to false if you don't want new smiles files added to the data directory to be indexed automatically
  • AsyncHitCountMax: The upper-bound for the number of hits to retrieve in background searches.
  • Resolver: Using Smallworld API, allows input box to take in a SMILE format and automatically draw on the board.

Check Arthor manual for more configuration options

How to Build Arthor Databases

We can build Arthor Databases anywhere. Consolidate smiles into one directory so you can index them all one by one.

Just use the script located at /nfs/home/jjg/scripts/arthor_index_script.sh at the directory where you c

Here is the content of the script:

#!/bin/bash

version="3.4.2"

export ARTHOR_DIR=/nfs/soft2/arthor_configs/arthor-$version/arthor-$version-centos7/
export PATH=$ARTHOR_DIR/bin/:$PATH

target="*.smi"

for j in $target
do
        echo 'smi2atdb -j 4 -p '$j' '${j}'.atdb'
        smi2atdb -j 4 -p $j ${j}.atdb
        echo 'atdb2fp -j 4 '$j'.atdb'
	atdb2fp -j 4 ${j}.atdb
done

Command Details

smi2atdb creates the atdb files needed for Substructure searching.

  • -j is the amount of threads to use to index the smiles file
  • -p stores the position of the original file

atdb2fp makes substructure searching faster

Setting up Round Table

"Round Table allows you to serve and split chemical searches across multiple host machines. The implementation provides a lightweight proxy that forwards requests to other Arthor host servers that do the actual search. Communication is done using the existing Web APIs.

Setting up Host Server

  1. Ssh to nfs-soft2 and become root
  2. Open a port in the firewall
    firewall-cmd --permanent --add-port=<port_number>/tcp 
    firewall-cmd --reload
  3. Go to Arthor Config Directory
    cd /export/soft2/arthor_configs/arthor-<version>
  4. Create Round Table Head configuration file. Here is an example:
  5. [RoundTable]
    RemoteClient=http://10.20.0.41:8008
    RemoteClient=http://10.20.5.19:8008
    Resolver=https://sw.docking.org/util/smi2mol?smi=%s
  6. Now ssh into a machine you wish to run the round table head on and become root
  7. Change your shell to bash if you havn't already
    bash
  8. Create a screen
    screen -S <screen_name>
  9. Prepare Arthor Config Path
    export ARTHOR_CONFIG="/nfs/soft2/arthor_configs/arthor-<version>/<round_table_head>.cfg"
  10. Launch java
    java -jar /nfs/soft2/arthor_configs/arthor-<version>/arthor-<version>-centos7/java/arthor.jar --httpPort=<port_number>

Customizing Arthor Frontend to our needs

The frontend Arthor code is located at /nfs/exc/arthor_configs/* and the * is based on current running version.

Add Arthor Download Options

For Arthor 3.4:

1. vim .extract/webapps/ROOT/WEB-INF/static/index.html

2. search: arthor_tsv_link

3. in the div with the class=”dropdown-content”, add these link options and change the number accordingly:

              <a id="arthor_tsv_link" href="#"> TSV-500</a>
              <a id="arthor_tsv_link_5000" href="#"> TSV-5,000</a>
              <a id="arthor_tsv_link_50000" href="#"> TSV-50,000</a>
              <a id="arthor_tsv_link_100000" href="#"> TSV-100,000</a>
              <a id="arthor_tsv_link_max" href="#"> TSV-max</a>
              <a id="arthor_csv_link" href="#"> CSV-500</a>
              <a id="arthor_csv_link_5000" href="#"> CSV-5,000</a>
              <a id="arthor_csv_link_50000" href="#"> CSV-50,000</a>
              <a id="arthor_csv_link_100000" href="#"> CSV-100,000</a>
              <a id="arthor_csv_link_max" href="#"> CSV-max</a>
              <a id="arthor_sdf_link" href="#"> SDF-500</a>
              <a id="arthor_sdf_link_5000" href="#"> SDF-5,000</a>
              <a id="arthor_sdf_link_50000" href="#"> SDF-50,000</a>
              <a id="arthor_sdf_link_100000" href="#"> SDF-100,000</a>
              <a id="arthor_sdf_link_max" href="#"> SDF-max</a>

4. then vim .extract/webapps/ROOT/WEB-INF/static/js/index.js

5. search: function $(t){

6. in the function $(t), add these lines:

if(document.getElementById("arthor_tsv_link")) {
       var e=i.a.param({query:s.b.query,type:s.b.type,draw:0,start:0,length:t,flags:s.b.flags}),n=s.b.url+"/dt/"+E(s.b.table)+"/search";i()("#arthor_sdf_link").attr("href",n+".sdf?"+e),i() ("#arthor_tsv_link").attr("href",n+".tsv?"+e),i()("#arthor_csv_link").attr("href",n+".csv?"+e)
}
if (document.getElementById("arthor_tsv_link_5000")) {
       var e=i.a.param({query:s.b.query,type:s.b.type,draw:0,start:0,length:5000,flags:s.b.flags}),n=s.b.url+"/dt/"+E(s.b.table)+"/search";i()("#arthor_sdf_link_5000").attr("href",n+".sdf?"+e),i()("#arthor_tsv_link_5000").attr("href",n+".tsv?"+e),i()("#arthor_csv_link_5000").attr("href",n+".csv?"+e)
}
if (document.getElementById("arthor_tsv_link_50000")) {
       var e=i.a.param({query:s.b.query,type:s.b.type,draw:0,start:0,length:50000,flags:s.b.flags}),n=s.b.url+"/dt/"+E(s.b.table)+"/search";i()("#arthor_sdf_link_50000").attr("href",n+".sdf?"+e),i()("#arthor_tsv_link_50000").attr("href",n+".tsv?"+e),i()("#arthor_csv_link_50000").attr("href",n+".csv?"+e)
}
if (document.getElementById("arthor_tsv_link_100000")) {
       var e=i.a.param({query:s.b.query,type:s.b.type,draw:0,start:0,length:100000,flags:s.b.flags}),n=s.b.url+"/dt/"+E(s.b.table)+"/search";i()("#arthor_sdf_link_100000").attr("href",n+".sdf?"+e),i()("#arthor_tsv_link_100000").attr("href",n+".tsv?"+e),i()("#arthor_csv_link_100000").attr("href",n+".csv?"+e)
}
if (document.getElementById("arthor_tsv_link_max")) {
       var e=i.a.param({query:s.b.query,type:s.b.type,draw:0,start:0,length:1000000000,flags:s.b.flags}),n=s.b.url+"/dt/"+E(s.b.table)+"/search";i()("#arthor_sdf_link_max").attr("href",n+".sdf?"+e),i()("#arthor_tsv_link_max").attr("href",n+".tsv?"+e),i()("#arthor_csv_link_max").attr("href",n+".csv?"+e)
}

Take out Similarity Button

vim .extract/webapps/ROOT/WEB-INF/static/index.html
search: Similarity

Comment out this line < li value="Similarity" onclick="setSearchType(this)" class="first"> Similarity //added spaces at the beginning and end so prevent wiki from converting it Then add "first" in Substructure's class

Hyperlink to zinc20

vim .extract/webapps/ROOT/WEB-INF/static/js/index.js
search: table_name
*find this line "< b>" + d + "< /b>"
*replace with "< b><a target='_blank' href='https://zinc20.docking.org/substances/"+d+"'>" + d + "</a>" //added spaces at the beginning and end so prevent wiki from converting it

Make Input Box Work

At the end of the Arthor config file add this:
   Resolver=https://sw.docking.org/util/smi2mol?smi=%s
To copy smiles in the input box:
   vim .extract/webapps/ROOT/WEB-INF/static/js/index.js
   search this: “var e=t.src.smiles()”
   add this after the semi-colon
       document.getElementById("ar_text_input").value = e;
