Dear AFNI experts,
I performed a group analysis and the effect of the factor A was significant in many voxels (30 peaks, using automated search algorithms).
The group analysis was performed with 3dMVM after a individual-level GLM on 40 subjects; activity was estimated using TENTzero function (10 non-zero betas, over 12 seconds).
Given many results, the regions of interest which are modulated by A express many 'types' of timelines (TENT activity).
My question is: to increase interpretability of the results, is it possible to "cluster" the timelines (TENT betas over time in all of the modulated voxels)? This would led to N (number of clusters) maps of modulation-over-time, which would be more readable (example, cluster1 has increased activity in A1 in the first part of the trial; cluster2 has increased activity in A1 in the second part of the trial and in A2 in the first part of the trial, ... ).
If it is possible, how do you suggest to do that?
I hope the question is clear.
Simone
