I managed to create a Python script running inside DIAdem (using the DIAdem lib) that decimates SystemLink tdms files. The (very large) SystemLink database consists exclusively of tdms files generated by cRIOs. The generated decimated file names, the "Root Name" and the "channel names" matches the original SystemLink files (see attached document with before and after decimation screen shots). Notably the number of channels are the same, however the script (using ChnResampleFreqBased()) creates so called "Implicit" channels. The metadata tab also contains addition info after the decimation.
Question: Is it safe to overwrite the original tdms files with these newly generated decimated files without corrupting the database?
