OSError : [Errno 13] Permission denied

Update: While reading through the outout text, I found this message after setting the lhapdf path:

set lhapdf /nv/blue/james/private/MG5_aMC_v2_3_0/LHAPDF-6.1.5/lhapdf-config
/nv/blue/james/private/MG5_aMC_v2_3_0/LHAPDF-6.1.5/lhapdf-config does not seem to correspond to a valid lhapdf-config executable.

While I know it is there, ie cat /nv/blue/james/private/MG5_aMC_v2_3_0/LHAPDF-6.1.5/lhapdf-config gives:

#! /usr/bin/env bash

Is there something else I need to do to make this a valid location for MG5?

Hi James,
can you check if you have execution rights for lhapdf-config?
It looks like it cannot be executed...
Cheers,

Marco

Hi Marco,

That fixed it! I'm sorry I missed that, I guess I just assumed it would have built in a way that gave it execution rights. Thanks for your help!

Thanks,
James
