I have an no3.lib file that was provided by one of my collaborators:
https://webfiles.uci.edu/jenniet/no3/no3.lib
However there must be a problem with it, since the O-O bonds are not
defined in the rdparm file. Is there a quick way to check where the
error is in this .lib file? Or, is there an easy way to regenerate this
file?
I'm a bit new working with Amber force fields, so your help is appreciated!
With thanks,
Jennie Thomas
