View multiple TDMS files at once?

[dt1804]

We have to store data from 2 channels in 2 seperate TDMS files, but I need to view/analyze them togther.  How can I open two or more TDMS files at the same time?

Have you already tried DIAdem ?

Why don't you just write a VI that reads the files, extracts the data of interest and then displays the parts you want see together?

There is also an Excel plug-in for TDMS.  I suppose you could open two instances of Excel and compare the data that way although I've never tried it.

We used DIAdem in the past, I was just hoping not buy more addons.  I really like TDMS, but this may be the deal breaker.  Currently we use network shared variables to write to a Citadel database, so we are able to pick and choose whatever concurrent we desire.

This is probably the only solution, although I wonder how clunky it would be?

Which solution do you mean?  Diadem or rolling your own reader? 

You could code up a very nice system to read TDMS files but keep in mind that TDMS is kind of a database in itself.  If you want to store to Citadel it might be best to just write your data as a BLOB of variants.  You'd still have to code something to pull the raw data out, decode it back into the original data and dislay it though.
