The entries for Hippocampal volume in ADNI-MERGE.csv seem very large. (They do NOT agree with the sum of Left+Right from UCSSNTVOL.csv) Can you clarify this?
Thanks.
The entries for Hippocampal volume in ADNIMERGE.csv are taken from the UCSF FreeSurfer files (sum of left and right) not from UCSFSNTVOL.csv. The units of measurement are mm^3.
