Hi!!
I am using the include file mechanism to define the topology of my
protein-membrane system.
I have a problem regarding the pope.itp file. I use a modified version
of the pope.itp from
http://moose.bio.ucalgary.ca/index.php?page=Structures_and_Topologies
(see below).That is accordingly with the pdb file that I am using ( see
bellow). However when using grompp I got this warning:
Warning: atom name 7542 in papc_topol2.top and system-clean-120xy.pdb
does not match (H1 - N)
Warning: atom name 7543 in papc_topol2.top and system-clean-120xy.pdb
does not match (O1 - H1)
Warning: atom name 7544 in papc_topol2.top and system-clean-120xy.pdb
does not match (CA - H2)
as if none of the atoms that belong to pope in the pdb match the
respective itp file.
Maybe I am wrong but seems to me that the the atoms are actually matching..
any suggestions are welcome...
Well, if you've modified the pope.itp file, then that could be a source of
error, but without substantially more information about what you've done,
there's nothing to comment on there.
The other potential problem is that the content of the [molecules] directive
must be the same as the order of the species in the coordinate file. You may be
seeing mismatches because things are out of place in the topology.
