Use this code. Adapt it to reflect the actual filename of your image and your Photoshop location.

clc;
%-----------------------------------------------------------------------------
% Get the name of the image file.  Get the full filename, with path prepended.
% Use a standard MATLAB color demo image.
folder = fullfile(matlabroot, '\toolbox\images\imdemos');
baseFileName = 'peppers.png';
% Get the full filename, with path prepended.
fullImageFileName = fullfile(folder, baseFileName);
if ~exist(fullImageFileName, 'file')
  % Didn't find image.  Alert user.
  errorMessage = sprintf('Error: image\n%s\ndoes not exist.', fullImageFileName);
  uiwait(warndlg(errorMessage));
  return;
end
% Check to see that Photoshop executable exists.
editorFullFileName = 'C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Photoshop.exe';
if ~exist(editorFullFileName, 'file')
  errorMessage = sprintf('Cannot find the Photoshop program.\n%s', editorFullFileName);
  uiwait(warndlg(errorMessage));
  return;
end
% Now run the Photoshop program, passing in the image filename.
% First construct the command line for the system() function.
% Enclose all filenames in double quotes because we may have spaces in the filenames.
arguments = sprintf('"%s"', fullImageFileName);
commandLine = sprintf('"%s" %s', editorFullFileName, arguments);
fprintf('%s', commandLine);
% Now launch the Photoshop program using the "system()" function.
system(commandLine);

MATLAB: I have a folder of .tif images that need to be converted to a different format for downstream analysis

Hi,

I think your input tif files are in single format whereas your output file format which is jpeg doesn't support single format while using imwrite (you can find using help imwrite in the 'fmt' of the file output section)

You can do this instead. either save them in a different file format let us say 'bmp', 'jp2' or 'png'. Else you can do the following thing by converting your input image from single format to unsigned integer 8 (uint8).

% Specify the folder where the files live.
myFolder = '/Users/masonlien/Desktop/PhD/Drone/2020/test';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(myFolder)
	errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease select another folder.', myFolder);
	uiwait(warndlg(errorMessage));
	myFolder = uigetdir();
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.tif'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
numFiles = length(theFiles);
if numFiles == 0
	warningMessage = sprintf('Warning: no TIFF images found in the folder:\n%s', myFolder);
	uiwait(warnuser(warningMessage));
	return;
end
for k = 1 : numFiles
	baseFileName = theFiles(k).name;
	fullFileName = fullfile(myFolder, baseFileName);
	fprintf('Now reading %s (#%d of %d).\n', fullFileName, k, numFiles);
    % such as reading it in as an image array with imread()
    
    % Change made here 
	imageArray = uint8(imread((fullFileName)));
	imshow(imageArray);  % Display image.
	caption = sprintf('%s (#%d of %d)', fullFileName, k, numFiles);
	title(caption, 'FontSize', 14, 'Interpreter', 'none');
	drawnow; % Force display to update immediately.
	% Write it out as a PNG file.
	baseFileName = strrep(lower(baseFileName), '.tif', '.jpg');
	outputFileName = fullfile(myFolder, baseFileName);
	fprintf(1, 'Now writing %s\n', outputFileName);
 	imwrite(imageArray, outputFileName);
end

MATLAB: Error using imread (line 368) ; File “…” does not exist

Hi. change your current folder to myFolder:

cd(myFolder)

or use this:

im1 = imread([myFolder pngfiles(1).name])
