[Freesurfer] wm.mgz edits get overwritten surfs not correctly re-generated

Hi everyone and happy new year! I made a couple of manual edits to a wm.mgz file and then relaunched part of that subject's recon (-autorecon2-wm -autorecon3). After it finished, however, the wm.mgz had lost its manual edits - even though I had saved the edited version under the same name, in the

Hi Yuliya they are included if they are inside of the ?h.pial surface. We don't use the cortex aseg label as it is in general less accurate than the surfaces. cheers Bruce On Sun, 5 Jan 2014, Yuliya Yoncheva wrote: Dear FreeSurfer community, I am visually inspecting the quality of my recon

Hi Octavian it's not so easy to reduce the bandwidth in the T2-space sequences, but certainly you can try. Geometry-matched just means that the FOV and matrix sizes are the same. cheers Bruce On Fri, 3 Jan 2014, Octavian Lie wrote: Dear Bruce, Best wishes for 2014! I will heed your

Hi Katica what format was the input image to recon-all? Can you verify that tkmedit has the directions correct (that is what it labels as anterior is actually anatomically anterior, etc...). If so, then the talairach just failed and you will need to either try an alternative (like the MNI or

[Freesurfer] ROI masks created in FreeSurfer used in FSL??

2014-01-05 Thread Frank Hsieh
Dear FreeSurfer Users, I ran recon -all on my structural image and created ROI masks (using mri_label2vol) based on FreeSurfer's cortical parcellation. I'd like to use these masks for further analysis with FSL. However, it seems that the ROI masks generated with mri_label2vol have different
