Using DSSP with costum PDB file

[JoanaMPereira]

Hi! Thanks for reimplementing DSSP and adapting it to the current standards in structural biology.

I was wondering if there is any way one can also use it with custom PDB files with just coordinates. That was possible with the previous versions of DSSP, but it seems this is not possible anymore. I know it is an outdated need, but it would be nice to have a legacy mode of the input formats as well.

Thanks!

DSSP still supports PDB-format input, but it has to be PDB format so just a bunch of ATOM records is not officially supported. Having a HEADER record and a CRYST1 record are the bare minimum to make something a PDB file, but you can get away with less. This makes me wonder which DSSP version you are using. I'm using 4.5.7.
