Please also consider that the T1, f.nii and ROI.ii.gz (obtained by label2vol) are nice overlapped. The brain.mni305.2mm.nii seem to be strange (see the image attached). In the sig.nii.gz the cluster are bad coregistered and some of those out are of the brain.

abnormal inflated surface
by Jasmin Alves 12 Feb '16

12 Feb '16

Hello freesurfer, I received this odd inflated surface image. I am not sure if this is something that can be fixed via a registration step or should be fixed in another step. Your input as to how to correct this image would be greatly appreciated. Also, I noticed that this participant's hippocampal volume is half the amount compared to the rest of my participants. Is it possible these two problems are related or am I possibly dealing with two separate issues? I have attached a screen shot of both problems. Thank you very much, Jasmin -- Jasmin Alves Predoctoral Student Medical Biology Graduate Program University of Southern California jalves(a)usc.edu

Freeview to mark only one specific area
by Luis Fernado Silva Castro de Araújo 12 Feb '16

12 Feb '16

Hello Freesurfer experts, I want either a 2D or 3D picture of one of my subjects image, but with only one colored area. For example, I would like to mark the lh_lateralorbitofrontal_area. It seems that the tool to visualize images in Freesurfer is freeview, however I can't find the label for the left hemisphere lateralorbitofrontal_area in the GUI. It is not listed in the Volumes tab with the aparc+aseg item ticked. I did not find information in your website, maybe I missed. Could you please provide a pointer towards the answer? Maybe I missed where it is taught at the documentation, a simple link would do. Thanks, luis

FreeSurfer MRI segmentation
by Maheen Siddiqui 11 Feb '16

11 Feb '16

Dear FreeSurfer Users, I have a T1 weighted MRI scan and have run the recon-all command on it. For my steps moving forward I need to have 4 layers of tissue i.e. 4 segmentation files - GM, WM, CSF and extra cerebral tissue. Which of the outputs from recon-all will give me the segmentation? I thought at first that brain.mgz was what I needed but having viewed brain.mgz in Freeview, it is just the skull stripped version of the T1 scan. Is there any document that details all the outputs of recon-all? Many thanks for any advice I can get! Maheen
