Hi Nicolas, a texture generated by Anatomist (I supposed you fusioned a volume with a mesh or something like that) is rescaled between 0 and 1 (I think) because of the OpenGL mechanism used to create the texture. I don't think there is anything you can do about it, Denis can correct me if I'm wrong....

Thanks Yann,
indeed I did not have any of those encoder. I managed to do it by hand from the jpeg images using the mpeg2enc encoder, though.

Hello, I've been trying to use AnatomistViewAnimation. It works for viewing the animation and saving the jpeg images, but the encoding fails... I get the following message : ------------------------------------------------------------------------------------------------ dans Anatomist Voir Animation...

Hello,
I would like to know the specifications of the tranformation matrix files (.trm). Is there any documentation about those ? Is it just the 4x4 matrix written in an ascii file ?
thanks,

Olivier

hello, the parcellation into gyri (Surface Based Analysis -> Gyral Parcellation, user level=2) does not have "recognition" per say, but it uses the results sulci recognition. Therefore gyri have a label that identifies them. The brainvisa process generates a graph of gyri and also a textur...

Hello, I have been using the pipeline05 to process old 'not-so-good' images. I have noticed a strange thing that happens on all images with the default parameters : the brain mask looks like it has been "closed" (morphologically). That is of course propagated to further steps, and even the...

Hi,
I noticed that Anatomist is VERY slow (I mean very, it can be up to a minute on my bi-xeon machine) when asked to delete a graph (Objects->Delete object). I was wondering if it is a known bug, or something to expect because of the delete mecanism ?

Olivier

It works, thank you very much Yann.

Hi there,
is there an easy way to get the path and name of a file without the extension ? As far as I understand, file.fullPath() returns the name with the extension.
Thanks in advance,

Olivier

Hi, .arg is a format that describes graphs, .ima is a format that describes images, so I don't understand what you are trying to do. Could you be a bit more specific ? To anticipate a bit your answer, there is one thing that seems to fit with your request : all the sulci in a graph are described by ...

Hi,
there is already a topic on that subject on the forum, have a look at it :

Good luck,

OK, I found a way to do it with AimsFileConvert.
Sorry about that...

Hello, I would like a command to convert a binary volume into a .bck file. I found AimsSlice2Bucket but it does the job slice by slice, generating far too many .bck that I have to concatenate afterwards. Is there a command that does all slices into one .bck file ? If not, is there a reason for that ...

Yes, you are both right, it seems much simpler to edit the names to then extract the pieces I want. Well, it's good news because it's simpler, but bad news because I lost quite some time trying to have this module working. Anyway, I should have asked you first. That's the lesson of the day : always ...

Hi Jeff, Why not using anatomy/morphometry/Create Sulcus Label volume? well...first because I did not know about this process, there are too many Brainvisa process to know them all, now. But anyway, as far as I understand, this process gives one image label per sulcus name/label. I want the user to ...
