[gmx-users] Re: pullx file content with pull_geometry = position

[Bastien Loubet]

I update the post to say that we tried to make a rerun of the trajectory on
our local machine and the output of the pullx.xvg file (created with the
option -px of mdrun) is:

**********************************************

The output of the pullx.xvg file is indeed the distance between the two pull
groups, but this is very different numbers than the one obtained  during the
simulation on a cluster (see above post).
So the question stand what are the numbers given in the pullx.xvg file
created during the original simulation ?
