BrainVISA

It is quite strange. There is no protection on the package. We are using Windows XP for BrainVISA compilation, packaging and testing so the system itself should not be a problem. Could it be a problem with your unpacking program ? You can try to uncompress the package on another machine (even on ano...

Hi, I suppose that a module or library from your 64 bit system is imported from the 32 bits Python provided with BrainVISA pack. This module must involve a link to libpangocairo-1.0.so.0. It seems that pangocairo is related to the GTK graphical library that we do not use because we use Qt. With the ...

The new Blender release (still in beta, see http://blender.org ) is able to manage voxel textures. I did not resist to play a bit with it. The result is not impressive as compared to what we can do with Anatomist in real time. But it could be helpful in some cases to have real transparency, shadows,...

Cool ! That's very good to display activations in 3D with sulci when a mesh of the cortex cannot easily be obtained. You ony need an image of the brain and an activation map. But to make it user friendly, we should think of a new way to play with transparency. For instance, it is quite hard to set a...

Cool. I tried volume rendering on a 2D fusion but the immediate result was strange (maybe bad transparency parameters or a 3D card problem) so I decided to ask this question before investigating further. In RGB mode, is there a way to play with transparency (I suppose that black is transparent).

I briefly tried to superimpose two volume rendering objects (one T1 MR with only the brain and one thresholded activation map) but I could only see one. Did I missed something in transparency configuration or is it impossible ? Ideally I'd like to be able to truly fusion the two volume rendering obj...

If you use a minus as th bundle name, the matching fascicles are ignored. This information is located (hidden ?) in the small paragraph about bundle names in the documentation.

The error 'Error -3 while decompressing: invalid distance too far back' is due to some compressed files that can be read on Linux but not on windows. You can get rid of it by downloading the attached zip files and putting its content in the directory cartopack-Windows-XP-...\share\connectomist-3.2\o...

For uuid generation, you can use "uuidgen" on Linux (I do not know if it is always installed). To create a new referential on a non existing minf file, you can use the following Python code (you can put it in a command-like executable Python script): from soma.minf.api import writeMinf fro...

Thank you for posting your code François.

You must have as many lines in your text file as the fourth dimension in your image. So, if your image has a dimension x, y, z, 60 importation should work. If you cannot make it, I can try it myself to see what is going on. I would need the image file(s) and the orientation/b-values text file. It wo...

During importation, BrainVISA need one b-value and one gradient orientation for each 3D volume (both can be null) contained in input image(s). There is a generic importation process takes this information on a simple text file and the correspondind images in one or more image files. Other importatio...

You can synchronise 3D Anatomist windows point of view (including zoom) by pressing the 's' key (don't forget to put all windows in 3D mode). You can set the same size to all window by using menu Window->resize (you will have to do this on each window). All of this can be easily scripted. Depending ...

There is a format problem with your images, they cannot be read by the program that is used to import them (comistConcatenation). This program can only read images where voxels are coded in signed 16 bits integers (S16). You may have to convert them. First check that your image can be read by Anatom...

Uuhh ?! Googleling this error message relevealed that it is connected to an uncompression error (from zlib). There is no explicit compression/decompression in QBall model so I bet the problem is elsewhere ; for instance in a invalid compressed file. Could you send a copy of the advanced information ...
