Hi all,

I'm using a fragment-based approach to parameterising a particularly large
molecule. I've already optimised the parameters for one fragment. Both
fragments share a common core indole moiety, so during the first fragment
parameterization some of the indole charges were optimized. When optimizing
the second fragment, should I update the PSF with the charges from the
previous fragment? Or leave them as the CGenFF-assigned (high penalty)
charges?
