Dear SPM team,
I am using VBM and would like to correlate GM/WM volumes in certain brain areas with gene expression in those areas using transcriptomic atlases.
I have obtained the average expression for some genes but I am unsure about how to proceed now.
Should I obtain the average T value for a certain ROI?
Is there a way of obtaining the average volume change for each region (i.e. caudate, cerebellum...) using get_totals or spm_get_volumes so I could perform standard statistical correlations with gene expression in those areas?
Many thanks,
Carlos
