Issue Details

How can I read and write TDM/TDMS files with software products that are not designed by NI?


The section 'Writing and Reading TDMS Files with Third-Party Programming Software' from the NI TDMS File Format document addresses multiple tools recommended by NI to read and write to TDM/TDMS files using third-party software. These consist of the TDM C DLL the Calc and MATLAB TDM Example User Guide

In addition to those, it is possible to interface with TDM/TDMS files through TDM Excel Add-In Tool for Microsoft Excel User Guide and Notepad. In DIAdem 2018 and later, metadata is compressed by default to minimize the file size. To interface with TDM/TDMS files developed in those DIAdem versions using Notepad, make sure TDM/TDMS files metadata is not being compressed. Metadata compression settings can be found in DIAdem Settings: NAVIGATOR dialog box
