Hi Giovanni,
You should be able to use a bucket dataset with 3dDeconvolve.
But the most simple solution may be to create your even/odd
datasets with 3dTcat, instead.
So to get the evens, for instance:
set evens = ( `count -digits 1 0 59 2` )
set nums = ( `echo $evens| sed 's/ /,/g'` )
3dTcat -prefix evens all+orig'['$nums']'
To get the odds, just change the 0 in the count command to 1,
and the 3dTcat prefix to odds.
Try "echo $evens" or "echo $nums" to see which subbricks you
are asking for. And "3dinfo evens+orig" should also hint where
the sub-bricks came from.
