BrainVISA

Hi, after running the "BrainVisa Freesurfer Pipeline" in the "Freesurfer" toolbox (which completed without errors) i have "lh.aparc.annot.tex" and "lh.r.aparc.annot.tex." files for my subjects. is it possible to make one of these .tex files fit the "*_Lhe...

Hi, thanks. then just to clarify to other people on the forum interested in 'Fold Opening': in the paper by Jouvent et al. ("Longitudinal changes of cortical morphology in CADASIL", NeuroBiology of Aging) where it is stated that: "Fold opening (Fop; distance between each gyral bank de...

Hi Prof Mangin and others, i'll try to clarify my doubts by attaching a drawing, please have a look at it. on the picture you see a rectangular prism, representing a sulcus with a middle wall, representing a median sulcal mesh. the median sulcal mesh has (amongst others) a right and left-handed surf...

Hi, in this forum it has been stated that 'Fold Opening" is defined as: "Fold opening, as we calculate it, is a more or less indirect measurement of the width of the CSF in the sulcus: it is the volume of CSF in the sulcus, divided by the surface of the skeleton mesh". my questions: w...

problem solved, my bad.

Hi, given that the linux 64 bits package was released on 2012_02_17 (not on 2012_02_16) and my README file reads jjanssen@neurojoost:/usr/local/brainvisa$ more README BRAINVISA / ANATOMIST INSTALL INSTRUCTIONS Pack Version : 4.2.1 Release date : 2012_02_17 #################### # INSTALLATION i gathe...

Hi Isabelle, >Or maybe there is another way to extract some sulci from a graph and export them to a vtk scene ? if you want to automatically extract-and-save (in .mesh format) a single or multiple sulci from the graph you can check this post: http://brainvisa.info/forum/viewtopic.php?f=2&t=1560 ...

Hi,

1st time i use it (in version 4.1.0).

no, other processes such as Morphologist work fine.

i have exactly the same (same error message) problem on Linux joost-laptop 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:39:03 UTC 2011 x86_64 GNU/Linux

Hi,

just to add to my previous question i've attached a picture. so my question remains: is it possible to correct this parcellation error within Brainvisa? i tried renaming the sulcal labels and this didn't help. is there any other way? if so, how can i do it?

merci,

Hi, i've used the "Gyral Parcellation" in BV4.1. the results look decent. however, sometimes the parcellation is not correct (e.g. a part of a gyrus is incorrectly labeled). i changed the sulcal labels near the incorrect parcellation (as the gyral parcellation heavily depends on the sulcal...

Hi, we're using version BV4.1. we want to export .tex files into Matlab. we searched the forum and did not find a (clear) answer. we found this document: http://brainvisa.info/doc/documents-4.1/formats/tex.pdf how can we convert .tex into ascii (possibly using AimsFileConvert, but what's the *exact*...

Hi,

thanks. i guess it's also possible outside BrainVisa (e.g. Matlab), i'll try that route first.
