− | ===Fragment Libraries===
| |
− | For this experiment a general fragment library to account for all the possible ligands the GA can produce. A focused Fragment library will not be enough to account for all the possibilities since it is too small of a set of data.
| |
− | | |
− | The first step for this experiment is to generate a directory to perform the work in
| |
− | mkdir 2NNQ_GA
| |
− | Go into this new directory and then create another directory that will store all the fragment molecules
| |
− | mkdir fraglib
| |
− | Enter the file directory fraglib
| |
− | cd fraglib
| |
− | Create a new file called 2NNQ.fraglib
| |
− | touch 2NNQ.fraglib
| |
− | dock6 -i 2NNQ.fraglib
| |
− | Answer the following prompts using these responses
| |
− | conformer_search_type flex
| |
− | write_fragment_libraries yes
| |
− | fragment_library_prefix 2NNQ.fraglib
| |
− | fragment_library_freq_cutoff 1
| |
− | fragment_library_sort_method freq
| |
− | fragment_library_trans_origin no
| |
− | use_internal_energy no
| |
− | ligand_atom_file ../../2NNQ_Tutorial/1.dockprep/2nnq_lig_withH.mol2
| |
− | limit_max_ligands no
| |
− | skip_molecule no
| |
− | read_mol_solvation no
| |
− | calculate_rmsd no
| |
− | use_database_filter no
| |
− | orient_ligand no
| |
− | bump_filter no
| |
− | score_molecules no
| |
− | atom_model all
| |
− | vdw_defn_file /gpfs/projects/AMS536/zzz.programs/dock6/parameters/vdw_AMBER_parm99.defn

| |
− | flex_drive_file /gpfs/projects/AMS536/zzz.programs/dock6/parameters/flex_drive.tbl
| |
− | ligand_outfile_prefix 2NNQ_frag_output
| |
− | write_orientations no
| |
− | num_scored_conformers 1
| |
− | rank_ligands no
| |
− | | |
− | The only aspect that is relevant of this fragment library generated is the torsion environment that should be titled 2NNQ.fraglib_torenv.dat
| |
− | Following this step the torsion environments of this molecule will be combined with the file titled full_sorted_fraglib.dat using the python software combine_torenv.py
| |
− | py /gpfs/projects/rizzo/zzz.programs/torsion_env_combination/combine_torenv.py 2NNQ.fraglib_torenv.dat /gpfs/projects/rizzo/zzz.programs/dock6.10_2019.06.18/parameters/fraglib_torenv.dat
| |
− | | |
− | This should generate a new list of torsion environments titled unique_full_sorted_fraglib.dat
| |
− | =='''II. Performing a GA using 2NNQ'''==
| |
− | | |
− | For this part a new directory will be created in the 2NNQ_GA. This will just be 2NNQ_GA_results. cd into that directory and create a new file titled 2NNQ_GA.in.
| |
− | mkdir 2NNQ_GA_results
| |
− | cd 2NNQ_GA_results
| |
− | touch 2NNQ_GA.in
| |
− | Following this dock6 will be performed on the molecule
| |
− | dock6 -i 2NNQ_GA.in -o 2NNQ_GA.out
| |
− | Input the following in order to get the GA working properly
