All smallworld databases live in abacus' db3.

Smallworld frontend files are consolidated and located at /export/db3/smallworld_extract/.extract.

Execute command start_smallworld to see options on which smallworld instance to start/restart.

How to Download Smallworld

  1. Ssh to abacus and become root. Prepare directory 
     mkdir /opt/nextmove/smallworld-<version> && cd /opt/nextmove/smallworld-<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 Smallworld For The First Time

Prepare Files and Directories

  1. Ssh to abacus and become root
  2. Open a port in the firewall 
    firewall-cmd --permanent --add-port=<port_number>/tcp 
firewall-cmd --reload
  3. Go to smallworld databases directory 
    cd /export/db3/
  4. Create a Smallworld directory and go to it 
    mkdir <smallworld_dir> && cd <smallworld_dir>
  5. Inside that directory, create these
    • a symbolic link to the smallworld anon map
    ln -s /export/db2/smallworld_anon_21Q4 anon
    • a sub-directory called maps to store databases
    mkdir maps
    • a smallworld config file
    vim smallworld.cfg
    • Add this block of code inside the config file

    • SearchTimeOut should be the only option you'll change in the future. It caps search time to lessen strain on machine.
  6. Place any *.anon.maps you've already compiled for testing into the maps sub-directory.

Start Smallworld Instance

  1. Go to smallworld extract directory 
    cd /export/db3/smallworld_extract
  2. Create a screen 
    screen -S <screen_name>
  3. Export the smallworld directory you've made 
    export SWDIR=/export/db3/<smallworld_dir>
  4. Launch java 
    java -jar /opt/nextmove/smallworld-<version>/sw-ws-<version>.jar --httpPort=<port_number>

How to Build Smallworld Maps/Databases

Consolidate smiles into /export/db3/temp_mapping.

Use the script located in that directory called smallworld_map_script.

Here is the content of the script: 

#!/bin/csh -f
setenv SWDIR /export/db3/public_smallworld_4th_gen/

alias sw 'time java -jar /opt/nextmove/smallworld-5.1/sw.jar'

set target = '*.smi'

foreach i ($target)
	echo '(sw map' $i '-T tmp/ -o '${i}'.anon.map -u '${i}'.anon.unmapped) |& tee '${i}'_log'
	(sw map $i -T tmp/ -o ${i}.anon.map -u ${i}.anon.unmapped) |& tee ${i}_log
	echo 'sw blm -p 0.01 '${i}'.anon.map'
	sw blm -p 0.01 ${i}.anon.map
end

Command Details

setenv sets the environment where the anon master map is

java -jar /opt/nextmove/smallworld-5.1/sw.jar shortened to sw via alias

map will map the smiles based on the current anon master map.

  • -T stores temp files so /tmp does not get overloaded
  • -o output with custom name you like
  • -u will collect the unmapped molecules to send to Nextmove or to use swextend

tee will log the progress of the process

Splitting Databases

[Follow this page if John has asked you to split the database into smaller slices.]

Customize Smallworld FrontEnd To Our Needs (Smallworld 5.5)

These instructions only worked and compiled for me in the machine called epyc which is running Rocky 8 Linux operating system.

Summary of changes in swsearch.js:

  • Conditional hyperlinks attached to smallworld hits. Leads to zinc20, cartblanche22, or nothing.

Summary of changes in search.html:

  • Add 'Ask Questions' and contact info

Install Prerequisite Packages

  1. Install Apache Maven 
    • dnf install maven -y
  2. In your home directory, create a new directory to hold the files for the upcoming procedures 
    • mkdir /mnt/nfs/home/jjg/smallworld_build_from_source
  3. Download these latest Smallworlds and store them in 'smallworld_build_from_source/'. Here's how to download Smallworld.
    • arthor-3.4.7-source.tar.gz
    • arthor-3.4.7-centos7.tar.gz
  4. Extract contents from the tar.gz files 
    • tar -xvf arthor-3.4.7-source.tar.gz
tar -xvf arthor-3.4.7-centos7.tar.gz
  5. Install Apache Maven Arthor dependencies through this script

Hyperlink Results to ZINC20

  1. Open swsearch.js 
    vim /export/db3/smallworld_extract/.extract/webapps/ROOT/WEB-INF/static/js/swsearch.js
  2. Search this: 
    ?div.append("<b><a target='_blank' href='" + href + "'>" + id + "</a></b>");
  3. On the else statement replace the line with this 
    div.append("<b><a target='_blank' href='https://zinc20.docking.org/substances/"+id+"'>" + id + "</a></b>");

Add 'Ask Questions' On Smallworld

  1. Open search.html 
    vim /export/db3/smallworld_extract/.extract/webapps/ROOT/WEB-INF/static/search.html
  2. Search 'Scoring Methods' 
    ?Scoring Methods
  3. At the end of that big block of 'div', add this: 
    <div class="section-head">
        Ask Questions
        <table class="swopt searchasyoudraw" style="width: 100%">
                <th style="text-align: left">Email us: jjiteam@googlegroups.com</th>
        </table>
</div>

Restarting Smallworld Instance(s)

  1. Ssh to abacus and become root
  2. execute run_sw_on_reboot.sh to show restart all instances on the machine 
    bash /root/run_arthors_on_reboot.sh
  3. execute start_smallworld to restart specific Smallworld instance. It will show you options to choose from. 
    start_smallworld
