Hi All,
When we say FWHM 10, does that mean a circle with a radius of 10 mm ?
Yes. It is actually a 2D isotropic gaussian, so isoclines are a circle.
Also I have some significant clusters from my analysis, will the area
of the cluster be in mm2 ?
Yes.
How is the area of a significant cluster calculated ?
Summing up the area of the triangles of the vertices in the cluster.
doug
I mean the math behind it. Is it mapping the cluster to the 1mm3
volume and counting the number of voxels ? (I know I can make a label
of the cluster and run the anatomical-stats command to get the value ?
Thank you
Subha
