Dear SPM users,
I am having a fundamental doubt. I am
assuming that the beta values of different
co-ordinates can be obtained by displaying the
corresponding "beta images" in mricro.
But if the cursor is placed in the CSF
region, negative values are shown - the magnitudes are
comparable with that of active voxels. Actually the
beta values of CSF should be zero or nearer to zero.
So,this confuses me. please clarify the same.
With thanks
