Question about electrode implantation

[Raymundo.Cassani]

@anaskhan07

I was wondering if the brainstorm toolbox function "channel_project_scalp" is what brainstorm does when you click the dropdown menu for "Contacts" and select "project on cortex"

The function channel_project_scalp() is the one that is used, with the arguments:

• Vertices: Vertices from the Subject's default Cortex surface
• ChanLoc: Location of the electrodes

The menu Project on cortex calls the function ProjectContacts() in panel_ieeg.m using 'cortexmask' as surface. See the code here
