Is there a command that simulates ginput?

My question here is that I want to use ginput to select 2 datapoint on a figure. But after the first figure, there are 19 more figures (who look alike) in my program that will pop up. So now I'm searching for a command that simulates 'ginput' so I don't need to click to select the starting and ending point for example.

You could use the java.awt.Robot but this workflow sounds horrible. What are you trying to do? Can you give a minimal working example?

for welke_pp=1:aantal_pp % for 5 subjects
...
for i_testen=1:length(data_stair_rise) %for 4 measurements
RANK = data_stair_rise(welke_pp,i_testen).VideoSignals(:, strcmp('RANK', data_stair_rise(welke_pp, i_testen).VideoSignals_headers)); %extract data
figure;
plot(RANK)
ylabel('Distance');
xlabel('Datapoint');
title('Walking stairs')
legend({'Right ankle'});
xy = ginput(2);
Afstand_1schrede(welke_pp,i_testen) = xy(2,2)-xy(1,2); %distance of 1 step

Now I used the ginput command for all my subjects. That's a lot of figures. I want a code that automatically finds the points that I want to select: so, if I select 2 points, is there a command who can do this for?

You forgot to post an image. Perhaps there is something in your image that can be automatically found/identified and then you can record the coordinates that way. No way of telling until we see several photos that show the range of images you expect to encounter. For example, is the camera field of view fixed, or are your images of different scenes, or different viewpoints or zooms? Is the lighting consistent from image to image? Are any of the points to be found ever obstructed/occluded by the person climbing? These things need to be considered if you are to ever robustly find the marker points automatically.

In attachment are 6 figures. Each figure represent the 'right ankle marker'. Hope you can help me...

And what points on those get marked? The steep rising points? In the middle of the "sort of flat" points?

We need to select the contact point of the heel and the point one step further, so again the contact point of the same heel.
