[gmx-users] angle analysis

[Zuzana Benkova]

Dear GMX users,
I want to analyse th ebond angle. I have used

mk_angndx -s md1.tpr -n angle.ndx

to prepare an index for g_angle.

After
  g_angle -f md1.xtc -s md1.tpr -n angle.ndx

I have obtained

Software inconsistency error:
Not supported in get_stx_coordnum
  Most likely this is a trivial question and I did some stupid mistake  
but I would be thankful for help. Thank you in advance
