Hi Efrat,

it depends what you are doing. Usually people regress it out in a group analysis or correlation with a demographic/neuropsyc variable, but if you are reporting the true volume then you can do either (or both)

Dear FreeSurfer expert,

If I want to report on hippocampal volume in an article, should I report the value as stated in the aseg.state table or should I normalize the value to the eTICV ( i.e aseg value/eTICV )?

Thanks in advance Efrat
