"Error in <TExMap::Remove>" when running over large input files
08 June 2017
When running over large input files, at some point MAUS will spit out millions of lines like this:
Error in <TExMap::Remove>: key 503057872 not found at 23565 Error in <TExMap::Remove>: key 292471040 not found at 5611 Error in <TExMap::Remove>: key 407814496 not found at 38014Steps to reproduce:
- Download a production MC (e.g. http://gfe02.grid.hep.ph.ic.ac.uk:8301/Simulation/MCproduction/000000/000000/000035/) - downloading 260+ files is sufficient
- Merge them, for example with the attached script (modify paths etc. as appropriate)
- Run MAUS over the merged file (it is not necessary to include any modules other than the inputter. Error output should start around Spill 506.
