Hi, I prepared code for multichannel by using COMM4, and now I am stuck in getting data from the condition loop and while loop. As I tried to get it within a while loop it is giving "To save file" after every iteration and also overwriting it means when I stopped the code to check file it gave only one row of data points.kindly please guide Hasham

Hi Hasham, @Hasham622x wrote: Sorry to disturb you again I prepared avarage part in code but it is giving random/rong values. Kindly please guide where I am doing mistake. Placing the averaging code inside the while loop is nonsense as your 2D array consists of just one row of data (and so only one element per column)! Placing the averaging after the while loop looks better and should do what you asked for. Unfortunately we still cannot debug/edit/run images in LabVIEW, so you need to debug on your own! Suggestion: Place the averaging code in a subVI, with a 2D array input and a 1D array output. Run your mainVI, have the subVI open while running. After stopping the mainVI you set all values in your subVI as default and save the subVI. Attach the subVI so we can debug it… Btw. what's your problem with creating block diagrams with straight wires? Ever heard of LabVIEW Style Guide?

Hi Hasham, @Hasham622x wrote: I tried to run by implementing the guidance you provided Why do you need 3 ExpressVIs when I suggested to use a FOR loop and a (simple) Mean function??? What's wrong with my suggestion? I repeat: "Transpose the array, autoindex the rows in a FOR loop and use the mean function inside the loop…"
