Hi,

I have some questions about using 3dmaskave or 3dROIstats

1) If I want to compute the average time series of epi_r1+orig over ROI1+orgi, I can use
3dmaskave -mask ROI1+orig epi_r1+orig
But If I would like to do same thing over whole ROI from the atlas (for example, MNIa_caez_ml_18+tlrc, or TTatlas+tlrc),
do I need to do it in the 'for loop' from ROI1 to ROIlast? or, is there any other way to do it?

2) When I see my statistical results on the AFNI GUI, and I checked the location of peak voxel by using 'whereami' function.
My result is already spatially normalized to MNI space. How can 'whereami' provide ROI name from different template, different atlas?
Is it automatically transformed to several space and provide ROI names?

3) As I mentioned in 2), my epi image is already spatially normalized to MNI space. How can I compute the average time series of epi from the MNI-anat space or TLRC space (for example, MNIa_caez_ml_18+tlrc, or TTatlas+tlrc template)? Do I need to transform my whole epi time series to certain space? or can I transform the template to MNI space and use this MNI-spaced template for 3dmaskave -mask?


Thanks

Jung
