Dealing with large TDMS file

[DBase]

I have acquired acceleration data in signal express. Since very large sample has been stored. the file size of TDMS from 160MB to 350 MB.

I have problem in analysing the same. In signal express I have to export the TDMS to text file and then it has to be loaded back in SE for anlysis. when I attempted it, text file became so big and it is very tough to use them in SE.

I tried developing LabVIEW program to analyse TDMS directly. But still since it is a very large data. analysing became very tough. is anybody have dealt with this earlier?

Thanks

What do you mean by "tough"? Problems writing the code? Performance problems?

Hello M.S.,

Thanks for your Post! 

If I understand you correctly, you are using both Signal Express and LabVIEW to attempt to read in a very large TDMS/text file that you have previously created but you are experiencing some problems.  As Herbert asked, could you clarify the types of issues you are having? 

For now, going on the assumption that by "tough" you mean that performance is decreased, one possible cause for this when doing File I/O is the use of loops when opening, reading from, and closing a file.  If you are opening and closing the file during each iteration of the loop, this could be a source of your decreased performance.

I look forward to your future post(s)!
