BrainVISA

Thank you very much for the answer. In fact, I already wrote a (small) document to describe how to do that kind of thing (in fact, only what I found out), and as soon as I consider it ok, I will send it to you (and translate it in english if I have time for this). I understand much better the use of...

Hi all, I am trying to create a specific database hierarchy. I know how my data should be organized, and I try to write a BrainVisa hierarchy to meet my needs. Is there a tutorial somewhere about writing a hierarchy ? I am using shfjHierarchy.py as a template, and I declared the new types I needed i...

Hi, I need to store data unrelated to subjects, and I wonder if it is ok to put it in the BrainVisa database by changing its hierarchy. I need to store electrode meshes (or electrode graphs with the associated named hierarchy, for the colors), and have those meshes available in a BrainVisa script. I...

Ok, thanks a lot for the explanation. I just tried to link the parameters, and everything works perfectly now.

Ok, thanks, I understand much better now. I just have to link the parameters. I suppose it is more coherent to always use the same referential by default to transmit coordinates from Anatomist to BrainVisa (the red one), but I thought Anatomist transmitted the coordinates in the referential of the w...

Ok, thanks, but I don't understand why it still doesn't work correctly with the latest (perforce) version, if the bug is corrected. I got the same problem with 2.3 package and perforce version (maybe not the same values, I didn't check). I can try to use the Talairach referential, but for now, when ...

Hi, I am trying to get the coordinates of two points selected with a mouse click (in Anatomist) in BrainVisa. This is probably a silly mistake, but I do not understand the results that I get : - I made a BrainVisa script with the following signature : signature = Signature( 'T1mri', ReadDiskItem( &q...

Yes I did have this problem, but that is just because I had not given a valid hierarchy for the database. I added the path to the shfjHierarchy.py file of the brainvisa directory, and now it works. If you did provide a valid hierarchy file, could you describe more precisely what you did to add the d...

Hello, the python directory (and include file Python.h) you are looking for is not supposed to be in BrainVisa : it is supposed to be installed on your computer. You should have Python installed on your system (with the development package) to use BrainVisa. On my computer here, python include files...

Hello all, I would like to know if it is possible to create a graph hierarchy (.hie) with multiple names or labels, as those names would be equivalent (latin, french, english...), and then select the language to display in Anatomist. I can create multiple .hie files, one for each language, and let t...

Ok, thanks a lot for the information. I still don't understand everything about graphs, but I was able to create a hierarchy and make a program which imports my data (as a xml file) and generates a graph corresponding to the hierarchy. One last question : is it possible to store the transparency in ...

As I am writing a C++ program, the code you gave is really useful to me. But I just have one problem right now, concerning the insertion of meshes in graphs. The following line : GraphManip::storeAims( *g, v, "aims_Tmtktri", meshes[i] ); does not compile. I noticed that this function is a ...

Ok, I think I will try to use the graphs. By the way, is there a documentation about the creation of a .hie and associated .arg files ? If not, I will first try to understand the nuclei example. About the .minf file, I just wanted to use it for my tests on one subject, so the entropy wouldn't have i...

I see there is some documentation about hierarchies and arg files (http://brainvisa.info/doc/html/anatomis ... graph.html), so I will try to understand how I can use it.
Thank you for the answer !

Hello all, is there a simple way (without textures or brainvisa scripts) to store the color and transparency properties of a mesh for Anatomist ? Right now, I generate about 12 meshes, and each time I open them in Anatomist, I have to change the color of each one manually. I thought maybe that kind ...
