Module for loading, interpolating and plotting data taken at the SGM Beamline at the Canadian Light Source.

Project description

Helper module for working with data from the SGM Beamline

Installation:

Using pip:

pip install sgm-data

or from source:

git clone https://github.lightsource.ca/arthurz/sgmdata ./sgmdata
cd sgmdata
python setup.py install

Usage:

First import the package, and select data to load in.

import sgmdata 
data = sgmdata.SGMData(["file1.hdf5", "file2.hdf5", "..."])

This will identify the independent axis, signals and other data within the files listed. The file load list also works with hsds domains.

data = sgmdata.SGMData(["file1.data.sgm-hdf5.lightsource.ca", "..."])

Useful functions:

data.scans  #contains a dictionary of the identified data arrays loaded from your file list
data.interpolate(start=270, stop=2000, resolution=0.5) #bin the data in scans dictionary and interpolates missing points
data.mean() #average data with the same sample name, and spec command together. 

Working with individual scans:

df = data.scans['FilePrefix'].entry1.interpolate(start=270, stop=2000, resolution=0.1) #bin data for a single scan.
df2 = data.scans['FilePrefix'].entry1.fit_mcas() #perform batch gaussian fitting of interpolated SDD signal

Plotting (with Bokeh):

data.scans['FilePrefix'].entry1.plot()
data.average.plot()
