merge files with different sampling rates

[AndreasH_Ha]

Hello Roooky,

to map from one frequency to another please use "CHNMAPLINCALC". This function allows you to define one pair of channels (x/y) as source and another x-channel to define the time values your source should be mapped to.

If you want to load a sequence of file, please use "DATAFILELOAD".

Your sequence woud be probably something like

DataDelAll() ' make sure everything is saved

Your sequence woud be probably something like

- DataDelAll() ' make sure everything is saved before you call DataDelAll

- DataFileLoad(...) Load the file you want to process

- Generate/load a time channel with your target timing

- Using CHNMAPLINCALC loop over all channels to map to teh target timing

- Save the data back to file

Let me know if you have questions

Hi Andreas,
thanks a lot for your help, I will try to do it this way and let you know wether it was succesfull...

I have a simiilar situation ...

I have 2 TDMS files with data at different sampling rates.  The low-speed data file has a timestamp channel plus waveform data channels.  The high-speed data file has only waveform data channels.  I'd like to merge the timestamp channel plus 2 low-speed waveform data channels with the high-speed data file.  Then I want to graph everything with time on the x-axis.  I'm not sure how the previous functions help me.  Is this something to be done via scripts or should I write something in LabVIEW?
