Hello Ex-jobb,
have a look at my example. I included a second way to build your array of cluster.
The string generation at the left of the diagram is to simulate your text file reading, it also gives you an array of strings.
This array is in the upper part converted by using autoindexing of an for-loop. In the lower part I used just an "Index Array" with
"Build cluster" and "build array".
Hope this helps,
GerdW
Best regards,
