This page provides a very brief overview of the GlueX-specific software used between recording data and publishing results. In time, it should become populated with links to more detailed documentation..
Databases and other tables are described here. (Naomi, Sean, David L.)
Raw and reconstructed data – halld_recon
- ● Raw data are saved by the DAQ system in the EVIO file format (more details here) and processed using programs in halld_recon. (Mark)
- ● hd_root is used to analyse EVIO (see above) and REST (THIS NEEDS LINK) data with plugins for monitoring, Calibrations, and event reconstruction (Sean [calibrations] - & Mark)
- ● REST files are in HDDM format which stores reconstructed physics objects (no detector hit information) (Richard)
Simulated data - halld_sim (Overview)
- ● Event generators generate simulated physics data (particle, momentum, track angle) in HDDM format. (Simon & Malte; Richard)
- ● hdgeant4 models the measurements (detector hits) produced by those tracks (Richard)
- ● mcsmear models the detector resolution to match the MC simulation results with actual measurements. (Richard)
- ● MCWrapper runs all of the above on demand. (Sean, Peter)
Reaction channel analysis
- ● ReactionFilter plugin is used to find the events corresponding to a particular reaction to make Analysis Trees. The basic ideas and steps are outlined here(Igal, Beni)
- ● Requests for analysis trees are collected via a webpage, and launched bundled together on the JLab farm. Lists for already existing trees are kept on the Private wiki under "Run Period Info" and "Analysis Launches", for example here. (Alex A)
Analysis Tree analysis
- ● DSelectors are used to analyze "Analysis Trees" (see reaction filter above) to generate histograms of invariant masses, angular distributions and more. It can also generate highly reduced output trees for further analysis reducing the I/O. See Analyze an Analysis Tree for more details. (Beni)
- Other Analyses approaches like python code on flat trees? (Jon.Z, others)
- ● FSRoot is an alternative to DSelectors that uses flat trees. (Ryan)
- ● AmpTools (GitHub, User Guide) is used for partial wave analysis. GlueX specifics are documented here (PRIVATE) (Malte)
- ● PyPWA is an alternative software package to perform an amplituded analysis based on python. Documentation details can be found here (Peter, Carlos, Maj)
