MCWrapper jana1 configuration option for hd_root?

[Elton Smith]

Dear Software experts

I have just recently tried to revive my NPP event generator/analysis and found that MCWrapper was not (correctly) processing the output of mcsmear. When I run gluex_MC.py directly from the software repository, the command to hd_root contains the outdated configuration for jana1 of —config=filename.cfg. If I use the jana2 configuration option of —loadconfigs filename.cfg, it produces output as expected. Either there is something in my environment (file attached) that is causing the issue or else MCWrapper needs to be updated with the correct configuration parameter. 

I have highlighted in red the relevant sections. When the wrong configuration option is used, the hd_root file is empty (487 bytes), but with the correct option the file contains the expected histograms. The hd_root terminal outputs are attached separately so they do not obscure the main point.

It would be nice is someone else could confirm this MCWrapper issue with a working environment.

Thanks, Elton

p.s. To Alex and Simon that have helped along the way, the ccdb access was a red herring that I thought made a difference, but I now see that it has to do with the options to hd_root.

Hi Elton,

This is indeed an issue with MCWrapper.

It was an oversight on my part that jana2 now needs other flags compared to jana1. We will need to implement some switches so that MCWrapper knows how to handle the passing of config files.

Thanks for pointing this out.

Cheers,

Peter
