Description¶

The algorithm SaveMDWorkspaceToVTK will write an IMDHistoWorkspace or IMDEventWorkspace to either a .vts or .vtu file, respectively.This file can be directly loaded into a standalone ParaView application.

To make use of all stored out features, such as axes annotations, it is required to load the NonOrthogonalSource plugin. To set this plugin navigate to Tools > Manage Plugins and open the Plugin Manager. Enable the Auto Load option on the and press Load Selected.

Note that it is currently not possible to save out workspaces with more than three dimensions.

Usage¶

import os
signalInput = [i for i in range(1,28)]
errorInput = [1 for i in range(1,28)]

ws = CreateMDHistoWorkspace(SignalInput=signalInput, ErrorInput=errorInput, Dimensionality='3',
                            Extents='-1,1,-1,1,-1,1', NumberOfBins='3,3,3', Names='A,B,C', Units='U,T,W')

ws2 = CreateMDHistoWorkspace(SignalInput='1,2,3,4,5,6,7,8,9', ErrorInput='1,1,1,1,1,1,1,1,1', Dimensionality='2',
                            Extents='-1,1,-1,1', NumberOfBins='3,3', Names='A,B', Units='U,T')

savefile = os.path.join(config["defaultsave.directory"], "mdhws.vts")
SaveMDWorkspaceToVTK(InputWorkspace = ws, Filename = savefile)

print("File created: {}".format(os.path.exists(savefile)))
