How to load an image to a figure using uigetfile/imread?
Novice coder here with a question that I am certain there will be an easy answer to - it just escapes me at the moment... I am simply trying to display an image that I select from my PC's location, in a figure for further analysis. I actually have the analysis code working, but the problem I am having is that when I use uigetfile to provide the 'file look-up', I can navigate to the file, get the figure to launch, but the image then doesn't write to the figure. My code thus far is: [filename, pathname] = uigetfile(... {'*.jpg; *.JPG; *.jpeg; *.JPEG; *.img; *.IMG; *.tif; *.TIF; *.tiff, *.TIFF','Supported Files (*.jpg,*.img,*.tiff,)'; ... '*.jpg','jpg Files (*.jpg)';... '*.JPG','JPG Files (*.JPG)';... '*.jpeg','jpeg Files (*.jpeg)';... '*.JPEG','JPEG Files (*.JPEG)';... '*.img','img Files (*.img)';... '*.IMG','IMG Files (*.IMG)';... '*.tif','tif Files (*.tif)';... '*.TIF','TIF Files (*.TIF)';... '*.tiff','tiff Files (*.tiff)';... '*.TIFF','TIFF Files (*.TIFF)'},... 'MultiSelect', 'on'); % Error check - if no filename there is an error if isequal(filename,0) error(' Load Error: No files selected! Load cancelled.') else end % launch the figure box figure imagefilename = imgfile(filename,pathname); c = imread(imagefilename); image(c) axis image grid on I'm certain the problem is the bit after I launch the figure, but I have tried several different combinations of syntax, but just cant get it right.

I think you want fullfile() instead of imgfile().
% Have user browse for a file, from a specified "starting folder." % For convenience in browsing, set a starting folder from which to browse. startingFolder = 'C:\Program Files\MATLAB'; if ~exist(startingFolder, 'dir') % If that folder doesn't exist, just start in the current folder. startingFolder = pwd; end % Get the name of the file that the user wants to use. defaultFileName = fullfile(startingFolder, '*.*'); [baseFileName, folder] = uigetfile(defaultFileName, 'Select a file'); if baseFileName == 0 % User clicked the Cancel button. return; end fullFileName = fullfile(folder, baseFileName) myImage = imread(fullFileName); imshow(myImage);
