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

Ssh to nfs-soft2 and become root. Prepare directory

 mkdir /export/soft2/arthor_configs/arthor-<version> && cd /export/soft2/arthor_configs/arthor-<version>

Download Software with this link
- Username: ucsf@nextmovesoftware.com
- Password: <Ask jjiteam@googlegroups.com>
Go to releases. Look for smallworld-java-<version>.tar.gz and copy the link address.

Download using wget

 wget --user ucsf@nextmovesoftware.com --password <Ask jjiteam@googlegroups.com> <link address>

Decompress the file
- ```
 tar -xvf <file_name>
```

How To Launch Arthor For The First Time

Prepare Files and Directories

Ssh to nfs-exc and become root

Open a port in the firewall

firewall-cmd --permanent --add-port=<port_number>/tcp 
firewall-cmd --reload

Go to Arthor Config directory

cd /export/soft2/arthor_configs/arthor-<latest_version>

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

Now ssh into a machine you wish to run an Arthor instance on and become root
Change your shell to bash if you havn't already
```
bash
```
Create a screen
```
screen -S <screen_name>
```

Prepare Arthor Config Path

export ARTHOR_CONFIG="/nfs/soft2/arthor_configs/arthor-<version>/<name_of_config_file>.cfg"

Launch java

java -jar -Dserver.port=<port_number> /nfs/soft2/arthor_configs/arthor-<version>/arthor-server-<version>.war

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 stored the smiles.

Here is the content of the script:

#!/bin/bash

target="*.smi"
threads='48'
version="3.6.1"


export ARTHOR_DIR=/nfs/soft2/arthor_configs/arthor-$version/arthor-$version-centos8/
export PATH=$ARTHOR_DIR/bin/:$PATH

for j in $target
do
        echo 'smi2atdb -v -r -j '$threads' -p '$j' '${j}'.atdb |& tee -a '${j}'_log'
        time smi2atdb -v -r -j $threads -p $j ${j}.atdb |& tee -a ${j}_log
	echo 'smi2atfp -j '$threads' -p '$j' '${j}.atfp' |& tee -a '${j}'_log'
        time smi2atfp -j $threads -p $j ${j}.atfp |& tee -a ${j}_log
done

for i in $target*atdb
do
	echo 'atdb2fp -j '$threads' '$i
        time atdb2fp -j $threads $i
	chmod 744 $i.fp
done

Command Details

smi2atdb creates the atdb files needed for Substructure searching.

-v verbose
-r Compute and store ring size information in the index allowing ring size (3-10) expressions ([r6] and [Z5])
-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

smi2atfp creates atfp files for similarity searching

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

Ssh to nfs-soft2 and become root

Open a port in the firewall

firewall-cmd --permanent --add-port=<port_number>/tcp 
firewall-cmd --reload

Go to Arthor Config Directory

cd /export/soft2/arthor_configs/arthor-<version>

Create Round Table Head configuration file. Here is an example:

[RoundTable]
RemoteClient=http://10.20.0.41:8008
RemoteClient=http://10.20.5.19:8008
Resolver=https://sw.docking.org/util/smi2mol?smi=%s

Now ssh into a machine you wish to run the round table head on and become root
Change your shell to bash if you havn't already
```
bash
```
Create a screen
```
screen -S <screen_name>
```

Prepare Arthor Config Path

export ARTHOR_CONFIG="/nfs/soft2/arthor_configs/arthor-<version>/<round_table_head>.cfg"

Launch java

java -jar /nfs/soft2/arthor_configs/arthor-<version>/arthor-<version>-centos7/java/arthor.jar --httpPort=<port_number>

Compile/Minify Code through NPM

Install NPM packages and Minify Code

cd /nfs/home/jjg/arthor_build_from_source/arthor-3.6.1/arthor-3.6.1-source/server-ui
npm install
npx webpack-dev-server
npx webpack --mode=production

If the npx commands don't work, try updating node and npm version to the latest one.

Build the war file

cd /nfs/home/jjg/arthor_build_from_source/arthor-3.6.1/arthor-3.6.1-source/server
mvn install -Pbootable

If it works, then the path to new war file is at /mnt/nfs/home/jjg/arthor_build_from_source/arthor-3.4.7/arthor-3.4.7-source/server/target/arthor-server-3.4.7.war

Adding Arthor to Systemd (example)

Create service files

touch /etc/systemd/system/arthor.service

Add this code block in the service file

[Unit]
Description=Arthor Public Instance
After=network.target

[Service]
Type=exec
Restart=always
RestartSec=3
User=root
ExecStart=/usr/bin/bash /nfs/soft2/arthor_configs/start_arthor_service.sh -public
ExecStop=/bin/kill -15 $MAINPID

[Install]
WantedBy=multi-user.target

Change "ExecStart" to other Arthor Instances

Restarting Arthor Instance(s) Instructions

Public and Private Arthor

ssh to "arthor" server and run

systemctl <start|stop|restart> <arthor|arthorp>

ArthorBB, ArthorCC, and ArthorCovalent

ssh to "epyc-a40" server and run

systemctl <start|stop|restart> <arthorbb|arthorcc|arthorcovalent>

Super Private Arthor

Ssh to machine with respective Arthor instance and become root
execute run_arthors_on_reboot.sh to show restart all instances on the machine
```
bash /root/run_arthors_on_reboot.sh
```
execute start_arthor_script.sh to restart specific Arthor instance. It will show you options to choose from.
```
bash /nfs/soft2/arthor_configs/start_arthor_script.sh
```
