Delete single TDMS Channel from an existing TDMS File

[laurentp]

Overview

The example demonstrates how to delete a channel from a TDMS file.

Description

Since there is no possibility to directly delete a channel from a TDMS file with LabVIEW. This example therefore converts the TDMS file to a TDM file and performs the changes and converts the TDM file back to a TDMS file.

Requirements

 Software

• LabVIEW 2012 Base Development System (or compatible)

 Hardware

• No hardware is necessary to use this example VI

Steps to Implement or Execute Code

1. Open the attached file
2. Select the path of the TDMS file (an example file can be found in the same directory as the VI)
3. Specify the channel and group name
4. Run the VI
5. (if no error occurred) Close the TDMS File Viewer to finish the execution of the VI

The VI increased the amount of properties of the channel group.

There should be a way to just delete a TDMS channel without affecting the properties of the channel group.

the example creates extra properties, i.e. register 0, etc.  and it screw up files that have non-NI properties in the channels.  we have special properties in the channels to help convert data from raw to EU, after using this vi to delete a channel we were no longer able to display the data properly.  Good idea but it is properly better to write your own.
