Save and load multiple waveforms and data per time stamp

[JeffreyW]

First of all, my name is Jeff, I am a senior at DeVry University working on ym senior design project.

I am creating a phisiological monitor

First of all, my name is Jeff; I am a senior at DeVry University working on my senior design project.

Using Labview 8.0, I am creating a physiological monitor, I have two voltage signals running into the program, at which time I do some peak and peak-peak analysis.

I am posting because I need an example or something to help me figure out a way to program this in a manner that will allow me to save multiple waveforms and associated data to a file, and open it at a later time for statistical analysis. I’d like to have a way of to show all the time stamps and when you click on one it opens the associated waveforms and data.

 I know I am asking a lot but if anyone can just point me to some examples that will help me figure out how to obtain what I want.

The following is a lot of details incase what I have written is not explanatory enough:

1. I am using an express VI to read 2 channels from the DAQ card.
2. the output is then split into each separate waveform
3. At this point I split each channel into 2 copies each.
4. one copy of the waveform is dumped into the file(need help with this one)
5. the second copy is analyzed using peak and peak to peak detection and dumped into a file(again still need help with this one)
6. What I want to be able to do is load all this data in a way that I can perform some statistical analysis.

attached is a copy of my current labview program so you can have an idea of where I am at now.

Hi JeffreyW,

To log data, I would recommend using the Write to Measurement File Express VI.  If you would like to log a couple of signals to one file, just use a Merge Signals VI before inputting the data to the Write to Measurement File Express VI.

The data from the Write to Measurement File can be opened using Excel.  When you configure this express VI, you can even save the file with a .xls extension if you would like.

Please give this a try, and let me know if you have any further questions.  Best of luck on your senior design project, and have a wonderful day!!
