[FieldTrip] MEG forward problem

Dear fieldtrip developers,


In MEG forward problem computations (in ft_compute_leadfield or in its
subfunctions), do you numerically integrate the MEG signal over the coil
area or a single point is used for each coil?


I found some functions in the fieldtrip's SVN (trunc) version (on
googlecode), which are not available in the daily releases on the ftp server
(e.g. ft_surfacecheck). Is it safe to use those functions (I understand that
the toolbox is released under GPL)?


Thanks in advance
