Hi,

I've been having issues projecting source estimates onto an MRI. I discovered that several of my components (vol, grad, grid) did not exist in the same coordinate space. Some were in mm and some in cm. After I resolved these issues, I was able to use headmodelplot to verify that everything was correct (see attached screenshot). I then attempted source localization using lcmv and noticed that that the projected activation existed in the incorrect orientation (see second attached screenshot). I'm not sure what I'm doing wrong as all of my components are in the correct space. I also tried to use the interactive option of sourceplot to correctly set n,l,r but that didn't seem to change anything. I'm sure it is something very simple that I am overlooking but any help would be much appreciated.

Thank you,
-Tony
