I apologize if this has been asked and answered before, but I wish to combine rostral and caudal middle frontal gyri for a summary measure. To find the average thickness of the entire region, will it be weighted by the surface area or by the number of vertices?
Avg_MidFront = ((CaudThick*NumVertsCaud) + (RostThick*NumVertsRost) / (NumVertsCaud + NumVertsRost)) Or Avg_MidFront = ((CaudThick*SurfAreaCaud) + (RostThick*SurfAreaRost) / (SurfAreaCaud + SurfAreaRost)) Thanks, Ronald Pierson Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
