[Rivet] HEPMC interface being weird in 2.6.0

[Christian Gutschow]

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
