Dear SPM'ers,
I was wondering wheteher any of you could help ( actually i'm sure you all can
this question is so basic!), i am a bit new to all this so please excuse my
ignorance! what I would like to know is as follows
when I smooth I put in 3 values e.g 5.8 5.8 7.5. Thses values that i put in ,
are they the the width of the gaussian filter or does spm do somthing to the
values giving me a different width
also when you get your functional map , you can get a list of coordinated which
correspond to activated voxels , at the bottom though it gives you the voxels
per cluster , does this mean that the time course derived from the voxel is an
average of the number of voxels per cluster or does the coordinate represent the
voxel of highest intensity
please help!
