I want to simulate two peptides, which have same sequences. I try the following
methods, but they didn¡¯t work.
1. I put two peptides in a file using SYBYL software, But GROMACS
think them as a
protein. So LINCS warning turned up and 1-4 interactions also showed up and the
2. I found some suggestions from GROMACS Mailing List and I tried giving chain
identifiers. But it doesn¡¯t work. I think I didn¡¯t add chain identifier. Can
tell me how to add chain identifier? Can you tell me how to do it?
3. I build the two topologies on separate files and combine them, but
get the same
error as the first method.
Can you tell me how to treat detailedly? Thank you in advance!
