I'm creating a GUI where the user select's a disease from a panel which then shows them the EEG reading of that disease. However, I'm having trouble with writing the code to upload the image. I saved the image under the name Alzheimers_EEG.png and saved it on my MATLAB folder but when I write this code:
A = imread('Alzheimers_EEG.png');
The following ERROR shows up in my Command Window:
Error using imread>get_full_filename (line 569)
File "Alzheimers_EEG.png" does not exist.
Error in imread (line 371)
fullname = get_full_filename(filename);
Error in untitled3 (line 1)
A = imread('Alzheimers_EEG.png');
How can I fix this?

You should specify the full path, e.g.,
A = imread('C:\Users\Cristina\Research\Alzheimers_EEG.png');
or whatever it is, because MATLAB is looking for Alzheimers.png in its working directory, which doesn't seem to be the directory where that file is located.

Hi Cristina,
As per my understanding, "Alzheimers_EEG.png" does not exist in the current directory or search path. Please check once the image name and location to resolve this issue.
Please refer the link for reading an image from a graphics file.
