list index out of range

Asked by Douja Darej on 2019-10-18

Heyy !!

I am very new to Madgraph (using the new version v2_6_7, and trying to test this RPV model. But I have a problem that I guess is not attached to this. Probably there is something missing ( like an install ... ). Here is what I get when I launch my process using >launch myprocess :
Command "launch myprocess" interrupted with error:
IndexError : [Fail 5 times]
  list index out of range
Please report this bug on
More information is found in 'MG5_debug'.
Please attach this file to your report.

in the MG5_debug :

    raise error.__class__, '[Fail %i times] \n %s ' % (i+1, error)
IndexError: [Fail 5 times]
 list index out of range

I can't really understand where to start to know where the problem comes from, so I thought maybe it was obvious to some of you.

Thanks in advance.

This looks like that database of results is corrupted.
in principle you can just remove the following file:
and then the code will recreate the database as needed.
