Hi,
I extracted thalamic, caudate, and putamen volume (left hemisphere), and cingulate thickness (right hemisphere) from freesurfer's parcellation. Then I compare these volumes and thickness across two groups using R and found significant differences in these measurements. Do I have to correct for multiple comparisons?
If yes, how do I do that? Does this make sense to divide the p-value/4 and if the p-value < p-value/4 then the test is Bonferroni corrected? If no, what do I say in my results that the test statistic is not inflated?
Thanks
Regards
