Hi Andrés,

> is there a way to reassemble the 4x4 tile without FFT and data jumbling?

The Stitching plugin is one decent way to go. That plugin has two steps,
overlap computation and fusion; my understanding is that Fourier space is
only used for the overlap computation step. The plugin has a "compute
overlap" option you can uncheck to skip that in favor of using coordinates
provided from elsewhere (typically a TileConfiguration.txt file).

But given that you have exactly zero overlap, even that fusion step is
overkill. You might be better served by:

- Creating the new full size image as a blank
- Using ImageJ's copy & paste functionality to paste each tile onto the
proper position of the big image

Unfortunately, I couldn't see a function to control where the paste happens
(it is centered by default). The low-level API is there to do it somewhere
else, though it would take some digging in the IJ1 code [1] to figure it
out.

Regards,
Curtis
