Dear BOb,
I have large data set of FA maps for subjects of different age converted into standard tlrc frame. I would like to test if the values for a given voxel follow a linear or other type trend with age. I am not sure which afni program should be used to do this kind of modeling test? I tried 3dDeconvolve, but it is tricky to convert the age data as a stimuli. I would appreciate very much, if you give me some tips on this. Thanks, -Tie
