[QE-users] Pseudopotentials error: not a valid URI

[Lorenzo Paulatto]

Dear Vendant,
the way fortran interprets Windows file names (in particular the "\" characters and "X:" prefix) may depend on the compiler and system libraries. If you have compiled QE using WSL, you definitely have to use Unix path names relatives to the WSL installation (no idea about the details, but I'm sure Microsoft and Google can help you), if you are using some kind of native binary, then it depends on the compiler. Maybe using "\\" or "/" in place of "\" would help.

A quick solution would be to put the pseudopotentials in the directory in which you are running the code an just set pseudo_dir to "."
kind regards
