Data Cursor as an input for a function

Hi,

I am writing a function that process a certain region (rectangular) of an image and I am trying to make the function show me the image in order to define the processing area by clicking on it the two points (X1,y1 , x2,y2) with data cursor.

an example of the function is:

function [ NormIntensityTime ] = NormIntensityTime( ImName_dir, yPx, xPx )

ImName_dir = 'C:\Users\Lab\...\Preprocessed\Str\020\test020_7\*.tif';

yPx = 40:134

xPx = 600:1100

etc...

Thanks a lot,

Andreas

or perhaps uigetfile() is what you want to select the file.

Once you have imread() the file, then image() or imshow() to get it to display.

However, you should not be using data cursor mode to define regions. You should look at imrect() or ginput()

Thank you very much for the answer! I think the ginput() function is the one I need.
