Subject: AMBER: mm_pbsa problem: bad atom type: IP

Date: Thu May 08 2008 - 06:59:12 CDT

Dear amber user,
I'm trying to apply MM_PBSA to calculate the binding energy of my system composed by two protein.
I'm following the advanced tutorial n3 but when I run for binding energy calculation I get this error:
bad atom type: IP
Looking at the amberarchive, it seems that this problem is related to the Na+ ions added to equilibrate the charge in .prmtop file.
How can I solve this problem without modifying mdread.f file with LCPO parameters? Or, anyway, Where I have to modify this file?
