Check if your Protein is named Protein in your topology of the
[ moleculetype ]
; name nrexcl
- and the system.
[ molecules ]
; Compound #mols
Sometimes a chainidentifier may creep into the name. (e.g. Protein_X)
You would then have to adjust the name within the topologie and/or
mdp-file. I don't know if Gromacs is case-sensitive.
I hope this is of any help .
