Replace a 2D Array in Original Array

[wasabi22]

I read N rows at a time from a file and I would like to replace a 2D array(Spike template) in original 

array only in specific index read from a spike list index.

Hi wasabi,

why do you need a while loop?

[wasabi22]

because I need to read N rows at a time. For example, if I choose N = 100

I should replace the spike template from the 10-th to

19-th line of the first 100 rows of the original array, then I should replace the spike template from 

160-th to 169-th of other 100 rpws of original array (from 100-th to 200-th row).

i hope it is clear.

(This is a continuation of this thread. )

Your VI will not work. All that you're doing is replacing a subset in the current chunk, which gets thrown away in the next iteration of the loop. You are STILL ignoring the pre-allocation method I showed you in your original thread. I have no idea why you keep doing this.

I've tried this solution in my complete vi. It is attached. I read only N rows at a time, manipulate data and generate by using not allow regeneration. 

All this to avoid memory full. I have tried with file of 170 MB and work fine

Now i want to replace a spike template(2D array) in specific index read from Spike list Index.

I'm sorry, but I have no idea what this means.

General code comments:

• Instead of using for-loops to create initializiation arrays, use Initialize Array function.
  For example, this:
  
  becomes this:
  
• Do not insert extra blank spaces and new lines in enum values. If you want to format a list selection for a top-level VI, then use a different control at the top-level. Enum values should not have linefeeds and extra spaces just so they line up neatly when the text is centered.

Thank you very much for helps and advice. 
I will try to explain better. 
I want to make a new [(File lenght)*9] 2D array where i want to substitute a 10*9 2D Array (called Spike template) in Original Array (that i read from file I01.txt).
I would like to substituite this 2D array(called Spike template) starting from specific indexes.
This indexes are 10, 160, 2152, 2628......

So i would like a new array where first 9 elements is the same of original array. Then from 10-th to 19-th there

is 2D array(called Spike template) and then from 10-th to 159-th the same items of original array and then from 160-th to 169-th there is 2D array(called Spike template) and so also for other indexes until the file ends.

I hope it is clear enough.
Sorry for my bad english.

I've attached vi and txt file in previous posts.
