contur_path is not correctly setup

[Pablo De la Torre]

When I run rivet without contur, everything seems to work fine. But when I set run_contur=true, I get this error message:

INFO: running rivet
Command "generate_events run_01" interrupted with error:
Exception : contur_path is not correctly setup. Should be the directory of contur and conturenv.sh script

[Sihyun Jeon (shjeon)]

Well as the log suggests, did you install contur?

[Pablo De la Torre (pablodelatorre)]

Yes, I installed contur using "install contur". As the error said, I have found the folder where contur and conturenv.sh are, it is /home/usuario/Software/MG5_aMC_v3.5.3/MG5_aMC_v3_5_3/HEPTools/contur/contur. But I don't know which environment variable I have to assign to this path. Do I have to do "source contuenv.sh" or it is only needed when I am not installing contur from within Madgraph? Thanks

[Sihyun Jeon (shjeon)]

ah this is possibly because contur setup has changed a bit and we only tested the compilation..

can you change the line in [1]

[1] https://github.com/mg5amcnlo/mg5amcnlo/blob/3.x/madgraph/interface/madevent_interface.py#L2474

setupContur.sh to conturenv.sh and see how things change?

@ Olivier
I can do a proper check probably late next week
