fragments

i have fragments categorized per functional group in the folder fragments

fragcombine

the main script, heres an example usage

python3 fragcombine.py --i example_data/c_abl1_dock.sdf example_data/a_abl1_dock.sdf --angle_cutoff 0.85 --coord_cutoff 0.5 --output example_data/abl1_dock_merged.sdf

here's the result, 76/1000000 are hits, in the gif below the combined fragments are sshown in cyan:

dock frags

this is just a handy script for running dockstring jobs. the example data in example_data was generated using

python3 dock_frags.py --input fragments/c_1000.csv --target ABL1 --output example_data/c_abl1_dock.sdf
python3 dock_frags.py --input fragments/a_1000.csv --target ABL1 --output example_data/a_abl1_dock.sdf

pharmacophore embed

provide a pharmacophore as an csv file of the form feature,x,y,z,radius, one line one feature. for example:

Acceptor,2.275,0.0,0.0,1
Donor,-2.275,0.0,0.0,1
Aromatic,0.0,2.275,2,3.85,0.8
Acceptor,0.0,-2.275,3.85,1

embed fragment using

python3 pharmacophore_embed.py --input fragments/a_1000.csv --pharmacophore example_data/ph2.csv --retained_features 1 2 --output example_data/ph4_a_1000.sdf
python3 pharmacophore_embed.py --input fragments/a_1000.csv --pharmacophore example_data/ph2.csv --retained_features 3 4 --output example_data/ph4_a_1000.sdf
