Search zinc22.py

Description

usage: search_zinc22.py [-h] [--get-vendors]
                        [--configuration-server-url CONFIGURATION_SERVER_URL]
                        zinc_id_in results_out

search for smiles by zinc22 id

positional arguments:
  zinc_id_in            file containing list of zinc ids to look up
  results_out           destination file for output

optional arguments:
  -h, --help            show this help message and exit
  --get-vendors         get vendor supplier codes associated with zinc id
  --configuration-server-url CONFIGURATION_SERVER_URL
                        database containing configuration for zinc22 system

search_zinc22.py is a script for looking up zinc ids on the zinc22 system. The operation is simple- provide a file containing a list of zincids and a destination file to write to. The script will give you a progress bar as it searches the system. If a database is down, the script will let you know and continue gathering the results it can.

The output format is as follows:

SMILES ZINC_ID TRANCHE_NAME

With --get-vendors the output format looks like this:

SMILES ZINC_ID VENDOR_ID TRANCHE_NAME CATALOG

Meaning the script will find all vendor codes and smiles associated with the provided zinc ids.

Location

You can find the script and environment @ /nfs/soft/zinc22/search_zinc on the BKS cluster.

If you get an error along the lines of "ImportError: /lib64/libc.so.6: version `GLIBC_2.14' not found" after sourcing the environment and attempting to run the script, you can try using an alternative environment @ ~xyz/btingle/bin/2dload.testing/py36_psycopg2

If that doesn't work either, you can log into one of our development nodes (ssh user@n-1-17, ssh user@n-1-16, etc.) and run the script there.

Usage w/ Bash on BKS cluster

source /nfs/soft/zinc22/search_zinc/env/bin/activate
python /nfs/soft/zinc22/search_zinc/search_zinc22.py input_zinc_ids.txt output_zinc_ids.txt
python /nfs/soft/zinc22/search_zinc/search_zinc22.py --get-vendors input_zinc_ids.txt output_vendor_ids.txt

Usage w/ Csh on BKS cluster

source /nfs/soft/zinc22/search_zinc/env/bin/activate.csh
python /nfs/soft/zinc22/search_zinc/search_zinc22.py input_zinc_ids.txt output_zinc_ids.txt
python /nfs/soft/zinc22/search_zinc/search_zinc22.py --get-vendors input_zinc_ids.txt output_vendor_ids.txt

Dealing with NULL

Sometimes a ZINC ID will fail to look up. This could be because a server is down (the script will notify you if this is the case), or because the ID is missing from the system for some reason. In this case, it may be helpful to separate the molecules that didn't look up from the molecules that did. You may want to save them for later when the servers come back online, or to run a deeper search with comb_legacy_files.py (more on this below).

How to:

[env]$ cat legitimate_ids.txt > input.txt
[env]$ echo ZINCzz00ZZZZZZZZ >> input.txt
[env]$ echo ZINCyy00AAAAAAAA >> input.txt
[env]$ echo ZINCxx00BBBBBBBB >> input.txt
[env]$ python search_zinc.py input.txt output.txt
Searching Zinc22:  |XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX| 100.0%  0.00s 23/23 complete!
[env]$ grep "_null_" output.txt
_null_ ZINCzz00ZZZZZZZZ H33P270
_null_ ZINCyy00AAAAAAAA H34P280
_null_ ZINCxx00BBBBBBBB H35P290

search_zinc.py will not omit IDs that don't look up from the output, instead it will return the zinc id with "_null_" in every other field. Therefore we can use grep to filter our results.

[env]$ grep "_null_" output.txt > missing.txt
[env]$ grep -v "_null_" output.txt > found.txt

It should be very infrequent that ZINC IDs don't look up, but if this happens you can use the following script:

comb_legacy_files.py

python3 /mnt/nfs/home/xyz/btingle/bin/2dload.testing/utils-2d/tin/misc/comb_legacy_files.py [INPUT_ZINC_IDS_FILE]

You don't need to source any particular python 3 environment for this script, but the environment used for search_zinc22.py will work just fine here.

This script will comb through our deprecated files and attempt to locate your ZINC IDs there. This script will create a file called "result" in your current directory containing all the smiles found.

If after this you're STILL unable to find your zinc ids, you can send them to our development team and we will find them for you.
