how to save the pixel location in files

how to save the pixel location in files my aim is to ground truth thousands of images with the pixel location (position) just Y coordinate , so after reading the image and getting the pixel info (impixelregion) I want to save the position that I click on in a file with the same name as the image name I know that I can save this position by right click and copy it in a file but this is really time consuming with lots of images

thanks

Use save() to save in a proprietary binary MATLAB format file. Or you can use fprintf() to save them to a text file.

yes , I did that , but my problem is how to get the location of the pixel and save it in just one click , by only one click I want this location to be saved in a file //////////// code////////// I = imread(image) impixelinfo p = (a variable to handle the position of pixel that I click on) f = fopen('file','w'); fprint (f, p); fclose(d);

thanks

[x y] = ginput(1); % (x,y) is (column, row), not (row, column)
