LVM to Waveform

[Akaash_Dragon]

Hello,

I have seen a similar question which was posted in 2008, but I was unable to understand the solution.

I had collected some data from an experiment through LabVIEW 2014. The data  was in the form of waveform. Each waveform had 20000 samples and there are several waveforms. The data was saved in LVM format. Now I had copied the LVM files to a different computer, which has LabVIEW 2017. However I am unable to open the LVM file through LabVIEW, and it works only with excel or wordpad.

I want to reconstruct the waveform from the LVM files. Is that possible?

Also I want to perform the following operation: Square each of the 20000 samples and add them together and then take its logarithm. Is this possible after I have opened the LVM file as a waveform in LabVIEW?

 Would be really glad if someone could explain it simple terms since I am just a beginner.

Thanks in Advance.

Have you tried this VI?

If you can´t open LVM no problem. Labview allows you to open the EXCEL Files and read the data from the file.

The data from the files can be read as a 2D array (Rows, Columns).

Using array functions you can select the data you need and represent it. 

Good luck.

Thanks a lot, but I was able to open it with the "read from measurement" block .
