[gmx-users] Using an rtp file in an non standard directory

[Miguel Caro]

Hello,

I have created my own rtp file which I want to use in conjunction with
the OPLS force field. If I understand it correctly, the easiest way to
get pdb2gmx to build my topology would be to copy my rtp file into the
oplsaa.ff/ directory, and Gromacs looks for my molecule name inside
anything with an *rtp extension, including my rtp file. However, I have
no write permission to the oplsaa.ff/ directory of my Gromacs
installation. How can I get pdb2gmx to search inside my rtp file when
it's in a non-standard directory (e.g. in the current working directory)?

Thanks,

Miguel
