Thanks,
I need to modify my question; creating several thousands of correlation arrays might not be the best solution. Instead I would want to calculate the correlations one at a time, the main point being that I need to go through all possible paircombinations while writing the result to some new array (that can be interpreted afterwards). My immediate thought is som form of nested loop.. How can one scroll through all combinations in a Group?
Thanks
