Why am I unable to import TDMS files using MATLAB Data Acquisition Toolbox R2023a?

I am attempting to import a TDMS file but following error appears:

>> data = tdmsread('MyFile.tdms')
Channel Group Property name does not exist.

What steps can I take to avoid this error?

This is a known issue with releases of the Data Acquisition Toolbox prior to R2024a, which may not be able to read some TDMS files generated with third-party tools, such as NI LabView and NI FlexLogger.

As of R2024a, calling "tdmsread" on a file like this should prompt you to use "tdmsconvert" to generate a TDMS v2.0 file that contains the same information.

You should be able to call "tdmsread" (and other functions, such as "tdmsinfo") on the TDMS v2.0 file without encountering an error.

 

Here is the documentation page for "tdmsconvert", which was introduced in the R2024a release of the Data Acquisition Toolbox:
