Hi Serge,

read your LVM file and save it using TDMS functions?

I think that is going to depend on how your LVM file is formatted. The writing to TDMS is quite straight forward and just use the TDMS Write function giving it the proper data, channel and group names.

Reading the LVM shouldn't be hard, just understanding the pieces. I think LVM is just a text file with some header information, then tab delimited data. Read all the data, turn it into arrays, then write to TDMS.

Post an example LVM file and code if you get stuck.

I asked you first You're not giving us much information, so any answer we give you is probably going to be incomplete or may not work in your situation. For best results, give us all of the information you can.

Yes, you are right Hooovahh,

I'm attaching a sample fLVM file, I use to acquire 1 second at 48KS/sec, so basically my file contains 48,000 points, what I'd like to do is to convert it to TDMS, but i do not really have an idea on how to do that

Thanks for your inputs

As much as I hate express VIs, it sure made quick work of what you wanted.
