Parse simple root files into memory as dictionaries or purpose-built objects. Convert objects into pandas DataFrames for ease of processing.
Requires ROOT with pyroot installed.
Clone this repository and install
git clone git@github.com:ucn-triumf/rootloader.git
cd rootloader
pip install .You will need to re-run the last line of the above upon every pull, unless you add the -e flag like this: pip install -e .
Note that this may not work on all systems, particularly windows systems.
from rootloader import tfile
# read file
fid = tfile('myfile.root')
# key values can be accessed as attributes or as keys
# say there's a tree named "tree1". We can access it as
tr = fid.tree1
# or
tr = fid['tree1']
# get a pandas dataframe from the tree (the tree is left unaltered)
df = tr.to_dataframe()
# try to convert all file contents to pandas dataframes, and replace keys with these dataframes
fid.to_dataframe()
