Hi all, 
I'm trying to run gPPI and getting an unspecific error: 
"ERROR 1: PPPI inputs were specified correctly, but failed error checking for dependencies. This is likely a bug in the program.
One or more inputs are not correct."

Unfortunately, similar older forum posts weren't helpful here (problem with directory, etc.).

Here is the P. file as specified :
