Exporting atlas information in Excel or CSV format

[Shadi]

Hello Brainstorm professionals

I have created a new atlas for my data from Desikan Killiany and used it for my connectivity analysis. now I need to have its data for later analysis out of Brainstorm. I need its data (including row names and x, y, z coordinates of each area) to be included in the exported file (ex. a sheet with 4 columns). but I couldn’t find these data on the exported file in the workspace. would you please guide me?

I need its data (including row names and x, y, z coordinates of each area) to be included in the exported file (ex. a sheet with 4 columns)

In the Atlas that you created, each of the Scouts have a Label (which may be the one you refer as "row names"). The Scouts do not really have xyz coordinates, as they are set of vertex indices. However there is a field called Seed that is the vertex index for the central point of the Scout.

All this information is in the Atlas field of the default cortex (in green). See these links:

• https://neuroimage.usc.edu/brainstorm/Tutorials/ExploreAnatomy#On_the_hard_drive:_Surface
• https://neuroimage.usc.edu/brainstorm/Tutorials/Scouts#On_the_hard_drive

The relationship between indices and xyz coordinates (in the SCS) is Vertices field of the surface.

Once you have that imformation, exporting it as a Excel or .csv can be done with standard Matlab functions.
