function fnc_MyTopo_giga2(rel,sel,M1,lims,cur,ticks,t_e,HeadModel,ELECTRODE_HEIGHT,tex,Color,GS)
%% Function to graph the different topoplots of the database. %%
% rel       -   Vector of weights 1xN.
% pos       -   Positions vector Nx2.
% sel       -   Channels selection.
% label     -   tag cell Nx1.
% lims      -   vector colorbar limits [min max].
% cur       -   boolean enables contour lines 1,0.
% ticks     -   ability to plot Boolean labels 1,0.
% t_e       -   size of the electrodes.
% database  -   selected database.
% HeadModel -   model of the human head.
% tex       -   ability to plot labels of channels 1,0.
% Example:
%               vector de los pesos.
%               tex = 0;
%               load('electrodesBCICIV2a.mat') 
%               load('HeadModel.mat')          % model of the head.
%               t_e = 15;                      % size electrodes.
%               M1.xy = elec_pos;              % position of channels.
%               M1.lab = Channels;             % names of channels.
%               sel = 1:22;                    % channels selection.
%               rel = ones(1,64);              % relevance of channels.
