Hello SPM experts I am kind of frustrated for last few days, I could not get it to work the normalization issues, When I ran some basic analysis (t test), it gave a nice results for activation using other softwares, I wanted to run this with spm, it gave this problem (snapshot attached). When I run normalization for this rat brain, meanfunctional image after normalization is reduced (smaller), I did not know why. I tried changing voxel sizes of mean functional to larger, still did not work. The voxel size of rat brain image ( mean functional) before normalization is 1 x 1 x 6 ( 128 x 128 x 12) For template is 1 x 1 x 1,(80x 60 x 108). Could you please suggest me some input in this regard, I will really appreciate.

You can easily download the data files from here: http://www.fil.ion.ucl.ac.uk/spm/data/auditory/ The good way of reading and learning is to follow the instructions step by step in the analysis of those data. Of course, you spend some time, but this gives you an idea of how you should treat your own data. At least for myself it worked perfectly well!
