Dipoli issues

[Vladimir Litvak]

Dear Paul,

Note that there is also the bemcp toolbox distributed with Fieldtrip
that should be easy to compile on Linux. I compared it with OpenMEEG
on SPM canonical mesh and there are only differences for a small
number of vertices close to the boundary. According to Christophe
Phillips who wrote the toolbox as long as you stay more than one mesh
edge length away from the inner skull boundary there should be no
problem and it runs much faster than OpenMEEG (don't know about
dipoli).

Best,

Vladimir
