May i know what is the function of having .gro file types as output?
For example, if i run pdb2gmx i can specify either .pdb or .gro. What is the advantage of choosing .gro if my software can view .pdb files directly as a visual model but not .gro file types?
For subsequent steps such as EM, equil, production, can .pdb be used throughout instead of .gro?
