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

/nfs/soft2/arthor_configs/ 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:
    • Password: <Ask>
  3. Go to releases. Look for smallworld-java-<version>.tar.gz and copy the link address.
  4. Download using wget
     wget --user --password <Ask> <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.

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
  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 -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/ at the directory where you stored the smiles.

Here is the content of the script:



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

for j in $target
        echo 'smi2atdb -v -r -j '$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

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

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

  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]
  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
  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>
