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

Ssh to abacus and become root. Prepare directory

 mkdir /opt/nextmove/smallworld-<version> && cd /opt/nextmove/smallworld-<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 Smallworld For The First Time

Prepare Files and Directories

Ssh to abacus and become root

Open a port in the firewall

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

Go to smallworld databases directory
```
cd /export/db3/
```

Create a Smallworld directory and go to it

mkdir <smallworld_dir> && cd <smallworld_dir>

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

[WebApp]
DepictionUrl=./depict/svg?w=%w&h=%h&smi=%s&qry=%q&cols=%c&cmap=%m

EnabledByDefault=true

SearchTimeOut should be the only option you'll change in the future. It caps search time to lessen strain on machine.

Place any *.anon.maps you've already compiled for testing into the maps sub-directory.

Start Smallworld Instance

Go to smallworld extract directory
```
cd /export/db3/smallworld_extract
```
Create a screen
```
screen -S <screen_name>
```
Export the smallworld directory you've made
```
export SWDIR=/export/db3/<smallworld_dir>
```

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

Hyperlink Results to ZINC20

Open swsearch.js

vim /export/db3/smallworld_extract/.extract/webapps/ROOT/WEB-INF/static/js/swsearch.js

Search this:

?div.append("<b><a target='_blank' href='" + href + "'>" + id + "</a></b>");

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

Open search.html

vim /export/db3/smallworld_extract/.extract/webapps/ROOT/WEB-INF/static/search.html

Search 'Scoring Methods'
```
?Scoring Methods
```

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>

Running SmallWorld from the Command Line

We have been running SmallWorld on n-9-22 as www which uses csh as the default shell. There is a file in /mnt/nfs/soft/www/home/smallworld called run_sw which contains the following commands to set up the SmallWorld Command Line Interface (CLI)

Set the SWDIR environment variable so SmallWorld scripts can access the 12 TB index

   setenv SWDIR /srv/db4

Set the path to the SmallWorld C++ Executables

   set path = ($path /opt/nextmove/bin)

Alias the keyword "sw" to access the Java CLI

   alias sw 'java -jar /opt/nextmove/sw.jar'

Tips for Running SmallWorld on the Command Line

Use sw help to get information about available commands

    sw help
