Hello:
While trying to minimize a metalloproteinunder charmm27, with ALA first
residue (nr 2), the log reports:
*Info: SUMMARY OF PARAMETERS:Info: 191 BONDSInfo: 488 ANGLESInfo: 601
DIHEDRALInfo: 47 IMPROPERInfo: 6 CROSSTERMInfo: 125 VDWInfo: 0

FOR NH3 HC NH3 (ATOMS 1 4 1)------------- Processor 0 Exiting: Called
CmiAbort ------------Reason: FATAL ERROR: UNABLE TO FIND ANGLE PARAMETERS
FOR NH3 HC NH3 (ATOMS 1 4 1)*
The relevant part of the psf file shows that the first residue was patched

Apparently the system does not complain about the metal center. I never met
that error with patched NTER. Thanks for advice
