if you want to mask the thickness, then use mri_mask On 10/10/2018 10:30 AM, N Saf wrote: > > External Email - Use Caution > > Dear Douglos, > > as you recommended, I used the --outmask and create the binary mask of > a label in mgh format. as I use the mri_binarize command with this >

External Email - Use Caution Dear Douglos, as you recommended, I used the --outmask and create the binary mask of a label in mgh format. as I use the mri_binarize command with this mask and ?h.thickness; the output is binary too or if I use --match flag or --min --max flag the

External Email - Use Caution Dear Douglos, I did not understand how to use mri_label2label with the mask option(there is srcmask options not mask alone !). I extract my labels and as you explained I wanted to create i.e. binary mask of rh.fusiform.label with mri_label2label :

Yes, that should work. You can create a mask by breaking the annotation into labels (mri_annotation2label), then converting the label into a binary mask (mri_label2label with --mask option), then mri_binarize --i lh.thickness --mask youmask.mgh --o lh.thickness.masked.mgh On 07/30/2018 01:47

I think you could just load the cortex.label map onto the surface and edit those regions out. Then they will not contribute to smoothed maps, etc... Doug: any reason this wouldn't work? Bruce On Tue, 13 Feb 2018, James Hobart wrote: > Hi all, > I am looking to mask out a small region of the

[Freesurfer] Masking cortical thickness

2018-02-13 Thread James Hobart
Hi all, I am looking to mask out a small region of the GM when calculating the cortical thickness of ROIs across the brain. Essentially I have a couple of cases with small GM lesions where the cortical thickness is less likely to be meaningful for my analysis. I have binary lesion masks and also
