Iterate over a value in a sequence batch file, save results each time

[Nicoco]

Hello all,

Is it possible to iterate over a value in sequence batch file, pass this value to a block, and save results at every iteration?

An image being worth a thousand words, here's one:

I'm pretty happy with my protocol, except that I'd like to test a wide range of Th. scale 2 (center of my image, set to 63) values for the spot detector. Right now, I'm increasing the value manually, but I'm wondering if there's a way to automate this. I have taken a look at Iterator and Range loop blocks, but it seems there is no way to iterate both on the images and on the values.

Am I wrong?
