======================================================== | SoLID GEMC Tracking Library | Based on the Hall A Analyzer ======================================================== This software is designed to interface EVIO output from GEMC to the Hall A analyzer. It requires: EVIO https://clas12svn.jlab.org/repos/clas12/evio/tags/evio-4.0/ Hall A Analyzer http://hallaweb.jlab.org/podd/index.html ** Environment variables EVIO and ANALYZER must be set to point to these packages ** This is designed to act as an extension of the analyzer with modifications mainly due to the fact the input files are different. It will cast the data from EVIO into a THaEvData object based on the EVIO identifier numbers. The flow goes EVIO -> SBS digitization -> THaEvData (basically plane/ wire/time + plane/wire/amplitude tuples) -> Decode -> Clustering -> Tracking Analysis Clustering I'm guessing will be constant so a separate "clustering" algorithm will be employed ======================================================== For users: To build this, you should just be able to run make and libsolgem.so shoudl be built src/ All the source files for this library example/ Example of how to load and run this library ======================================================== For developers: There are two basic ideas building on the analyzer. 1) The input files are different and are pure EVIO. We can ignore everything like EPICS, etc in the data stream. To keep from rewriting a lot of the raw data code, we'll cast the EVIO output into THaEvData. I'll need to specify this exactly, but the 'crate' will probably be fixed, the slot will be based on the manual identifier number, and the channel will be just the wire number. 2) We use the analysis flow of the analyzer and it's nice output facilities for the rest. This presumably will make everything easier in the end for mashing code from several projects together. ======================================================== Modified August 5, 2011 Seamus Riordan riordan@jlab.org
