The MID tracking takes as input the clusters and returns a vector of reconstructed tracks. The magnetic field in the trigger chambers, placed behind an iron wall, is negligible, so a straight track is used.

The algorithm has some configurable parameters in TrackerParam.h. Option --configKeyValues "key1=value1;key2=value2;..." allows to change them from the command line.

See instructions here.

In another terminal:

runMIDTracking --id 'MIDtracker' --mq-config "$O2_ROOT/etc/config/runMIDtracking.json"
