Hi everyone,

I would like to prepare a few proteins for MD and I would like to do it on my machine. I prepare one system and I want to prepare the others applying the same protocol as charmm-gui. My problem is that charmm-gui tar.gz file has all steps needed but I do not understand how charmm-gui converts the pdb.cif to the first crd and pdb (pdb_proa.crd and pdb_proa.pdb).

Does anyone knows how charmm-gui do these conversion?
