Hi Aaron

they are various wm.mgz voxel values that get set based on different filters/topological considerations.

Hello Freesurfers.

I was wondering of for the purposes of editing wm.mgz if changing voxel values to anything but 255 a nd 1 will be useful in anyway. If so I was wondering if you can explain to me what the following val ues mean and how do I use them.

#define THICKEN_FILL 200 #define NBHD_FILL 210 #define VENTRICLE_FILL 220 #define DIAGONAL_FILL 230 #define DEGENERATE_FILL 240 #define OFFSET_FILTER_FILL 245 #define AUTO_FILL 250 #define PRETESS_FILL 215 #define WM_EDITED_ON_VAL 255 #define WM_EDITED_OFF_VAL 1
