I am trying to follow the NAMD-RBCG Tutorial on Windows 10, and I am trying
to run the tcl script (fix_martini_psf.tcl) to fix the files from the CG
Builder to assign secondary structures. However I ran into an issue
because I think one of the lines in the tcl file used the join function to
join the dssp path with the dsspcmbi file, resulting in a path with
backslashes. Returning an error saying it could not find the file. Once I
replaced this with the direct path to the dsspcmbi file with regular
slashes, I get a different error saying:

"bad option "../05-scripts/dsspcmbi": must be atime, attributes, channels,
copy, delete, dirname, executable ..."

Any help would be appreciated.

Thank you
