Dear DSSP user!

To run DSSP, type:

dsspcmbi PDBSourcefile DSSPDestinationfile

(Also Windows users have to open a terminal and 'cd' to the DSSP directory!)

The above will not work in MacOSX and may also fail in Linux, in this case you have to compile DSSP yourself, type:

./DsspCompileGCC 

The CMBI version of DSSP contains some additional code to make sure you get a correct output even if the PDB file is a bit messy. See the DsspCMBI.c source code for details. It has been tested with all the official PDB files available.

In the (very unlikely ;-) case that you find any bugs (sorry, unexpected features) in the program, please report them to Elmar.Krieger@cmbi.ru.nl , as long as they affect the output given for true PDB files obtained from the RCSB. A bug-fixed source file will then be mailed back to you.

Notes about other programs: They often expect the DSSP executable to be named 'dssp', so you have to rename 'dsspcmbi' to 'dssp' (Linux/MacOSX) or 'dsspcmbi.exe' to 'dssp.exe' (Windows).
