Anisotropic conductivities for use in duneuro

Hi,
This may not be relevant to brainstorm.

With respect to duneuro if someone knows whats the file format for providing the anisotropic conductivities? or how duneuro accepts anisotropic conductivities.

Saima Safdar

Hi,
The brainstorm-FEM pipeline supports the anisotropic computation.

Please refer to the online tutorials related to the FEM and the fem tensors, you can find all the information.

You can also check this paper: https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11595/1159554/Realistic-head-modeling-of-electromagnetic-brain-activity--an-integrated/10.1117/12.2580935.short?SSO=1

Hi Saima,

regarding your question on Github,
I think the best solution is to follow and reproduce the data within this tutorial:
https://neuroimage.usc.edu/brainstorm/Tutorials/FemTensors

The MRI and the DWI are open source.

If you would like I can share the final files as well.

best,

yes please that would be great if you can share final files.

Thank you

Hi Saima,

Here is a folder with an example of the of the DTI-EIG structure where the eigen values and vectors are stored, and the associated FEM mesh with the computed tensors:

You can get these data if you follow the first part of this tutorial: Tutorials/FemMedianNerve - Brainstorm
