[Eeglablist] topoplot incompatibility

[Simon-Shlomo Poil]

Dear Angel,

To me it sounds like an issue with the function 'griddata' ..

Could you check the following lines in your Topoplot function.
 Do
edit topoplot

and check that line 956 to 962 are:
 try
      [Xi,Yi,Zi] = griddata(inty,intx,double(intValues),yi',xi,'v4'); %
interpolate data
      [Xi,Yi,ZiC] = griddata(inty,intx,double(intContourVals),yi',xi,'v4');
% interpolate data
  catch,
      [Xi,Yi,Zi] = griddata(inty,intx,intValues',yi,xi'); % interpolate
data (Octave)
      [Xi,Yi,ZiC] = griddata(inty,intx,intContourVals',yi,xi'); %
interpolate data
  end;

If you use the EEGlab version packed with NBT you should have those lines..
