add process

Asked by Zhaowei Song

I was studying a process with a background of g g > z z and q q > z z.My syntax is :
generate g g > z z [noborn=QCD]
add process p p > z z
launch
Then I encountered a bug
Command "launch" interrupted with error:
AttributeError : 'HelasMatrixElement' object has no attribute 'compute_all_analytic_information'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.
I wonder how I can generate this process.

You need to generate them seperatly, we do not have the infrastructure to compute tree level and loop-induced simultaneously.
