Hi I need help using the Data cursor tool on an image. I need to get the index number for some hyperspectral images for data analysis but I need to be able to draw an Area and not just get the individual pixel information. Can someone explain to a new Matlab user (me) how to accomplish this?

sounds like you want to designate a region of interest (ROI) which requires the image processing toolbox

It shouldn't be difficult to create a simple ROI tool using ginput()

There are probably adaptable tools in the MATLAB File Exchange.
