Hello,
Is there a way to get an automatic segmentation of a T1-image with Anatomist ? I mean, a segmentatin of the brain into Brodmann Areas which would define different Brodmann areas as differents ROI ?
Thanks

question about the interpolation update in 3.0.1
Hi, In the changelog about 3.0.1 version of Brainvisa, you wrote "An error was fixed in linear interpolation of Aims library. This interpolation is used in several algorithms including diffusion and fiber tracking. " So are diffusion results (I mean results get from diffusion tensor and di...

how to resample a bundle ?
Hi, I would like to resample a .bundle file (to apply a T2=>T1 transformation from a .trm matrix I have and resample it to the T1 image). Is it possible ? What's the command ? Does it need to be resampled to the T1 image or applying the transformation with "Diffusion Bundles Transformation"...

What does "Resample ROI graph" really do ?
What does this component do when we only put as input the original ROI graph and the "destination" image ? (I mean, without any transformation matrix). I ask this question because this component give to me the best result I can have to draw a ROI in T2 AC/PC image from a T1 AC/PC image. Th...

Has thresholding T2 an impact on diffusion analysis process?
Hello, Thanks everyone for you previous answers. Sometimes when I use the "Diffusion to AC/PC referential" on my diffusion and T2 images, I have got a acpc_T2 image with a texture_min at -32768 (usually it is near zero). The problem is that this kind of image is quite "blank" or ...

how to create ROI in AC/PC T1 and T2 ?
Hello, I am using Brainvisa 3.0 for fiber tracking. I register all my images (T1, T2 and diffusion) in AC/PC referential. To create my T2 and diffusion in AC/PC I use the component named "diffusion to AC/PC referential". To create my T1 in AC/PC I use the component "Apply Transformati...

What do the"bundles features" statistics describe
What do the statistics "Volume Ratio Image" (vr) , "Standard Deviation Image" (stdev) and "Diffusion-weighted T2 image" (dwt2) in the bundles-features statistics mean ?
Thanks
Thanks
