Re: Bug in diffusion to extended AC/PC referential ?

Hi, this module does not seem to work yet... When I try it again I get this error message (it seems as if AC/PC was calculated correctly but then EACPC does not): Traitement Diffusion to Extended AC/PC referential 1 démarré sur 2010/06/15 17:05 xMin, xMax : -47.8147372 , 221.44459 yMin, yMax : -33.9...

Re: Error message in Tracking pipeline

Hi Sandra,

I got the same issue and found the solution: you have to fulfill the "density_map" and put a name for the file being created (even if indicated as not mandatory, I think this is an error)

Re: volume calculation

Hi, Thanks for the AimsVoiStat command explanation. Its output is like this: RoiName| StTime| DuTime| Volume| Mean| StdDev| Min| Max I tried this on a single arg drawn on a T1 image; therefore I don't understand how it outputs a Mean, StdDev, Min and Max ? What are StTime and DuTime for ??? thanks, ...

Re: Error message in Tracking pipeline

Hi Sandra,
In which submodule of the pipeline does this error occur (tracking ? bundles transformation ? bundles analysis ?) ?
Have you attempted to execute each of these modules separately ?
Best,
Josselin

System recommended for Brainvisa ?

Hi, I know a post was made a few years ago about this topic (http://brainvisa.info/forum/viewtopic.php?f=2&t=447) but I would like to get an update on it. I am going to buy a PC, mostly to process DTI data with brainvisa. More precisely: -do you think the windows version is as reliable as the li...

Re: Bug in 3.1 "Brain Mask for T2" in diffusion pipeline

Hi,
No, I took a new raw image and created a database from it.

Please note, that by undergoing exactly the same steps, I get this bug only in the 3.1 Linux version and not in the 3.1 Windows one...

Bug in ROI drawing with anatomist 3.1

Hello, I found another bug in anatomist 3.1 which doesn't exist in 3.0.1, while drawing: it works nicely when you are drawing with the ROI tool box a first ROI. But when you add a second ROI and you try to draw it, it is impossible: clicking on voxels does nothing, doesn't draw the ROI. So I have to...

Re: Ignoring/averaging several T2images in diffusion importation

ok, thanks
in the "generic diffusion importation" process, under which format must I inform the fields "bvalue" and orientation ?
and how must I put the images ? one file by one file or in a 4D volume ?
thanks

I have checked the RGB maps and they look pretty similar overall especially for the corpus callosum or pons regions. Do you think it is ok ?

I can't find the "Generic Diffusion Importation" process (I put the User level to expert).
Is it only available at Neurospin ? Is there an AIMS command for it (in the brainvisadev pack) ?
