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)))
