[gmx-users] selecting res CYS from G53a5 using pdb2gmx

[Payman Pirzadeh]

I had modified three files: aminoacids.rtp, aminoacids.hdb and
residuetypes.dat. All these modifications were done prior running pdb2gmx.
So, I will be glad if you could let me know what the problem is.
Best,

Payman

I'm glad you found a solution, but for the purpose of being thorough I need
to say that this should not be necessary.  A residue listed as "Protein" in
residuetypes.dat, if added prior to running pdb2gmx, should lead to seamless
integration in the topology when running all subsequent steps in preparing
the system.  It is unclear to me what's going on here.
