[BioPython] dssp

[Hua Wong]

Another newbie question...

I try to use the dssp module of Bio.PDB

I looked at the
http://biopython.org/docs/api/public/Bio.PDB.DSSP.DSSP-class.html
page for the example

and get the following error.
>>> model=structure[0]
>>> dssp=DSSP(model,'0b.pdb')
sh: line 1: dssp: command not found

I think it is because my dssp isn't installed in a default-just-for-root-almighty location.

Am I right? If yes, what can I do to tell bio.PDB dssp the location of dssp...
Else, what are the other possible problems?

Thanks
