lhe to root conversion in MG5

Asked by A.Hayreter

Dear Pavel,

I am having trouble with lhe to root conversion in MG5_v2_1_2.
I installed ExRootAnalysis package and then I used ExRootLHEFConverter
to convert a recently generated lhe file into root one. However I get a runtime error
which states that the converter tries to read an lhe file which is not version 1.0.

The current lhe version in MG5 is 3.0, so is there a compatibility issue?

thanks.

Hi,

ExRootAnalysis was updated very recently to support lhef version 3 file.
So you just have to re-install it.

Cheers,

Olivier
