Inputm shift my coordinates

Hello,

I'm trying to extract coordinate of some points on my map, and to plot green point at extracted position (for visual comfort).

I use the inputm function because it gives me what I look for (latitude and longitude). The problem is my extracted latitude is shifted northward (my longitude is okay). I saw someone with the same problem but the question was never answered.

Here is my fig, 2 green points are on it. To understand better, when I click on the bot one (~16.5°N) it extract me coordinates of the top one (~17°N).

Here is my code :

if true
% code
if Extract=='yes' 
  button = 1;
  position=zeros(1,2);
  while sum(button) ~=3 % stop with right mouse click
      h=axesm('MapProjection','mercator','MapLatLimit',[latGz(1,1)...
      latGz(end,end)],'MapLonLimit',[lonGz(1,1) lonGz(end,end)]);
          [latpoint, lonpoint, button] = inputm(n,h);
          if button~=3 
          hold on 
            m_plot(lonpoint,latpoint,'g.','markers',20);
          end
          coord=[latpoint lonpoint];
          position=[position; coord];
  end
end

end

Does someone know how to fix it please ? M.

I found a solution, for people having the same issue in future, use ginput to extract pixel data and convert it in lat/lon with m_xy2ll. Still don't know why inputm shift northward ! M.
