scripts

This directory contains various scripts to perform analysis tasks.
The general assumed structure are like the following:

CORE/
    .git/
    ...
    Makefile
    CMS3_CORE.so
    ...
YOUR_CORE/
    .git/
    ...
    Makefile
    libYOUR_CORE.so
    ...
SOME_PACKAGE/
    .git/
    ...
    Makefile
    libYourPackage.so
    ...
ProjectMetis/ # https://github.com/aminnj/ProjectMetis
    .git/
    ...
    Makefile
    libYourPackage.so
    ...
plottery/ # https://github.com/aminnj/plottery
    .git/
    ...
    Makefile
    libYourPackage.so
    ...
.git
ScanChain.C # your looper or whatever
...
ScanChain.h
...
bootstrap.sh
...
scripts/ # <---- this package
    .git
    setup.sh
    root.sh
    run.sh
    run.C
    ...

See this WWW analysis code as an example. In particular note the bootstrap.sh in that package.

Once you have setup like this, you setup your scripts/ like

$ source scripts/setup.sh

The scripts/ assumes ScanChain.C or whichever is your looper has EXACTLY the following format:

void ScanChain(TChain* chain, TString output_name, TString option_string, int nevents)

Then, you can run over a root file with this ScanChain by issuing a command like:

$ run.sh /path/to/ScanChain.C /path/to/output.root Events 1000 'OptionString' '/hadoop/cms/store/blah/cms3/NewPhysicsMCNtuple/merged_*.root,/hadoop/cms/store/blah/cms3/SuckySMBkg/merged_*.root'
         ^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^ ^^^^^^ ^^^^ ^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
         Use this ScanChain   Make your output      Tree   #   Any additional  Comma separated list of inputs or input pattern.
                              based on what each    in     of  options         Please note that when using wildcards '*' use quotes properly.
                              ScanChain does        input  evt ScanChain needs Also, you can only use wildcards at the base level names. (e.g. merged_*.root and not /hadoop/*/*/merged*.root)
                                                           to                                                                                                                ^ ^
                                                           run                                                                                                          These will fail. (feature request?)
