mesh_write_brainstorm

 mesh_write_brainstorm - Save eeg toolbox meshes to brainstorm format

 USEAGE: mesh_write_brainstorm(p)
 
 This routine saves each mesh in p.mesh.data into the correct 
 structure format required in brainstorm.
 
 The workspace variables created are saved, in the brainstorm 
 file format, into p.mesh.file with a '.mat' extension.
 
 The variables from this file can be loaded using the matlab 'load' 
 command. To plot the default cortex, skull & scalp BrainStorm data:

 Hpatch1 = patch('Vertices',Vertices{1}','Faces',Faces{1},...
                 'EdgeColor',[.6 .6 .6],'FaceColor',[0.9 0.9 0.9]);
 Hpatch2 = patch('Vertices',Vertices{2}','Faces',Faces{2},...
                 'EdgeColor',[.6 .6 .6],'FaceColor',[0.9 0.9 0.9]);
 Hpatch3 = patch('Vertices',Vertices{3}','Faces',Faces{3},...
                 'EdgeColor',[.6 .6 .6],'FaceColor',[0.9 0.9 0.9]);

 and content of the subjecttess variables.
