Hi Rick

Thanks for getting back to me. Voxel size in the stats dataset looks to be consistent with this (see 1). I've also pasted the out.ss.. file (see 2).

So do you think the lengthy processing speed is to with this size of grid? Any suggestions as to how I can speed things up and get going with this analysis would be great.
