Dear Wendy,
the problem you reported is due to the compilation of amber, that was
customed in a way that is not able to deal with the 10-12 coefficients
you introduced in you parm file. You should recompile at least sander
inserting in your MACHINE file, located in the directory amber7/src,
the line
setenv MACHINEFLAGS "-DHAS_10_12"
and then recompile the program. This line only allow to recompile amber
in a way so it can recognise this coefficients for short range
interactions if present in the file you submit.
