[gmx-users] trjorder

[shahab shariati]

Hi all

I used trjorder -f ns.xtc -s ns.tpr -n ns.ndx -o ns.pdb -nshell ns.xvg -r
0.74

I encountered with Fatal error:

An atom number in group  is larger than the number of atoms in the
trajectory


What means of this error? How to fix it?

Any help will highly appreciated.
