Re: [Freesurfer] convert labels to volume in MNI?

2018-03-30 Thread gj
On the vcAtlas website, it says "The cytoarchitectonic atlas is available on the FreeSurfer average surface (fsaverage). Thus your data need to be aligned to the fsaverage brain." so I assumed the input label is in fsaverage space. Only labels and annot files are available from the vcAtlas -- so I

Hi all, Sorry in advance, this is a bit of an annoying one! I am trying to use freesurfer's automatically generated MT label as a parcel to constrain activity measured during a functional MT localizer. I am currently doing my analysis in the volume and I'd like to transform the MT surface label

Hi Doug, Sure. I have attached an excel sheet. I have averaged the signal magnitude across 16 blocks of objects, and 16 blocks of scenes, separately. Each block has 8 TRs (TR=2). The top plot is the data with the default -TR/2 delay. The bottom plot is the data with -2TR delay. In both plots, we

It looks like brainmask.mgz might have been corrupted. Can you run mri_info on it? Does its size look about right? Can you create brainmask.mgz again? On 3/29/18 4:06 PM, Anna Daniels wrote: Dear FreeSurfer team, after editing the brainmask.mgz (manually or with gcut), brain.finalsurfs.mane
