<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I am using Gromacs 4.0.5 for umbrella sampling. I know that I can use g_wham to calculate the free energy along the constrained distance. Is there a command in Gromacs 4.0.5 that can calculates the average of any other obserble (for example, potential energy) along the constrained distance? Thanks a lot.</DIV>
<DIV> </DIV>
<DIV>Sincerely,</DIV>
<DIV>Qian</DIV>
