I tried several times and I always had the same problem.
The development version is 20 days-old, and my image is a S16 GIS file.
I'll try again with a more recent version.

To do this, you can check if the text filetype is defined in BrainVisa : - in the file "SHFJ-pack****/brainvisa/types/builtin.py", format of files and filetypes are defined. - to add a new format, you can write in a file ("newTypes.py", for example) : Format( 'Text File', ['f|*.t...

Small bug in Point3D()

Hi all, I just used a modified version of the BV process to register ACPC coordinates on a T2 mri, and I used the Anatomist icon to get the AC coordinates. While doing this, I changed the MRI palette settings (min/max inverted to see something more like a T1 mri) in Anatomist, and when I clicked on ...

As stated in the error message, you have probably forgotten to fill the "dip_mesh" line when running your process in Brainvisa :
you should enter the path to the file that will be written, using the "folder" icon at the right of the "dip_mesh" line.

Could you please give the error message or describe your problem ? I see two problems here : there is no indentation (but I assume there is in your actual process), and you wrote "def execution(delf,context): " instead of "def execution(self,context): ". If you want to see the ob...

Thanks a lot !

The results I get with

Code: Select all

VipSkeleton -i frame.ima -v n -c n -sk s 
look like the image I expected.
I still have to check that my other programs work correctly with the computed skeleton.

Hi Michel, for this, you need to compute the transformation from the T2 referential to the T1 referential, with a registration program. There are some of these programs in "registration" processes in BrainVisa ("recalage" in french), but I don't know if they work with two differe...

Ok, but I suppose the problem is easier in my specific case, because I just want to get the skeleton of a stereotactic frame (two rectangles, one for each side of the head), not a complex object.
Thank you for your help.

Thinning

Hi, I would like to know if there is a command (or a function in Aims librairies) for the "thinning" of a 3D shape : - I have a 3D GIS image that contains an object extracted from an MRI. - I have a template of this object which is 1-voxel wide - I want to get the thin version (1-voxel wid...

If it is a T1 MRI image, I would have imported the image using BrainVisa "data management / Importation / anatomy / Import T1 MRI" : you can choose any slice of your image as input, and the whole 3D image will be imported as a GIS file into the BrainVisa database. If you prefer to use the ...

Ok, I had forgotten the fact that selecting the root node selects also all the subnodes...

I guess I must dive deeply in the anatomist libraries to add a new functionnality like what you proposed.
Maybe after a course on Anatomist structure and libraries, I would be able to do so !

SelectByHierarchy

Hi, I need to display a graph composed of a few meshes, according to a hierarchy describing the colors I would like to use for each node of the graph. This is done through a BrainVisa process using Anatomist.py How can I selectByHierarchy all nodes which names are described in the hierarchy, without...

context.system(....)

Hi all, I have a slight problem with context.system(...) I wrote a process that extracts some objects from the MRI, and makes one mesh combining all extracted objects. Because AimsMesh creates one file per connected component, I wanted to use AimsZCat to create one mesh from those created by AimsMes...

In fact, I just tried to use the 'palette' key, and I should have tried the 'texture' properties, as you said.
Everything works now !
Thanks,
