Hi Julius,
How are the images stored, 1 slice per file, or
22 slices per file? If the answer is 22, then I
would suggest using file_tool again, to break
up the file and re-format it.
If each file holds one slice, then you should
probably write a shell script to count to 22,
moving files around in a loop (save a backup of
everything first :).
Another option is to just put them together with
to3d, and then use 3dzcat on them afterwards.
