This will take the mri_surfcluster annotation output and map it into a
volume in MNI152 space. Each voxel will have an integer value indicating
which cluster it belongs to. This is better than trying to work with the
coordinates. Note you can also specify a label instead of an annotation.

Hi,
I'd like to extract %BOLD-change from clusters or highly activated voxels
(first level fMRI data processed in FEAT, higher level done with
mri_glmfit).
Can you tell me what kind of space the cluster summary list created by
mri_surfcluster refers to? Is it real Talairach space as TalX, TalY and TalZ
implies it? Is there a simple method to transform those coordinates to the
FSL standard space (MNI152)? That seems inevitable for me, since I use Peate
(a featquery based GUI) to perform model related time series extraction. Or
is it somehow possible to show the percentage signal change directly with
freesurfer?
Thanks in advance
Georg
