[gmx-users] Problem with g_rdf

2013-02-20 Thread Thomas Schlesier
My understanding is the following: If you performed a simulation and then analyse it with different values for 'nrexcl' the results will differ since a different amount of interactions are excluded. It seems that the exclusion only helps for '-rdf atom' and not for '-rdf mol_com'. But the under

Dear all, I have a question regarding g_rdf. My system consits of 10 disacchardids (in the following A-B, with A-ring/monosaccharid and B-ring/monosaccharid) and i want to determine the RDF (with flag '-rdf mol_com')for A-A, B-B and the intermolekular for A-B A-A and B-B is no problem. But fo

Hi everyone, I ran a water simulation and I tried to calculate radial distribution function OO but I get strange peaks from r =1.5nm onwards. I have 8 atoms in a box of 9.5. I post the graph as an attached file. Please does anyone have an idea of what might be going on? Thanks, Carla rdf_
