Description

Loads the given file, which should be in the CanSAS1d format specified by canSAS 1D Data Formats Working Group schema http://svn.smallangles.net/svn/canSAS/1dwg/trunk/cansas1d.xsd and creates output workspace. CANSAS has a Wiki page at http://www.smallangles.net/wgwiki/index.php/canSAS_Working_Groups

If the file contains multiple SASentry elements a workspace group will be created and each SASentry will be one workspace in the group. Loading multiple SASdata elements is not supported.

Usage

Example - Save/Load “Roundtrip”

import os

# Create dummy workspace.
dataX = [0,1,2,3]
dataY = [9,5,7]
out_ws = CreateWorkspace(dataX, dataY, UnitX="MomentumTransfer")

file_path = os.path.join(config["defaultsave.directory"], "canSASData.xml")

# Do a "roundtrip" of the data.
SaveCanSAS1D(out_ws, file_path, Version=1)
in_ws = LoadCanSAS1D(file_path, Version=1)

print("Contents of the file = {}.".format(in_ws.readY(0)))

Output:

Contents of the file = [ 9.  5.  7.].
