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.
