1) cluster about 1M molecules
Run the script at where your extract_all.sort.uniq.txt locates
cd where your extract_all.sort.uniq.txt locates csh ~jklyu/zzz.script/large_scale_docking/cluster_analysis/best_first_clustering.csh number_of_top_molecules_you_want_to_cluster TC_cutoff
Example:
csh ~jklyu/zzz.script/large_scale_docking/cluster_analysis/best_first_clustering.csh 1000000 0.5
so you will cluster top1M molecules from a docking run with tc cutoff 0.5.
For clustering top1M molecules, it usually takes about 6 hours. Please do not cluster more than 1M molecules by this script.
2) cluster more than 1M molecules
Follow the tutorial Large-scale SMILES Requesting and Fingerprints Converting to get the smi files and compressed fingerprints for the molecules you want to cluster
Then run the command below
setenv BFCPATH "/mnt/nfs/home/jklyu/zzz.github/ChemInfTools/utils/best_first_clustering_uint16" ${BFCPATH}/best_first_clustering_uint16 /path/fingerprint.file /path/count.file /path/smiles.file tc.thres.val max.num.val
syntax: best_first_clustering_uint16 (1) fingerprint file (2) count file (3) smiles file (4) tanimoto coefficient threshold value to define clustering (must be between 0.0 and 1.0) (5) max number of clusters (must be an integer)
