[Freesurfer] convert size

Hello FS experts, I would like to to convert binary images from size 256,256,256 voxels to size 256, 256, 256. Is there any FreeSurfer's module to make it? Thank you very much Andrea ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu

[Freesurfer] Parcellation of cerebellum.

Dear freesurfer, I'm trying to perform parcellation on the cerebellum. After reading closely freesurfer wiki and the questions related to this topic on the mailing list, my understanding is that there is no way to perform fully automted cerebellar parcellation on structural mri with freesurfer.

Hi Charles that is true at the moment, although we are working on something that should be ready relatively soon. cheers Bruce On Mon, 10 Dec 2012, charles laidi wrote: Dear freesurfer,  I'm trying to perform parcellation on the cerebellum. After reading closely freesurfer wiki and the

Re: [Freesurfer] convert size

Hi Andrea I think there is a typo in your email as your sizes are the same. If you have a volume you would like to reslice it like you can use the -rl volume option to do what you want. cheers Bruce On Mon, 10 Dec 2012, Andrea Tateo wrote:   Hello FS experts, I would like to to convert

Re: [Freesurfer] winkler surf data with qdec ?

Greg, one of the -qcache outputs is named 'fwhm0', which will be unsmoothed. you can also specify creation of just that file by adding '-fwhm 0' after the -qcache flag. Nick Hi , I have winkler variety surface area data that is already smoothed and converted to vertex wise data on my

Soory if I bother you again, actually I would like to convert from 256,128,256 to 256,256,256 and from 181,145,181 to 256,256,256. Can you tell me the complete command and not just the option. thanks immensely Andrea Messaggio originale Da: fis...@nmr.mgh.harvard.edu Data:

[Freesurfer] motion correction

Hello, Our data set has two T1 weighted scans for some subjects but only one for others. Would you recommend running all subjects with no motion correction (1 scan input)? Also can files be mixed in the analysis that have had motion correction with those who have not? Thanks! -Andrew

Hi Summer, there is some documentation in mkanalysis-sess -help. It's not very much documentation, so I just wrote a little bit more which I have included below. Let me know if you still have questions. doug -abblocked PeriodSec Design is AB-Blocked (ie, periodic, two condition). Specify the

[Freesurfer] which step comes first

Hi, when reconstructing the brains including manual edits, does the step that incorporates control points come before the white matter edits? Ie so if I do both control points and white matter edits, will the white matter edits be take into account even if I just use -autorecon -cp , and not -wm?

Re: [Freesurfer] nuisance variable ICV

Hi Stan, I don't think you have to correct thickness for head size or grey matter volume, but you should do so for subcortical volumes. Whether you use ICV or GM volume or brain volume depends on what you believe is happening and what hypotheses you want to test. Check out the paper by Randy

Re: [Freesurfer] which step comes first

Hi Catherine, Using the -autorecon-cp will take care of both cp and wm edits. Be sure to run -autorecon3 afterwards if you are satisfied with the edits you made. -Louis On Mon, 10 Dec 2012, Catherine Bois wrote: Hi, when reconstructing the brains including manual edits, does the step that

Re: [Freesurfer] nuisance variable ICV

In addition to the Buckner article, for other literature on the topic of adjusting for volumes you can see: O'Brien et al., Psychiatry Research: Neuroimaging 193:113-122 (2011) Sanfilipo et al., Neuroimage 22:1732-1743 (2004) I'll also mention that people sometimes use global global thickness as

Hi Shige, those are fine, but there is a warning here about performing the mri_surf2surf step. You need to make sure that you are doing this properly because it will run and complete even if you are not doing it properly:). to map the left hemi, run something like: mri_surf2surf --srcsubject
