Re: [AMBER] changing intrinsic GB radii

we have done it by changing the leap source code, or writing scripts
to modify the prmtop. i don't know of any way to use a leap command to
do it.

I've seen recent papers in which they got excellent results  (Lin and Shell 2009; Kim, Jang, Pak ; Kim Jang Pak 2007). In these cases they reduced some intrinsic GB radii (cf Geney et al 2006). Is there a simple way to change these radii in AMBER10? The only possibilities I've come up with are manually editing the prmtop or delving into the source code. Can this be done with an frcmod file or via leap?
