hi,
I am new to Amber software and want to simulate a* helical peptide *in
water using ff12Sb force field. I need to cap this peptide with ACE and NME
groups.
I have generated the helical peptide using Chimera and capped it using DS
visualizer. However, the parameter and topology files are not generated and
am I get the following error:
FATAL: Atom.R<NME 19>.A<C 7> does not have a type
Failed to generate parameter.
Can someone suggest how to get rid of this error.
Thanks,
Harshala Haldankar
