A collection of tools for analysis of the HPS data sets, which do not already have a repository location elsewhere.
- Sub directory that contains the code to create simple "flat" NTuple type ROOT files from LCIO or 2015/2016 DST files.
The MiniDst code creates a simple tuple style Data Summary Tape (DST) for HPS data from LCIO files. LCIO files are the files produced by the Java based event reconstruction code.
The advantages of a tuple style DST are that the data can be easily expanded, or reduced, in event size without breaking any existing code. It also makes the data easier to explore, with TTree::Draw() and the TBrowser. This type of data storage is also much easier to work with if you want to use the very powerful RDataFrame analysis framework from ROOT.
