Hi Paris,
I'm running Hans-Christoph's pd-0.38.4-extended-RC2 on OSX. There are vasp files in /doc/vasp and in /doc/5.reference I've tried setting every path that I can think of so that vasp loads
but am having no luck.
Have you included vasp into the list of external libraries to load? That is, you have to add vasp to the files in the startup dialog. Additionally there are some abstractions used by vasp, so that the path should also include the folder where VASP-HELP.pd etc. reside.
best greetings, Thomas
