Problems with Tracking Fiber

[achilleteillac]

Hi,

I'm a new user of BrainVISA (4.1.0 on Windows XP) so I followed the tutorial about Diffusion and Tracking in order to see the .features file create by the diffusion bundles analysis step.
After I passed the Fiber Tracking step, I can't generate the .features file because apparently of the bundles file format.
I get these errors :

"comistBundleAnalysis: Bundles required in format bundles_1.0


in Diffusion Bundles Analysis 1 System command exited with non null value : 1

Thanks for any help or leads you can give me.

Hi,

Thanks for adding the error message, but we need of the brainvisa.log file to understand why the process has failed.
To save this file, please take a look at:
http://brainvisa.info/doc/axon-4.1/bv_t ... tml#N100CC
If the last time you used BrainVISA, the error has happened, if not necessary to launch again BrainVISA to run the process.
But, if you have used BrainVISA for anything else, you have to run again the brainvisa process to report the error message in the brainvisa.log file.

In order to send me the file, I think you know who I am, so I think you have my private email. Otherwise send me a private message by the interface of the forum.

I would like to check one thing: have you visualized the .bundles file by clicking on eye ? because if this file don't exist or if it's empty so the "Diffusion Bundle Analysis" process won't work.
