Hall A Software Tools

This page: hallaweb.jlab.org/software/tools Updated June, 2017 R. Michaels

The purpose of this page is to provide software tools contributed by Hall A users, especially the smaller lesser known tools, so others may avoid "re-inventing the wheel". If you have something to contribute, please contact Bob Michaels (e-mail: rom@jlab.org). Contributing authors of smaller software are not expected to support future data; these codes are useful starting examples that may require modification.

Small Lesser-Known Tools
- Hall A Wiki on Software.
- A simple standalone analyzer which unpacks ROCs and BANKs and fills a ROOT histogram. (Oct 2016)
- J. Singh's tool box of scripts to extract EPICS and HALOG data.
- Rikki Roche's Event Display Tool to look at VDC tracks traced to scintillators and FPP. Untar and see README.
- Bryan Moffit's online GUI for online presentation of ROOT results.
- A set of simple scripts to use batch farm for the Podd ROOT/C++ analyzer. Untar, see README. Version from Jan 2004.
- W. Boeglin code to convert espace database into sql form and here is the README file that is also included in the tar file.
- Bob M's C++ utilities CODA classes, Scaler package, a standalone event decoder.
- Bob M's simple C++ examples to read a CODA file (or ET online data) and fill ntuples and histograms in ROOT. Untar these and see the README:
  - A simple standalone analyzer which unpacks ROCs and BANKs and fills a ROOT histogram. (dated Oct 2016)
  - FLASH ADC analyzer (dated Dec 2006)
  - Parity ADC analyzer (dated Jan 2007)
  - DVCS test stand analyzer (warning, dated Aug 2003).
- Bob M's simple Fortran/Paw examples to read a CODA file, fill histograms with Fastbus data: An event check code and a helicity check code.
- Paul Ulmer's tools for halog, scalers, and VDC hits (see readme files there). E.g. you can extract variables from halog, or extract scalers from a CODA file to put into Paw ntuple.
- Hassan Ibrahim's tools to extract stable current periods of time, used in E01020.
- For some of the above examples you may need the EVIO library (make 'libcoda.a'). Careful! this is a very old version of EVIO. (EVIO comes from the DAQ group, see below).

EVIO

EVIO is supported by the DAQ group.

To find the modern version of EVIO, do the following.
Go to http://coda.jlab.org.

Click on "Core Packages",  then "Event IO (evio)", then, on right, look at "User's guide".
Can also look at "EVIO C++ API" on left side of page for details of API.
This is also a C and a Java lib.

To compile with EVIO you typically need to set these two environment variables:  
EVIO_INCDIR and EVIO_LIBDIR must point to ./include and ./lib of the EVIO distribution

I notice a recent version is
 
           /site/coda/3.02/src/evio-4.4

There are subdirectories Linux-x86_64 and Linux-i686
The former is for 64-bit machines; most machines are 64-bit nowadays.
In each of these subdirectires is a ./bin, ./include and a ./lib
