Mixing types within a dataset is the sort of thing that can
really confuse programs. I do not know of specific cases where
it would be a problem, but I expect that there are some.

Let me address your other questions before continuing.

- If there are too many sub-brick labels to dislpay on the
screen, then instead or left-clicking on the label to change
it, try right-clicking on the text to its left (e.g. 'Olay').
That should give you a scroll menu.

- The command-line tool to get information about the sub-bricks
is '3dinfo'. That matches the misc->Olay Info, say. You would
probably want to run it with the -verb option, to display more
than just the first few sub-bricks.

Regarding this, I highly suggest keeping the sub-bricks in the
same positions. Sub-brick 24 should always mean the same thing,
or your scripting life gets very difficult.

If your original 3dDeconvolve command was run with float, then
maybe you are better off re-running the first 5 (and everything
afterwards) with -float.

...which brings us to your subject question... :)

You can undo the 3dDeconvolve simply by removing the newly
added sub-bricks from last time. Be very careful to remove the
correct ones, but it should work.

For example, if you started with 20 sub-bricks and ended up with
26 after using -xrestore, then remove those last 6 with 3dbucket.
Start with renaming (moving) the original dataset, and then using
3dinfo to verify the sub-bricks.

3drename stats.all stats.26
3dinfo -verb stats.26+orig
3dbucket -prefix stats.all stats.26+orig

3dDeconvolve -xrestore ... -bucket stats.20

That should work.
