Problems with GM segmentation -- How to solve it
by Rosalia Dacosta Aguayo 12 Dec '18

12 Dec '18

External Email - Use Caution Dear Free Surfer team and Bruce, I have been doing well editing the skull stripping, and using control points to improve white matter segmentation. Furthermore, the few participants I had problems with due to large ventricles were solved using the flag you recommended me to use. I am very grateful for all your help. However, I am facing another problem I thought I could solve using control points as well but this is worsening things instead of improving them. I refer to grey matter segmentation. I have found that several participants, more than I would like, are having problems with grey matter segmentation in the ventral temporal lobes and in the occipital lobe as well. I wonder if you could kindly help me with this, telling me how I could solve this problem so GM and WM segmentation are fine. Yours sincerely, Rosalia

aparc regions misclassified
by Simon Jones 11 Dec '18

11 Dec '18

External Email - Use Caution Hi all, I have some participants whose recons look OK except the parcellations are incorrect. For instance the right precentral gyrus should be postcentral in three people. This appears as a shifting of multiple regions posteriorly. Is there a way to fix this? Thanks for your help, Simon

Classification of amygdala subregions using Freesurfers new Algorithm
by Sally Grace 11 Dec '18

11 Dec '18

External Email - Use Caution Dear Eugenio and experts, I have run the segmentation of the hippocampus subfields and nuclei of the amygdala using the latest algorithm implemented in the development version of Freesurfer. We have a priori hypotheses regarding the basolateral amygdala. I understand that you have broken the amygdala output down into the distinct subregions, e.g., the basal, lateral and accessory basal amygdala nuclei. Based on this reference https://www.physiology.org/doi/pdf/10.1152/physrev.00002.2003, my understanding is that the "basolateral nucleus" is comprised of the basal and lateral nucleus of the amygdala and the "basolateral nuclei" (aka. basolateral complex) comprises basal, lateral and accessory basal nuclei. So, I can create a variable called the "basolateral nucleus" (by adding together the basal + lateral) and the "basolateral complex" (by adding together basal + lateral + accessory basal). Is this assumption correct? Kind regards, Sally.

segmentHA_T2 newbie questions
by Freesurfer 11 Dec '18

11 Dec '18

External Email - Use Caution Hi, Trying to run the HippoAmig segmentation with T1-w and T2-w files for the first time and I have a few basic questions I could not resolve looking on the FS wiki: 1. Does the T2-w image need to be first recon-all processed like the T1-w? On the wiki the command line is: segmentHA_T2.sh bert FILE_ADDITIONAL_SCAN ANALYSIS_ID USE_T1 2. Does “bert” correspond to the directory for recon-all subject “bert” after been processed? 3. Does the FILE_ADDITIONAL_SCAN need to be a nit scan or should it point to the freesurfer directory post recon-all (this is kind of related to question #1 I realize). 4. In ANALYSIS_IS can I type just “T2”? Thanks! K

Freeview Scrolling through slices on a Mac
by Chris Petty 11 Dec '18

11 Dec '18

External Email - Use Caution Maybe I am missing something, but how can I scroll through slices with keyboard or mouse in Freeview on a Mac? Nothing I’ve tried works thus far. Any typical key ( cmd, ctrl, shift ) with scroll just zooms. Up/down moves the image up and down … shift / option / cmd with up / down either zooms or moves up / down. I’m just trying to add control points and definitely need to scroll through slices without clicking on the image. Thanks, -Chris

Version 6.0.0 or 6.0.1?
by Kirstie Whitaker 11 Dec '18

11 Dec '18

External Email - Use Caution Hi Freesurfer team, On the download website version 6.0.0 is linked: https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall But on this list there has been discussion of version 6.0.1 which can be downloaded from https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.1 What's the recommended version to use? I've been using 6.0.0 but with an updated make file following the instructions in this email: https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2018-April/056644.ht… Is the makefile updated in 6.0.1? Are there any other differences? I'm having a lot of difficulty getting recon-all to run reliably with 6.0.0 (some subjects are fine, others not!) and I'm wondering if that's because I'm supposed to be using 6.0.1? Thank you for your help!
