Comparisons and Checks

Compare general ROOT files

In order to comare the content of two ROOT files, you could use the Artus tool

compareRootFiles.py [-a] <file1.root> <file2.root>

Look into EDM Files

CMSSW provides the tool

edmDumpEventContent <file.root>

to list the content of EDM files (e.g. AOD or miniAOD).

Comparing Artus configurations

Artus configurations are JSON dictionaries. The can be either JSON files like the one that the Artus Wrapper constructs, the TObjString config in an Artus output file or just strings containing the content "{\"key" : \"value\"}". Every script in Artus, which takes a JSON configuration as input, accepts these three kinds of configurations.

Artus Configurations can be compared with the script

artusConfigDiff.py [-h]

To compare just two files, do

artusConfigDiff.py <output1.root> <output2.root>

Two pipelines in the same file are compared with

artusConfigDiff.py <output.root> <output.root> -1 <pipeline 1> -2 <pipeline 2>

The script outputs the differences in a way similar to diff, but it might be convenient to use the printed meld command to see the differences side-by-side.
