medial wall crossing surface
by celine＠nmr.mgh.harvard.edu 18 Jun '13

18 Jun '13

Hi Freesurfer team I am wondering if there would be a way to improve surfaces on the medial wall, not for the measurement of cortical thickness, but also for laminar analysis in the cortex. We would need them to be accurate even for the medial wall. What would you suggest? Thanks Celine -- Celine Louapre, MD Research Fellow at Massachusetts General Hospital Department of Radiology, MGH Building 149, Room 2301 13th Street Charlestown, MA 02129

Temporal Lobe Problem
by LIOR ZWANZIGER 18 Jun '13

18 Jun '13

Hi, I have scans of around 60 participants and about 75% percent of these have significant portions of their temporal lobe excluded. I have attached different slices from four different subjects to give you an idea of the typical scan I've been encountering, [though there are problems in minimally 10 slices for each participant and some exclusions can be found in more than 50 slices.] We are using FreeSurfer version 5.1.0. What is your advice, since there are so many slices for a large number of participants that would need to be edited? Extension of the watershed parameters, adding control points, or something else I haven't considered? I am hesitant to add control points for such a great number of participants. Thank you! Lior Zwanziger

Group Analysis
by Nooshin Zadeh 18 Jun '13

18 Jun '13

Dear Freesurfer group I am interested to do group analysis on my data. If I want to do inter-individual group analysis, what is the minimum number of subjects I need to have? Also if I want to do intra-individual analysis, what is the best way in FS? I appreciate your time and your help. Thanks a lot, Nooshin

Hi Freesurfers, I am trying to use Freesurfer to convert DICOM files to nii f.nii files. Freesurfer is able to find all the DICOM files but always gives me an error: "ERROR: reading DICOM/59175096 tag 28 30". Can anyone help? Thanks, Luc -- Luc Amdahl Brown University '14 Sc.B.
