Welcome to pyEvalData¶
This is a Python module to read and evaluate experimental data. It can handle raw data from different sources such as spec, hdf5, NeXus files which are common data formats at synchrotrons, FELs, as well as in a growing number of laboratories. The evaluation provides common functionalities such as binning, error calculation, and advanced data manipulation via algebraic expressions as well as pre- and post-data-filters. Furthermore, advanced wrapper functions allow for plotting and fitting sequences of one or multiple scans in dependence of an external parameter.
A minimal code example would look like this:
import pyEvalData as ped # define your data source spec = ped.io.Spec(file_name='data.spec') # initialize the evaluation ev = ped.Evaluation(spec) # define the x- and y-data ev.xcol = 'motor1' ev.clist = ['ct1', 'ct2', 'ct1/ct2'] # create a plot for scans 1-3 ev.plot_scans([1, 2, 3])
reading of several pre-defined raw data formats
easy implementation of new raw-data formats using an
common methods for plotting and fitting of experimental data, including:
data manipulation via algebraic expressions
common data pre- and post-filters
You can either install directly from pypi.org using the command
$ pip install pyEvalData
or if you want to work on the latest develop release you can clone
pyEvalData from the main git repository:
$ git clone https://github.com/dschick/pyEvalData.git pyEvalData
To work in editable mode (source is only linked but not copied to the python site-packages), just do:
$ pip install -e ./pyEvalData
Or to do a normal install with
$ pip install ./pyEvalData
Optionally, you can also let pip install directly from the repository:
$ pip install git+https://github.com/dschick/pyEvalData.git
You can have the following optional installations to enable unit tests, as well as building the documentation:
$ pip install pyEvalData[testing] $ pip install pyEvalData[documentation]
