Dear users,

I want to analysis the change of a helix in secondary structure during
simulation time but I get the following error. Why am I getting this error?

do_dssp -f traj.xtc -s topol.tpr -o ss-helix4.xpm -sc ss-helix4.xvg -n
helix4.ndx
Select a group: 19 (helix4 includes 7 atom)

Fatal error:
Failed to execute command: /usr/local/bin/dssp -na ddUYNXx9 dd1AmuF4 >
/dev/null 2> /dev/null

Thanks in advance
