function [p] = mesh_write(p)

% MESH_WRITE - a switch yard for several mesh writing functions
% 
% Useage: [p] = mesh_write(p)
% 
% p is a parameter structure (see eeg_toolbox_defaults for
% more details). In this function, it should contain mesh data
% in p.mesh.data and the following string fields:
% 
%       p.mesh.path - the directory location of the file to load
%       p.mesh.file - the name of the file to load
%       p.mesh.type - the file formats (case insensitive) are:
% 
%                    'emse'
%                    'brainstorm'
%                    'ascii' or 'freesurfer' for *.asc file
%                    'fs_surf' for freesurfer binary surface
%                    'fs_curv' for freesurfer binary curvature
%                    'fs_overlay' for freesurfer binary overlay (.w)
% 
% If you have a file format you would like supported, please email
% the author with an example and description of the format.  The 
% file formats supported here are described in more detail at 
% their respective websites:

%       EMSE:       http://www.sourcesignal.com
