An example analysis code with alphatwirl and data frames
- tbl_roc.py in xi-roc-cafe analyzes a small number of data frames, highlighting data frame operations - data frame file names are hard-coded
- concur-anon-comp is an example of how to analyze a large number of data frames. here, the scripts don’t know the input file names. instead they find relevant input files by the file name conventions, analyze a large number of data frames in parallel.
- In order to highlight the above point, concur-anon-comp includes only a few data frame operations, combining components into processes and summing over categorical variables

Move to a work dir:
cd /some/work/dir/
The code runs in any envriomment with Python 2.7, ROOT 6, and several other common libraries.
In this example, we will run in cmsenv
.
Source cmsset_default.sh
if it is not done yet.
source /cvmfs/cms.cern.ch/cmsset_default.sh
Check out cmsenv
if it is not done yet.
export SCRAM_ARCH=slc6_amd64_gcc530
cmsrel CMSSW_9_4_3
Enter the cmsenv
:
cd CMSSW_9_4_3/src/
cmsenv
cd ../../
Check out this repo:
git clone --recursive https://github.com/TaiSakuma/concur-anon-comp.git
Print the commants to be executed
./concur-anon-comp/yield/print_commands_heppy.py
If you want to execute them all, you can just pipe to sh.
The option --print-jobs
shows the list of the jobs.
./concur-anon-comp/yield/print_commands_heppy.py --print-jobs
It will print:
summarize_trees_SM
combine_tables_into_process_SM
aggregate_categories_SM
(Optinally) summarize trees and create data frames with alphatwirl
./concur-anon-comp/yield/print_commands_heppy.py summarize_trees_SM | sh -x # (optional)
The output of the above optional cmmand is stored in this repo. So if you skip the above command, you can copy the result
cp -r concur-anon-comp/example_tbl/tbl_20180122_01 . # (alternative to the above command)
You should look at the files in the dir tbl_20180122_01/SM/
.
Combine components into processes:
./concur-anon-comp/yield/print_commands_heppy.py combine_tables_into_process_SM | sh -x
You should look at the files in the dir ls tbl_20180122_01/SM/
again and understand what happened.
Aggregate categoreis:
./concur-anon-comp/yield/print_commands_heppy.py aggregate_categories_SM | sh -x
Again look at tbl_20180122_01/SM/
and understand what happened.
