Re: Harmonic parameterization of the cortical surface

Hello, I should have looked at this post before I answered your next one... Indeed the 'pipeline 2012' version of the cortical parameterization process is the implementation of the paper you mention (the harmonic parameterization). It also includes the sulcal line extraction method published here: h...

Re: Cingular pole template available?

Hi, the cingular pole template is avilable in : <brainvisa>/share/brainvisa-share-4.x/hemitemplate/Template_icbmPole<Left/Right>.ima The insular pole is segmented using the insula sulci that are detected during the sulci graph labelling. I assume you are refering to the cortical parameterization pro...

OK. For only one brain, you could almost do the whole parcellation directly with SurfPaint...

Re: cortical surface parameterization : no gyral parcels

Hello François. The 2012 pipeline is not ready yet, no point using it. We're almost there, though. The old one.... I thought it worked, it has been used many times now. So I don't know what would make it not work anymore... I will check it out, but most our energy is dedicated to setting up the new ...

Re: Missing scroll when displaying an inflated brain

Hello,
I reckon that you did not save the sequence during the inflation process. That is what the slider is for: looking at the different steps of the inflation from the original to the most inflated, and I think you probably have only the most inflated surface.

extracting a subpart of a mesh

Hello,
I thought there was an Aims command to extract a subpart of a mesh using a ROI defined in a texture, but I can't put my hand on it. Before I implement it myself, could somebody confirm that it actually exist ? (if not as a command line, at least as a class ?)

Thanks,

Olivier

Re: AimsInflate doesn't save sequence [solved]

Alex, if you want to use the python API, here is a little starter. First you have to use the python that comes with brainvisa (not the one already on your system). If you want a python shell you can use the ipython that comes with brainvisa as well. Then the following code should help you to load an...

Re: AimsInflate doesn't save sequence [solved]

Hi, it might be possible with a command line but nothing straightforward comes to my mind... You can do a little python programming to do this, but probably you should chose what time step you're interested in, using anatomist, and then re-run the AimsInflate without the -S option and with a -t valu...

Re: AimsInflate doesn't save sequence

Hello,
I think that the file contains the whole sequence. If you open it n a 3D window with anatomist there should be a slider on the side that allows you to see all meshes in the sequence.

when one clicks somwhere in a volume slice, the coordinates (voxels and mm) are displayed in the command window. These are image coordinates. I was wondering if it is possible to get the coordinate in one of the referentiels attached to the volume...

Re: Redraw problems on OSX 10.6

Hello there, I actually have the same problem although I compiled everything on my own 10.6 machine. It has not been a big enough problem for me to care too much about it, I had too much to do otherwise. I suspect it is a problem related to the focus of the mouse on 10.6 but I am not sure about it. ...

New recognition session for manually labeled graph

Hello, I would like to know what is the best way to manually label a sulcus graph. More precisely, I want to change labels using anatomist color 'copy and paste' tool, and I want to save the graph under another 'sulci recognition session' (a manual one) that will be accessible in BV's database. Is t...
