[Rivet] HEPMC interface being weird in 2.6.0

[Christian Gutschow]

Hi Andy,

I was using:

rivet —ignore-beams -a MyAnalysis —pwd jets.hepmc2g

Nothing too controversial I would have thought...

Cheers,
Chris

I'm using custom routines and 2.6.0 without problems. What exact command are you running? Don't think we changed any command-line flag parsing, but I can't think of anything else...

Hi,

I have a case where using 2.6.0 I can run a standard routine, say MC_JETS, on a local HEPMC file just fine, but when I want to run a custom routine on the same file, it gives up immediately saying:

Could not read from 'jets.hepmc2g'

Same behaviour even if I zip the file. When I switch back to 2.5.4, it works again using both routines.

Any ideas what’s changed / how to fix this?

(I’m using HEPMC 2.06.09)

Cheers,
Chris
