 The parameter `Border width` allows to extend the requirement for the cells to be considered as fully inside. Cells that have at least one pixel at a distance less than `Border width` pixels from the image limits will be removed.

+## Sanity check
+
+**This option performs several checks to ensure that the files follows EpiCure's standards and can fix some errors.**
+
+For example, the tracks must not have frame gaps (missing one frame). If that happens, the `sanity check` option will detect it and fix it by splitting the gap in two different gaps.
+If some napari layers had been wrongly closed, this step will also re-open them.
+It also checks if the labels seemed ok or if something is weird.
