[Freesurfer] Very strange error in surface reconstruction after a2-cp

Dear FS experts, I have a very strange error after running autorecon2-cp. I never saw this kind of error with previous versions of FS. I run recon-all -all on my subject, and obtained very good surface reconstructions, with the exception of few excluded wm voxels (see attachment called "befo

[Freesurfer] Can -autorecon2-cp and -autorecon2-wm be run at the same time

Dear FreeSurfer experts, I am quite new to FreeSurfer and I am trying to analyze some patients. We run -autorecon2 step and we got some errors both in the intensitiy normalization and in the wm segmentation, so what we need to do now is both to add control points to the brainmask.mgz image and to

[Freesurfer] adding control points

Dear FS experts, we have run autorecon2 on a set of subjects and now we are in the process of manual editing adding control points. We read the tutorial about the manual editing; however, sometimes we have some doubts about adding or not adding control points in some regions. We had a look at t

[Freesurfer] Questions about Qdec

Dear FS list, I have a couple of questions about QDEC toolbox. 1) If I perform a multiple regression model and I obtain a significant cluster of correlation, is it possible to extract the corresponding regression coefficient, in order to report the strength of this correlation at that point?
