Re: [Freesurfer] recon-all: making sure that brain.mgz will be in RAS orientation.

Hi Noam if you want your outputs in a specific coordinate system, why not just run recon-all, then mri_conver to whatever orientation you want? Internally we have a consistent orientation that you can't easily change cheers Bruce On Sat, 9 Mar 2019, Peled, Noam wrote: Dear group, I ran

[Freesurfer] recon-all: making sure that brain.mgz will be in RAS orientation.

2019-03-08 Thread Peled, Noam
Dear group, I ran recon-all on a T1 nii file, which is in LAS orientation. The brain.mgz turn out to be in LIA orientation. I've tried to convert the nii file to RAS (mri_convert --in_orientation LAS --out_orientation RAS ...), and rerun recon-all, but it didn't change the results. How do I

When you have such a low threshold, the resulting p-values are very liberal. See our paper https://www.ncbi.nlm.nih.gov/pubmed/29288131 Should be fine for exploratory On 3/7/19 7:48 PM, Arsenije Subotic wrote: > External Email - Use Caution > > Hello, > > I am planning on running a

Yea, the real hard part is figuring out how to model the twins that are split between groups. You might be able to create a bunch of groups. If you've already created a design in FSL that you like, you can extract the design matrix and use it in mri_glmfit with the --X option. Not sure about
