+# -tr: Total ROI to process. It is a list of 3 elements, each one is a list with the start and end of the ROI in the x, y and z axis respectively.

+# -rr: ROI to read. It is a list of 3 elements, each one is a list with the start and end of the ROI in the x, y and z axis respectively.
+# -wr: ROI to write. It is a list of 3 elements, each one is a list with the start and end of the ROI in the x, y and z axis respectively.
+# -nw: Number of workers to use.
+# -ic: Input container. It is the path to the input zarr file.
+# -id: Input dataset. It is the path to the input dataset inside the input zarr file.
+# -oc: Output container. It is the path to the output zarr file.
+# -od: Output dataset. It is the path to the output dataset inside the output zarr file.
