I think whats happening is ReadListBinary is putting {} around
your data which is alread a list. Try seeing what the Dimensions[data]
gives you. it might be something like {1,32,32} (if you file contains a
32X32 array). This might cause data to be atomic (ie be a list of one
element (your array) rather than simply your array). if this is the case,
Flatten[data,1] will fix this.
Or this might not be the problem, although it sounds familiar.
