<P>
Hi!<BR>
I am attempting to simulate a protein with a modified amino acid using the Gromacs force field with hydrogens for NMR. I have built the RTP and TOP files using PRODRG. <BR>
I need to know what is the rtp file? relevant to the above force field such that I can append my rtp file. Is it the ffgmx2.rtp or ffgmx.rtp?<BR>
Thanks<BR>
