Re: [gmx-users] gmx rmsdist: rmsmax vs. rmscmax
Hi, thanks for the reply. I now have another question regarding the the rmsdist tool: I'm confused why my rmsmax value seems so small. Right now I am simulating a box of water only. I'd like to get a matrix of all the atom-atom distances for a single frame in my simulation, so use the following command: gmx rmsdist -f nvt.trr -s nvt.tpr -mean -nosumh -b 100 -e 100 However, this gives an rmsmax = 0.000345129, which is smaller than a water molecule, and Im not sure why. I'm also curious why I need to supply a topology file if all I want to calculate is the interactomic distances. I'm likely misunderstanding this tool... Thanks in advance for the help.

Hi What is the difference between the rmsmax and rmscmax values written to the screen when running gmx rmsdist? Thanks.
