"inhomogenous arrays" error when writing to matfile was caused by numpy version (we were at version 1.24.4, recommendations is numpy>=1.13.0, < 1.24). Reverting to numpy 1.23.5 resovled the error. Solution is to save to RAM instead of to a temp matfile, making the process independent of numpy versions.
removed the one layer case added on 08.09.2026 again.
Added a special case to deal with stacks that only have one z layer.
ROI_fissa could not handle stacks that only had one z-layer (Fissa worked fine, bug was relating to export_to_matfile).
