If you have a directory full of .gro files that contain velocities,
and if you don't need those velocities, then you're taking up too much
space on your drive.
It's too bad, but trjconv -novel -f in.gro -o out.gro will still write
the velocities to out.gro.
Here's a small script to strip the velocities out of a directory of
.gro files. If anybody has a better idea of how to do this, then
please post ;)
#!/bin/bash
for i in $(ls *.gro); do
echo 0|trjconv -f $i -o a.xtc -novel -s $i;
echo 0|trjconv -f a.xtc -novel -s $i -o a.gro;
mv a.gro $i;
rm a.xtc;
done
