[gmx-users] unable to run energy minimization on short peptide

[Jaimin Shah]

Dear Users:

Please suggest the solution to the following error that occurs when I run 
grompp -v -f em -c b4em -o em -p speptide
in one of the steps in the simulation of Ribonuclease S-peptide (the
examples section of the tutorial):

ERROR: One of the box vectors is shorter than twice the cut-off length.
Increase the box size or decrease rlist.
Fatal error: There was 1 error
