Tool to access the Analysis production Data
Project description
Analysis Production Data
EXPERIMENTAL prototype of Python module to fulfill DPA’s grand task https://gitlab.cern.ch/lhcb-dpa/project/-/issues/134.
Usage
The apd package is available in the lb-conda default environment.
From Python
The Python module allows interacting from analysis scripts, doing e.g.
In [8]: import apd In [9]: datasets = apd.get_analysis_data("SL", "RDs") In [10]: datasets(datatype="2012", polarity="magdown") Out[10]: ['root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000002_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000005_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000003_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000001_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000004_1.bsntuple_mc.root'] In [11]:

The apd-cache command allows caching the Analysis metadata to a specific location.
