How to extract time series data for multiple ROIs using an AAL mask

AFNI Message Board

Hi,

An AFNI newbie here.
I would like to extract time series data from my fmri file for each ROI, as defined by an AAL mask (AAL3v1.nii). Would there be a one line command that can do this?

Right now my command looks like this:

3d 3dROIstats -mask AAL3v1.nii my_fmri_file > timeseries_AAL

This command generated an output with the right number of columns and rows, but I wanted to double check that this is doing what I am looking to do.

Thank you so much!

AFNI version info (afni -ver):
24.0.12


3dROIstats -mask AAL3v1.nii my_fmri_file > timeseries_AAL

Sure, that 3dROIstats command looks reasonable.

If you use the AAL version here, then it will come with labels on top too.
AAL3_dist.tgz
