ATLAS "good run list" utilities

Project description

About

goodruns provides an implementation of an ATLAS “good run list” (GRL) reader/writer in Python, and collection of useful command-line tools.

Requirements

goodruns requires at least Python 2.5 and only depends on modules in the standard library. Unlike the standard ATLAS GoodRunsLists package, goodruns does not depend on ROOT for XML processing unless you are reading from or writing to a ROOT file (see below). For better XML reading/writing goodruns will optionally use lxml if installed. Install PyYAML if you would like to convert GRLs into YAML format.

Installation

The easiest way to install goodruns is with pip. To install for all users:

sudo pip install goodruns

To install in your user site-packages directory (also see below):

pip install --user goodruns

If you have obtained a copy of goodruns yourself use the setup.py script to install. To install for all users:

sudo python setup.py install

or to install in your user base directory:

python setup.py install --user

If installing in your user site-packages directory be sure to add ~/.local/bin to your $PATH:

export PATH=${HOME}/.local/bin${PATH:+:$PATH}

You may specify a different location for your user site-packages directory by:

export PYTHONUSERBASE=/path/to/alternate/.local

To install the optional dependencies:

pip install -U -r optional-requirements.txt

Usage

An example of how to use goodruns:

from goodruns import GRL

grl = GRL('grl.xml')
# or:
grl = GRL('http://atlasdqm.web.cern.ch/atlasdqm/grlgen/path/to/grl.xml')
# or (if '/path/to/grl' is a ROOT.TObjString in data.root):
grl = GRL('data.root:/path/to/grl')

# check if the GRL contains the lumiblock 231 in run 186356:
if (186356, 231) in grl:
    # do something
    pass

The GRL is automatically optimized (lumiblocks are merged and sorted):

>>> from goodruns import GRL
>>> a = GRL()
>>> a.insert(1, (1,4))
>>> a.insert(1, (7,10))
>>> a
---------------
RUN: 1
LUMIBLOCKS:
  1 - 4
  7 - 10
>>> a.insert(1, (6,7))
>>> a
---------------
RUN: 1
LUMIBLOCKS:
  1 - 4
  6 - 10
>>> a.insert(1, (5,5))
>>> a
---------------
RUN: 1
LUMIBLOCKS:
  1 - 10

Command-line Tools

goodruns also provides a collection of command-line tools for combining, manipulating, and inspecting GRLs. As above GRLs may be XML files, URLs, or in ROOT files.

grl diff

Use grl diff to determine the GRL containing the runs/lumiblocks in A.xml but not in B.xml:

grl diff A.xml B.xml

In other words, B.xml is subtracted from A.xml. All command-line tools print on stdout. Redirect stdout to a file to save the result:

grl diff A.xml B.xml > C.xml

You may supply more than two GRLs to grl diff:

grl diff A.xml B.xml C.xml D.xml > E.xml

which results in the GRL E=((A-B)-C)-D). This is equivalent to:

grl diff A.xml B.xml | grl diff C.xml | grl diff D.xml > E.xml

The output of one command can be piped into any of the other commands in goodruns.

grl and, grl or, grl xor

These scripts implement logical combinations of GRLs. Logical AND:

grl and A.xml B.xml > C.xml

OR:

grl or A.xml B.xml > C.xml

and XOR (exclusive OR):

grl xor A.xml B.xml > C.xml

Again, these commands can be combined arbitrarily:

grl and A.xml B.xml | grl or C.xml | grl xor D.xml > E.xml

and any GRL argument can also be a ROOT file or URL:

grl and data.root:/path/to/grl http://atlasdqm.web.cern.ch/path/to/grl.xml

grl clip

Use grl clip to truncate a GRL between a starting run/lumiblock and ending run/lumiblock:

> grl clip --help
usage: grl clip [-h] [-o OUTPUT] [-f FORMAT] [--startrun STARTRUN]
                [--startlb STARTLB] [--endrun ENDRUN] [--endlb ENDLB]
                [grl]

positional arguments:
  grl

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output filename (optional)
  -f FORMAT, --format FORMAT
                        Output format: xml, yml, txt, py, cut
  --startrun STARTRUN   Start run
  --startlb STARTLB     Start lumiblock
  --endrun ENDRUN       End run
  --endlb ENDLB         End lumiblock

grl convert

grl convert can convert a GRL from XML format into YAML:

> grl convert -f yml A.xml
186178:
- !!python/tuple [125, 156]
- !!python/tuple [158, 161]
186179:
- !!python/tuple [382, 388]
- !!python/tuple [390, 390]
- !!python/tuple [396, 396]
- !!python/tuple [398, 415]
- !!python/tuple [417, 431]
- !!python/tuple [433, 453]
- !!python/tuple [455, 469]
- !!python/tuple [471, 474]
- !!python/tuple [476, 479]
186180:
- !!python/tuple [114, 116]
- !!python/tuple [118, 124]
- !!python/tuple [126, 140]
- !!python/tuple [144, 149]
- !!python/tuple [151, 170]
- !!python/tuple [173, 176]
...

or plain text:

> grl convert -f txt A.xml
---------------
RUN: 186178
LUMIBLOCKS:
  125 - 156
  158 - 161
---------------
RUN: 186179
LUMIBLOCKS:
  382 - 388
  390
  396
  398 - 415
  417 - 431
  433 - 453
  455 - 469
  471 - 474
  476 - 479
---------------
RUN: 186180
LUMIBLOCKS:
  114 - 116
  118 - 124
  126 - 140
  144 - 149
  151 - 170
  173 - 176
...

grl convert will also convert a GRL into Python code (dict of lists of tuples) or (as a joke) a ROOT TCut expression.

grl runs

grl runs simply prints the run numbers, one per line, contained within a GRL:

> grl runs A.xml
186178
186179
186180
...

Quickly print the runs contained in a GRL from a URL:

> grl runs http://atlasdqm.web.cern.ch/path/to/grl.xml
