Is LabVIEW able to record the peak to peak value from an ECG wave automatically?

i have encounted a problem!! i need help plz >.< i gt the error 20013 saying Analysis: The width must meet: 0 < width < samples. wat is going on? i tried to change the width setting but the same error still occurs. heres my vi

Why are you taking an array control called "Number found" and turning that into a Dynamic Data Type that you are merging with the signals coming from your File Read Express VI?  I suspect that is causing your problem since that array is empty.

thanx!! but i gt another problem. the program i make it cant record the peak value. did i make some mistake?

[RavensFan]

I have no idea.  You haven't posted your latest version of your VI.  The one you showed before doesn't show any attempt at recording a peak.

PS.  Please don't use "text speak".  Also please try to capitalize your sentences so that they are more readable.

Sry abt the cap thing. Here my new VI. I dont know what is the error occuring. What do they mean by 1D array?. If thats not the correct way to record the file than how am i suppose to program it so that is it able to record all the peak point from my waveform.Thanx for helping me!

Now you just need to stop with the text speak.  "sry abt" means nothing.

Have you taken LabVIEW tutorials?

LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

The cluster coming out of the peak VI is a 1-D array of clusters.  The cluster called "Locations" consists of 1-element, a 1-D array of doubles.  You need to get down to that 1-D array.

I have a few question. Why i still cant read the peak of my waveform when i am already using the peak detector function? When i run the file and i open the text file which i store all the recording inside, i still see all the values but not the peak. Need some guidance with the function.

I have done a new iv but this new iv only allow me to read the peak value. Is there anyway than i can program it so that i can read both the peak and the valley of the graph accurately?

[RavensFan]

Put another Peak detector in so it acts on the same array in parallel, but set the input constant to be Valleys instead of Peaks.

[GG_Jialat]

I have done changes to my VI. After the changes i was able to read the valley value but due to noise i wasnt able to correctly locate the correct valley. Is there any filter that i could use to remove noise in the waveform without affecting much of my reading?
