Re: [AMBER] RESP charge derivation

Hi,

See this: http://archive.ambermd.org/201004/0684.html

I think RESP expects a 5 column integer (i5) by default. Increasing this
limit and recompiling AmberTools has worked for me earlier. I wonder why
the default integer size is so small. It could easily be made larger or
free format by default.

Best regards,
Suman.
