Now I have to perform WHAM analysis using gmx wham. As my system (Protein-ligand system) has the reaction coordinate as the center of masses between the protein and ligand I have to supply the .pdo file as suggested in gmx wham help menu. I would appreciate if anyone could help me to generate these pdo files because I have not encountered any option to generate them.
.pdo files were umbrella sampling output files from ancient versions of GROMACS.
Support for their interpretation is maintained only for backwards compatibility.
Look through the tutorial again; nowhere does it use .pdo files and yet it still
calculates a PMF :)
