Dear prof.
i use the the gromacs 4.6.1 on my centos6.4 system. After MD ending, i
use the do_dssp -f md.xtc -s md.tpr -o secondary-structure.xpm -sc
secondary-structure.xvg to analyze the secondary structrue of the protein.
when i perform the do_dssp and select MainChain , the fatal erros come out
as follow;
Fatal error:
DSSP executable (usr/local/bin/dssp) does not exist (use setenv DSSP)
it is means thant i don't install do_dssp? however, when i perform the " which
do_dssp" at the terminal, the termianl output
"/usr/local/gromacs-4.6.1/bin/do_dssp. i don't know where is wrong. should i reset the
environment of the do_dssp?
do_dssp and dssp are different executables. Please read the following:
