[gmx-users] distance options for g_cluster

2008-02-16 Thread OZGE ENGIN
Hi all, I am trying to understand what type of distance can be used with g_cluster? In the manual, it is written that RMS deviation after fitting or RMS deviation of atom-pair distances can be used to define the distance between structures in the first paragraph. However, in the "other options

Justin, Following up on this, I looked back through my old e-mails and found that, indeed, you do appear to be running into a known bug. It's one I helped a guy named Bharat find, so the relevant bugzilla is from him rather than from me: http://bugzilla.gromacs.org/show_bug.cgi?id=175. It appears

The reason I commented about the use of your .tpr file is that, from your message, it seemed that you did not understand exactly how to use trjconv, and were perhaps using a different .tpr file (named topol.tpr) to simply satisfy trjconv. Your previous message said your grompp output produced a m
