Source code file: toppush.c, line: 843

Fatal error:
Atomtype CA not found''

but is not CA the main chain alpha carbon...why is not grompp taking CA then? i can't make out where the problem lies? i little help on this shall be very encouraging.

If you're seeing this error, then you've done something wrong when combining lipid.itp with the Gromos force field file.

Thank You
