FSRoot
From GlueXWiki
FSRoot is an alternative to DSelectors and uses flat trees.
There are two steps:
(1) Use FlattenForFSRoot (hd_utilities/FlattenForFSRoot/flatten) to generate flat trees from the standard analysis trees. Run flatten with no flags to see run options. See the FlattenForFSRoot/Documentation directory for more information.
(2) Use FSRoot (available at https://github.com/remitche66/FSRoot) to make histograms from the flat trees. See the FSRoot/Documentation directory for documentation.
