[gmx-users] dssp error

[Albert]

hello:
  I am trying to run do_dssp by command:

do_dssp -s md.tpr -f md.trr -b 400 -e 500 -o fws_ss.xpm

but it said:

Select a group: 1
Selected 1: 'Protein'
There are 35 residues in your selected group
trn version: GMX_trn_file (single precision)
Reading frame     400 time  400.000
Back Off! I just backed up ddbXn2WY to ./#ddbXn2WY.1#
