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.
