Dear People,

Dear gromacs users,
I’m following this tutorial ->
http://md.chem.rug.nl/cgmartini/index.php/proteins
in order to performed a CG simulation of an specific protein in a water box.
My problem is that when i’m trying to solvate my protein with genbox, by using
the next command:
> genbox -cp COR15
I ran the md5sum but it does not match with any of the hashes.What should I
do now?

The g_polystat tool arranges the Rg eigen vectors in the descending order.

Thank you Sir. Sorry for the late reply. So, the changes like dihedral
angle for C8-C9=C10-C11 should be 180 instead of 0 in trans state. Are
there any other adjustments I should make to build the trans lipid isomer
topology from cis? Thank you for your valuable time and concern.
