Please find the gdml file relative to MU2E_SEARCH_PATH

[kutschke]

If I am using REve by

setup mu2e muse setup REve v4_00_00 mu2e -c /cvmfs/mu2e.opensciencegrid.org/Musings/REve/v4_00_00/REve/examples/extracted_example.fcl -s file.art

I get an error opening the gdml file:

Info in : Reading geometry from file: REve/mu2e.gdml Info in : Geometry GDMLImport, Geometry imported from GDML created Error in : Unexpected end of xml file Error in : Cannot read file REve/mu2e.gdml Segmentation fault

The soluton is to search for the GDML file relative to MU2E_SEARCH_PATH

The best place to do that is here:

https://github.com/Mu2e/REve/blob/a2e38bdb328e58dc525b31a0b634561733406dce/src/REveEventDisplay_module.cc#L232

You could also do it just before here: https://github.com/Mu2e/REve/blob/a2e38bdb328e58dc525b31a0b634561733406dce/src/REveEventDisplay_module.cc#L454

In Muse, your search path will always include something like: /cvmfs/mu2e.opensciencegrid.org/Musings/Offline/v10_27_00/build/sl7-prof-e28-p055 so you can find a gdml file relative to that location, as Offline/gen/gdml/mu2e.gdml

Note, this gdml file is part of every official build of Offline, but it does not happen by default, when you "muse build" locally. You have to ask for it, like "muse build GDML"

this is now setup for the nominal geometry but I'm having an issue with extracted for some strange reason

[kutschke]

Is your working area on a machine that I can see - if so please point me to it.

[sophiemiddleton]

give me a few mins, it could be the dataset just needed prestaging, will let you know if that was the issue (the error messages as Dave pointed out are pretty cryptic)

I have no problem running REve on extracted data with REve checked out.

no its the path which might be wrong, which data set are you using?

[sophiemiddleton]

OK, it was a dataset issue, so will put in PR now with the fixes
