problem with data flow

[parag77]

HI 

I am facing problem in understanding data flow in labview.I am using while loop inside two for loop,but my program is  ending up in infinite loops .

I have attache my VI below .

I will thankful for your help

How do you know you have infinite loops?

In frame 2 of your flat sequence structure, I see a while loop that will run as fast as it can until i=359,  so 360 iterations.

In frame 3, another while loop that will run 360 iterations.   It is inside a 64 iteration For Loop and that inside another 64 iteration For Loop.  I don't see anything that would cause infinite loops.  That while loop will run a total fo 64 x 64 x 360 iterations,  1,474,560.  That is a lot, but is certainly not infinite.  I don't know how long that code will take to run, but I don't see anything in there that is particularly time consuming.

I suggest you put indicators on all of your iteration nodes and confirm that loops are running infinite times.

Thank you for your brisk reply ...

I am using large data set that's why It is taking time .I did mistake in probing while crossvalidating .

If it's taking a long time that it feels like the code is hanging, then using the i terminal to drive a progress bar might be helpful,

Wow... this is good way to track progress I never used it .

Thank you
