FSRoot is an alternative to DSelectors that uses flat trees.
There are two steps:
(1) Use FlattenForFSRoot (hd_utilities/FlattenForFSRoot/flatten) to generate flat trees from the standard analysis trees.
> flatten -i [input analysis file name] -o [output FSRoot file name]
Run flatten with no flags to see further run options. This should work for data, reconstructed MC, and thrown MC.
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.
