The default particle selection criteria can be found here: [1]. All the selections can be changed in the command line or in the Jana configuration files as followed (p29):

- Changing the particle time cut:

COMBO_TIMECUT:X_Y Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and time cut in ns, respectively

- Changing the track PID, the timing (treated above), E/P and dE/dx are used

- EOVERP:X_Y=Z1_Z2 with X, Y, Z1 and Z2, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and E/P cut in ns, respectively
- DEDXCUT:Low_X_Y=Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and [FIXME] cuts in [FIXME], respectively
- DEDXCUT:High_X_Y=Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and a function of p in GeV/c, respectively

- Changing the meson/baryon, missing mass squared, or missing energy:

- Meson/baryon mass:
- IMCUT:Low_X=Z
- IMCUT:High_X=Z

- Missing mass squared:
- MM2CUT:Low_Func_X=Z
- MM2CUT:High_X=Z

- Missing energy:
- MISSECUT:Low_Func="function"
- MISSECUT:High="value"
