Well then you're doing something wrong, or there is something that you 
haven't told us.

E.g.:
> junk <- array(runif(64*128*95),dim=c(64,128,95))
> junk.chopped <- junk[,,1:90]
> dim(junk)
> [1]  64 128  95

Perhaps Model.4 has some structure other than that of an array. 
(Originally you said it was a matrix.)

You really need to get your terminology and ideas *clear* in order to 
have any hope of receiving useful advice.

I have no idea what you are on about in respect of "the number of 
cells".  My mind-reading machine is in the repair shop.  I strongly 
suspect that your thoughts are confused.

cheers,

Rolf
