[gmx-users] Inconsistent shifts in periodic molecules

2012-04-18 Thread Andrew DeYoung
Hi, I am a little embarrassed to ask this, especially because there are many posts related to the term "inconsistent shift." Unfortunately, I still cannot seem to find the answer to my question. What is an inconsistent shift? Is it related to constraints or restraints? Or is it more related to

Hi Mark thanks for your reply, I'm not sure the problem is that these restraints are inappropriate, but the problem might be the sheer number. For example if i restrain a fairly large number of atom distances (say 100 Calpha distances) to the same length they are in the structure after minimis
