Source analysis group comparison

[albertobenelli21]

Dear experts,

my project involves the comparison of 3 groups of subjects. For each subject I have an EEG (resting state) file and also have the respective MRI scans already segmented with freesurfer, DTI and rsfMRI scans.

I would like to know if it would be possible:

1. Automatically import all the subjects together (MRI, DTI and EEG) without having to do it manually one by one
2. Automatically create and display source files for each subject
3. Visualize the EEG on GM surface but also related to WM tracts.
4. Automatically create and display dipoles for each subject
5. Also, having rsfMRI files, is it possible to visualize, also doing statistical analysis, the variation of the BOLD signal along with the spectral power density of the EEG? so as to see if there is a match

Thank you in advance for your help

Alberto

Hi Alberto,

@albertobenelli21

1. Automatically import all the subjects together (MRI, DTI and EEG) without having to do it manually one by one

This can be done by scripting the steps, this is well documented in this tutorial:
https://neuroimage.usc.edu/brainstorm/Tutorials/Scripting
Regarding DTI, Brainstorm supports importing the fibers file as TrackVis (*.trk), check this link:
https://neuroimage.usc.edu/brainstorm/Tutorials/FiberConnectivity

2. Automatically create and display source files for each subject

Same as in point 1, check the scripting tutorial

3. Visualize the EEG on GM surface but also related to WM tracts.

Yes, it is possible to visualize the results from EEG-based source localization on the cortex. However, for the WM tracts what kind of visualization do you have in mind?

4. Automatically create and display dipoles for each subject

Same as points 1 and 2, this can be done with scripting

5. Also, having rsfMRI files, is it possible to visualize, also doing statistical analysis, the variation of the BOLD signal along with the spectral power density of the EEG? so as to see if there is a match

For the moment Brainstorm does not support fMRI data.

The system indicates this account may be a duplicated of @albertobenelli, is this correct?
Let us know if this is the case and you want to merge these two accounts.

Hi Raymundo,

Thank you for your clarification.

1. In order to upload the DTI file (.nii file) should I convert it into a .trk before? cause I don't know how to do it. I can export tracts one by one saving them as .trk files, but I'm not sure how to save the DTI scan as .trk file.
2. When I visualize the EEG SPD I'd like to see which WM tracts, under the GM, are involved in.

Thank you again,

Alberto
