dear freesurfer group, is there anywhere some cookbook-like instruction for processing monkey (macaque) brain MRI data with FreeSurfer ? are there any normalized macaque brain templates needed for FreeSurfer ? thanks, bye, pisti - [EMAIL PROTECTED] ___

[Freesurfer] Segmentation optimization

2006-06-06 Thread Joao Pereira
Hello again, I've been having some problems with FS segmentation, especially around the temporal lobes, where there is a clear underestimation of the pial surface (and manual edits are not being too successful). The problem is clearly related to the poor resolution of the used images. Are there a

there are plenty of people around doing cortical analysis of monkey data, but the subcortical atlas only exists for humans. cheers, Bruce On Tue, 6 Jun 2006, Istvan Akos Morocz wrote: dear freesurfer group, is there anywhere some cookbook-like instruction for processing monkey (macaque) br

[Freesurfer] Question regarding Outputs

Hello all, The output of mris_anatomical_stats has a measurement called TotalWhiteMatterVolume for each hemisphere. From aseg.stat the measures for cerebellum-white volume and cerebral-white volume for each hemisphere can be obtain, but the sum of both the measures obtained from aseg is le

Hi Dhruman, the total white matter volume should probably be removed. It's currently the total volume of all "on" voxels in the wm.mgz volume, which won't include cerebellum. I think the aseg values should be more accurate. cheers, Bruce On Tue, 6 Jun 2006, Goradia, Dhruman D wrote: Hel

Hello, I have whole brain T1 maps and the pseudo T1-weighted images that I created out of them (so they are perfectly aligned). The are all brain extracted using fsl and I am doing my own tissue segmentation (again, using fsl), but in both steps there is much optimization involved, because I wan

have you tried just putting your original T1 weighted image through the recon stream? You can then sample your T1 maps onto the surface (which we have done in the past). You could plug into our stream after the segmentation, but you would to mirror our directory/file structure, which is going t
