Export a Datafield

Save in various formats

A Datafield can be saved in various data formats through the BornAgain Python method

import bornagain as ba
simulation = ...
result = simulation.simulate()
ba.IOFactory.writeDatafield(result, file_name)

where file_name must have one of the extensions

  • .txt — ASCII file with 2D array [nrow][ncol], layout as in NumPy,
  • .int — BornAgain internal ASCII format,
  • .tif — 32-bits TIFF file,

to which one may append a second extension that specifies compression:

  • .gz,
  • .bz2.

Export to NumPy

To extract data from Datafield in form of NumPy arrays, use

result = simulation.simulate()
arr_x  = result.xCenters()  # centers of x bins
arr_i  = result.dataArray() # intensities
arr_di = result.errors()    # error estimates thereof

To save any such array, use the NumPy method

numpy.savetxt("intensity.txt", arr)
