Summary of the Program

The package comprises several scripts, each with a specific purpose, aimed at facilitating the generation of molecular conformers and subsequent energy calculations. Here's a brief overview:

1. Main Script Execution:

   • The bash script main.bash invokes main.py, which retrieves the PDB structure for the protein and extracts the ligand.
   • main.py utilizes the confgen function from confgen_rdkit.py to generate conformers using rdkit.

2. Conformer Generation:

   • Conformers are segregated into different xyz inputs and stored in distinct directories, such as molecular_files/rdkit_conformer/.

3. Energy Calculations:

   • Energy calculations, for both solvated and non-solvated conformers, are submitted batchwise using call_slurm.tcsh.
   • Python scripts getEnergy.py and getEnergy_sol.py are employed to extract energies and sort conformations based on their energy.

4. Bound Ligand Conformation:

   • Energy calculations for the bound conformation of the ligand are also submitted.

5. CREST Calculations:

   • CREST calculations are independently submitted inside the molecular_files directory.

This package streamlines the process of molecular conformer generation and energy calculations, providing a comprehensive toolkit for drug discovery endeavors.
