How to read part of the data channel from TDM storage?

[Jakub]

Hi all LabViewers,

I have stored data to TDM storage. Now I would like to read it, I am able to read whole channel, however, I would like to read just part, for example smaples between 40-60s of measurement. Can I do it with TDM or I have to switch to standard binary file?

thank you very much

best regards

Hi Jakub,

Yes, you can query TDM files for samples with certain specifications.  Take a look at this Tutorial Introduction to LabVIEW Data Storage VIs.  The section on Query Conditions demonstrates how to look for select samples using the Data Storage express VIs. 

I hope this is helpful.  Please post if you have further questions!
