Hi,
I have facing some problem when converting .pdb file to .gro and .top .
I have a .pdb of alpha d-mannose (1-6) alpha d-mannose. I was using the pdb2gmx command and 45a3 forcefield .
Showing the fatal error:
Atom O in residue ADE 1 not found in rtp entry with 25 atoms
while sorting atoms
and
Warning: 'ADMA' not found in residue topology database, trying to use 'ADE'
Warning: 'ADMA' not found in residue topology database, trying to use 'ADE
but in ffG45a3.rtp I could not found any ADE ...........
so I was confused ...
Please give me some suggession.
The format of my M6M.pdb is,
