I have a question about the display and file contents of my obtained source models.
I have a dSPM source model that is time averaged (and after that normalised). This way I have one dSPM model for one measurement. I can display the source model on the cortex of the brain or on the spheres perfectly.
For further analysis I was hoping to get 2D projections of the source model. Sort of like 'unfolding' the cortex and displaying it as a flat surface (so that the z-coordinates of every point is zero). Is this possible in Brainstorm?
Moreover, I had a question about the output files. In my case the ImageGridAmp field is 15002 x 2. Which makes sense, since I chose to use 15000 vertices. If I want to use this data file to get to a 2D representation/image of the source model on the cortex, how do I know which value goes in which location?
