Hello:
I am using Gromacs4.6 and I extract one of my frame into .gro file by
command:
trjconv_mpi -f md.xtc -s md.tpr -dump 25000 -o md.gro
I found that the velocity information was not present in this
25ns-md.gro file:
Generated by trjconv : Protein t= 25000.00000

1TYR CD1 11 1.745 3.930 8.520
1TYR HD1 12 1.847 3.967 8.520
...
Does anybody knows what happen? The final md output md.gro file do
contains velocity information:
