how to convert large TDMS file (500 MB, 32 M samples - 2 channels) into one or multiple LVM file

[Manish_Keswani]

I would like to be able to read atleast 4-5 million rows of total 32 million rows data at a time. The TDMS file has data for 2 channels and no time data. If I can convert TDMS file into one or more LVM files, then I can read large LVM files using JMP software.  I am using 2009 Labview. Pls. provide suggestions.

Thanks in advance. Regards, Manish (Univ of AZ)

Hi Manish,

For your issue with getting .tdms to .lvm, take a look at this forum and this community example.  I checked it out, and I believe it should be able to work nicely for you as far as creating multiple .lvm files out of a single .tdms file.  The only thing that might be an issue is the time requirement for getting all the data into LV and saved to multiple files, but you will run into that when working with large amouts of data.

I would also like to suggest that you take a look at DIAdem if you are looking into analyzing large sets of data.  The program is built to handle large sets of data and do analyzation on the data.
