MGME5> pythia run_01 : Attribute Error

Hi all,

I've been creating events for gluino pair production. I need to manually alter the event.lhe files after they are generated, then I wish to run pythia on these generated events. After generating 10k events, I leave MG5 and enter the process directory. While in the process directory, I type:

user> bin/madevent
MGME5> pythia run_01

Which then gives the output:

compile directory
Command "pythia run_01" interrupted with error:
AttributeError: 'MadEventCmdShell' object has no attribute 'run_card'
Please report... etc...
More information... etc...
Please attach... etc...

The full debug log is:

I was hoping that I could simply continue the whole generation/hadronization/detector simulation process after I change the .lhe files, but no such luck.

This error occurs regardless of whether or not I alter the event.lhe files. If there is a workaround I would be happy to hear it, but as it stands I see no way of continuing the process using MadGraph. (v1.5.9)
