Sir,

I couldnot apply any 'TT_Daemon::amygdala' like form with our mask.

I meant ,our mask is All_Mani_ROIandIFG.333_short+tlrc and I can't apply 'All_Mani_ROIandIFG.333_short+tlrc::amygdala' on it.

I have approached another way to this problem.

3dROIstats -mask All_Mani_ROIandIFG.333_short+tlrc -nzvoxels -nzminmax -nzmedian -nzmean All_Mani_ROIandIFG.333_short+tlrc

Means I applied the same mask itself on it. Then I got result like this.

Location NZCount
61 85
62 89
63 13
64 17
65 838
66 877
67 682
68 695
69 147
70 113
71 310
72 256
73 735
74 798
Total 5655

Same time, I found that
3dBrickStat -count -non-zero All_Mani_ROIandIFG.333_short+tlrc is giving me 5655 as total voxel count.

Is it correct? A reply will be greatly appreciated.

Thanks,
Binu
