Dear SPM experts
We have done a DTI analysis and we observed the following:
1. the analysis of the whole brain revealed that the search volume is
491'187 voxels / 381.5 resels
2. when we used Small Volume Correction (SVC) and restricted the analysis to
only white matter (with WM masks from the pickatlas) the number of voxels is
decreased to 356'829, but the number of resels increased to 597.5!!!
3. then we used SVC with masks for only motor and somatosensory areas and
the number of voxels decreased to 67'062 / 238 resels
Is it a normal behaviour of RFT that the number of resels increases when the
number of voxels decreases?
Thanks in advance
Best regards
Juergen
