==May==
===Week of the 6th===
I acquired and installed GEMC, COATJAVA, and CED on Ubuntu 16.04. Installation instructions can be found [[DF JLab_Software_Install_Instructions|here]].
====GEMC Install Notes====
GEMC and the common environment are found [https://www.jlab.org/12gev_phys/packages/sources/ here]

There was some trouble in installing the common environment (ce) due to an [https://en.wikipedia.org/wiki/AWK awk] program (mawk, in this case) segfaulting. I was able to get around this by downloading a different awk program, gawk. After downloading the ce I had some trouble with the default version of Geant4; updating the Geant4 version numbers in ce/settings.xcconfig and ce/versions.env to 4.10.04.p01 resolved the issue.

After the GEMC install proper, it was also necessary to install the clas12Tags repository, where [https://en.wikipedia.org/wiki/SCons scons] took issue with an undefined variable in physcisList.cc. Uncommenting the line which defined theParticleIterator allowed the tags to be compiled.
====COATJAVA Install Notes====
Release versions can be found [https://github.com/JeffersonLab/clas12-offline-software/releases here]. Otherwise, one must clone either the development version or a fork of it.

Attempting to run any of the coatjava scripts with <code>./ChupaThingy</code> throws a source not found error, use <code>bash ChupaThingy</code> instead.

====CED Install Notes====
Downloads can be found [https://userweb.jlab.org/~heddle/ced/builds/ here].
===Week of the 13th===
Finished Troubleshooting installs for the most part.

Wasn't seeing any meaningful events from GEMC. Took the issue up with Dr. Forest who showed that it was likely a combination of bad starting vertex placement and small sample size. He suggested using Lund files instead. I currently have one that produces 26 usable events. In time I'm going to have to learn to create my own.

TODO:
*Ensure that my development build is using the correct mag fields.
*Get a local database setup
*write up what hits, clusters, segments, and crosses are.
