I am trying to get a selection of hits from SOM map, for this object I use "som_select" function. However, I can't get GUI, I get the next answer:

som_select(150);
??? Error using ==> getfield at 31
Not enough input arguments.
Error in ==> som_select>draw_colorselection at 354
for i=0:getfield(size(rep_y,2))-1, rep_x(:,i+1)=rep_x(:,i+1)+i; end
Error in ==> som_select at 153
draw_colorselection(c_names,c_colors);

I have used SOM struct, initial dataset, size of SOM struct, size of initial datasets…but these aren’t successful input arguments…

Somebody know other way to select hits of my SOM, an example o turorial to practice?

thanks

Just to check, did you follow this procedure prior to using som_select?

From som_select:
"For the function to work, the plot in the
% axes must have been created with the
% SOM_CPLANE function (or SOM_SHOW)"
