How does Labview stores the binary data - The header, where the actual data starts etc.

[Bicknell55]

I downloaded the one that was written in LabVIEW 7.1.  When I go to open the vi I get a 'load error code 9: VI version (7.1) is newer than LabVIEW version (7.0).  I'm unable to open the vi files because I have an older version.

Hello,

Please see the attached .zip file. It contains the Write MAT file VI saved in LabVIEW 7.0.

Hello:

This maybe some handling issue I am not aware of but recently when doing signal processing from digitized recorded ECG signals I could'nt figure out how and why I am getting amplitudes as high in the 10E9 orders! While the general waveform is correct the magnitudes are not. I have also tried to divided out or rescale the data but it simply zeros out all the values when I perform the operation? How is this? What can be done?

Thanks for any tips.

Not to bring up an old thread, but is there anyway I can increase the number of inputs from 2D?  I'd like to increase it up to 5 so I end up with 5 columns of data.  I'm not really sure how to go about it. 

Thanks

Brent,

It seems the only modification you would need to make to the previously posted VI would be to expand the Build Array function for 4 more inputs and add your extra "columns of data" there. In case you are unfamiliar, the Build Array function is the one located directly to the right of the labels "<time>" and "<data points>" on the block diagram. You can simply strech the function downward to create more inputs.

Hope this gets you pointed in the right direction!
