[gmx-users] Error in -rerun

[Apramita Chand]

Dear All,
As I have specified in my earlier mail, I wanted to know which input
trajectory has to be supplied to -rerun flag in mdrun for recalculation of
electrostatic energies between protein-solvent from gromacs (as proposed by
Lindgren et al, in the paper "On the stability of chymotrypsin inhibitor 2
in a 10 M urea solution. The role of interaction energies for urea-induced
protein denaturation",)
<http://pubs.rsc.org/en/content/articlehtml/2010/cp/b925726h>.

As I was confused about the input files, I am doing a trial where I am
supplying the production run trajectory to -rerun.
This involves making changes in the cut-offs and applying cut-off scheme
rather than PME.

My cubic box length is 3.20 and I cannot specify any cutoffs exceeding half
of this length,(without changing the box length). So I apply whatever
cut-offs are possible with my present box size.

I am getting the error:

*Rerun trajectory frame step 0 time 0.000000 has too small box dimensions*

after running mdrun


Please help me troubleshoot the issue

Thanking you,
Yours sincerely,
Apramita Chand
