Hi all,
I'm trying to use atlasquery using the option -m, where I place a mask image where my activations are. The command line I'm using is:
"atlasquery -a "MNI Structural Atlas" -m feat_mask.nii >> locations.txt"
Results are:
---------------------------------------------------------------------------------
Using atlas: MNI Structural Atlas
Working from mask : feat_mask_FA_C_EA_fastsym_45_99dot5.nii
0
Caudate:10.1344
1
Cerebellum:0.095793
2
Frontal Lobe:2.17663
3
Insula:4.36143
4
Occipital Lobe:1.45434
5
Parietal Lobe:2.13323
6
Putamen:0.120506
7
Temporal Lobe:1.05662
8
Thalamus:0.770808
---------------------------------------------------------------------------
Is this correct? If I understood, if the atlas is a label atlas, then the value is the overlap percentage (between 0 and 100). My question is, why all these percentages do not sum 100?
If my mask is registered to MNI but it is in 1.5x1.5x1.5mm. Do I need to transform it to 1x1x1mm?
Thanks in advance,
Maite
