Hello, It seems a Qt library is missing in the 4.3 package. Indeed, we use QtWebKit only since the 4.3 version, so maybe we forgot to put in the package a dependency of this library (QtDBus ?). Maybe you could install Qt4 (4.6.2) on your system to workaround the problem or wait for a next package......

Hello,

Hi, I have just tried the Morphologist pipeline and the head mesh is computed and readable. Did you use the latest release 4.3 of Brainvisa package ? Did you see an error message during the execution of the head mesh step ? The head mesh is in gifti format by default if the input image is in nifti f...

Hello,

Doing the online tutorial step by step using the demo data should help learning how to use Brainvisa.
But there are no training courses planned for the moment, sorry.

You will find useful examples in Aims tutorial here : http://brainvisa.info/doc/aimsdata-4.2/aims_training/en/html/ch10.html#N1083B And you are right about the coo...

Hello, If you want to run several processes via a script, it is better to use the command brainvisa -b -e myscript.py , with the code to run Brainvisa processes in a python script (myscript.py in the example). In this script, you can use brainvisa python API to run processes. Here is an example of s...

Hi, 3.0 version is quite old, I'm afraid we do not have such documentation for this version. But if you want to convert a 3.0 database to a 3.1 database, a Brainvisa process can do it for you : Data management -> Convert old database. Here are a few rules of conversion between the old and the new da...

You will find details about the organization of brainvisa database directory after version 3.1 at...

Hi,

The message you mentioned generally means that the option allow_flip_initial_MRI should be set to true to allow Brainvisa applying a transformation to the...

But it does not always mean that the results are correct or good enough to get the next steps successful. You should check the results of the previous steps anyway by clicking on th...
