So To test my do_dssp i also used this pdb. In this case when i choose MainChain 5 or other choices I obtain the same message described below and no output. I think, I have set correctly the DSSP environment variable because i have not the Fatal error:

so if you run

setenv DSSP `which dssp`
echo 1 | do_dssp -f 1HRC -s 1HRC

you get no output? do you have write permission in the work directory?
