YODA Python-interface documentation!

This is the documentation for the Python interface to the YODA data analysis package. It’s rather bare-bones at the moment, and based largely on the docstrings embedded in the Python code. So the documentation you see here is the same as the documentation you can get by calling pydoc or by using the help() function in the Python interpreter, e.g.:

$ python
>>> import yoda
>>> help(yoda.read)
>>> help(yoda.Histo1D)

As time goes by we’ll fill this documentation out with more examples etc. – at least that’s the plan. Feel free to hassle the authors at yoda@projects.hepforge.org if we don’t do it, or if you find things we can improve either in the documentation or the package itself.

Scripts

TODO: the set of yoda* scripts needs to be documented here. For now, you can find out how to use them by calling e.g. yodafoo –help. Here is the current list of scripts that you can try:

yoda-config
yodals
yodacnv
yodadiff
yodamerge
yodascale
yodastack
yoda2yoda
yoda2root
root2yoda
(yodaplot)

Code docs

Basic usage

• Booking and filling a histogram called ‘/foo’ with 20 bins between 0 and 1:

  import yoda, random
  h = yoda.Histo1D(20, 0.0, 1.0, "/foo")
  print (h)
  => <BinnedHisto1D[d] '/foo' 20 bins>
  for _ in range(1000):
      h.fill(random.uniform(-0.5, 1.5))
  print (h.xMean())
  => 0.5217243567375633
  

• Extracting histogram statistical properties:

  ## Binned range extent:
  print (h.xMin(), h.xMax())
  => 0.0 1.0
  
  ## Sum-of-weights / integral for whole-range and binned-range only:
  print (h.sumW(), h.sumW(False))
  => 1000.0 525.0
  
  ## All-range and binned-range whole-histo stats:
  print (h.xMean(), h.xStdDev(), h.xVariance())
  => 0.5217243567375633 0.5590492850512596 0.31253610311632457
  print (h.xMean(False), h.xStdDev(False), h.xVariance(False))
  => 0.5200949573114909 0.2895440742052287 0.083835770907363
  

• Extracting bin properties:

  ## Looping over bins:
  for b in h.bins():
      print (b)
  => <Dbn1D(mean=0, stddev=0.05)>
  => <Dbn1D(mean=0.05, stddev=0.1)>
  => <Dbn1D(mean=0.1, stddev=0.15)>
  => ...
  
  ## Extract
  for b in h.bins():
      print (b.xMin(), b.xMid(), b.xMax(), b.xFocus(), b.sumW2(), b.xMean(), b.xStdDev())
  => 0.0 0.025 0.05 0.0277156583946 19.0 0.0277156583946 0.0156189244522
  => 0.05 0.075 0.1 0.077004858171 22.0 0.077004858171 0.0160044669375
  => 0.1 0.125 0.15 0.124272408837 32.0 0.124272408837 0.01703599909
  => ...
  

• Saving to file, and reading back:

  ## Saving
  yoda.write(h, "foo.yoda") #< can pass any iterable of histos or other analysis objects
  
  ## Reading to a dict, indexed by histo paths
  aos = yoda.read("foo.yoda")
  print (aos)
  => {'/foo': <Histo1D '/foo' 20 bins, sumw=1e+03, xmean=4.84e-01>}
  
  ## Reading to a list
  aos = yoda.read("foo.yoda", asdict=False)
  print (aos)
  => [<Histo1D '/foo' 20 bins, sumw=1e+03, xmean=4.84e-01>]
  print (aos[0].path())
  => /foo
  

• Converting to a Scatter, and looping over points:

  s = h.mkScatter()  # <- you may also read scatters from file, e.g. reference data
  print (s)
  => <Scatter2D '/foo' 20 points>
  
  for p in s.points():
      print (p.x(), p.y(), p.xErrs(), p.yErrAvg(), p.errAvg(2))
  => 0.025 380.0 (0.025, 0.025) 87.1779788708
  => 0.075 440.0 (0.02500000000000001, 0.024999999999999994) 93.8083151965
  => ...
  

• Analysis object metadata:

  print (s.annotations())
  => ['Path', 'Title', 'Type']
  s.setAnnotation("Foo", "My own private Patrick Swayze")
  print (s.annotations())
  => ['Foo', 'Path', 'Title', 'Type']
  print (s.annotation("Foo"))
  => 'My own private Patrick Swayze'
  

Tips and tricks

• Filtering analysis objects by path:

  aos = yoda.read("mydata.yoda")
  hs = [h for h in aos.values() if "foo" in h.path()]
  

  or, if you have YODA version >= 1.3.2, you can do regex filtering inline during analysis object reading from file:

  aos = yoda.read("mydata.yoda", ".*foo.*")
  

• Summing histograms:

  import operator
  hsum = reduce(operator.add, hs)
  

Bin/point path searching

The yoda.search subpackage provides tools for finding histogram bins and scatter points based on their parent objects’ paths, and on the bin/point index or the physical location of bin edges.

class yoda.search.PointMatcher(patt)

System for selecting subsets of bins based on a search range syntax extended from Professor weight files:

Path structures:

• /path/parts/to/histo[syst_variation]@xmin:xmax

• /path/parts/to/histo[syst_variation]#nmin:nmax

TODO: Extend to multi-dimensional ranges i.e. @xmin:xmax,#nymin:nymax,…

match_pos(p)

Decide if a given point p is in the match range.

p must be an object with attrs xmin, xmax, n

TODO: Use open ranges to include underflow and overflow

TODO: Allow negative indices in Python style, and use index=-1 to mean the N+1 index needed to include the last bin without picking up the overflow, too.

TODO: Extension to multiple dimensions

set_patt(patt)

Find path and index/pos parts of patt and assign them to object attrs

yoda.search.match_aos(aos, patts, unpatts=None, search=False)

Filter a list of analysis objects to those which match given path-matching patterns.

@a patts is a regex or iterable of regexes for positive matching, i.e. retention; @a unpatts is the equivalent for negative matching, i.e. rejection even if a patt matches.

@a search will use Python regex search mode rather than match mode, i.e. match if any part of the path fits the regex, rather than requiring a match from the start of the path.

Histogram plotting

The yoda.plotting module provides in-development tools for conveniently comparing and plotting YODA objects using matplotlib.

Miscellaneous

Other functionality in the yoda package…

yoda.script_helpers.filter_aos(aos, match_re=None, unmatch_re=None)

Remove unwanted analysis objects from a dict (modifies arg, also returned)

yoda.script_helpers.parse_x2y_args(args, xextns, yextns)

Helper function for working out input and output filenames for YODA converter scripts, where the output name is generated by replacing the input file extension (xextn) with the output one (yextn), if there are exactly two arguments and the second arg is consistent with an output name. The x/yextn arguments should include the leading dot.

Main YODA objects

The wrappers on the core C++ YODA data types and functions are all defined in the yoda.core module, which is generated semi-automatically by the Cython system. However, they are all available directly in the yoda namespace by virtue of a from yoda.core import * in the yoda package.
