It would fail :( It could easily be remedied with another assertion: assert(all(size(size(wl))==size(size(master))),'Your selections don''t have the same number dimensions!!'); %Note a more polite and helpful comment. Though rude comments are the best way to get a laugh out of your coworkers!

Though rude comments are the best way to get a laugh out of your coworkers! You could one-line it with: assert(isequal(size(wl),size(master)),'The sizes are not the same'); Though it's probably more helpful for error tracking purposes to have two with more descriptive messages.

Is there any reason you're not using uigetfile or some similar approach? The images are opened based upon the user selection in a listbox. Since multiple images are opened (up to 15) and have their spectral data averaged and displayed on the same plot, isn't it the best way??? Maxx And thanks for the help Sean, Walter, and us. I did not use the assert function, but it lead to the right answer. Unfortunately, I did tone down my message. Which leads me to another syntax error...how can I incorporate sprintf into the error dialog multiple times? I'm working on it now - just need sprintf with ~tab~ to work on the two lines shown... if rows==0; errordlg(sprintf{'No %s data on file. Troubleshoot:',tab} char(10)... {' 1) Update PSL Master Sheet with latest data' char(10)... ' 2) Check spelling of filenames in PSL Master Sheet ' char(10)... }sprintf{'Please uncheck %s box to continue.',tab}),'FCI Data Error'); return

You can include several lines of error dialog by using {} around the list. errordlg({sprintf('No %s data on file. Troubleshoot:', tab) ... sprintf('\t1) Update PSL Master Sheet)' }); I am not certain, though, that \t will produce more than a small bit of empty space for errordlg() purposes.

I'm sorry, tab is a variable that represents an acquisition type (fci, rci, or swir). The problem is with char(10). It doesn't seem to like being on either side of (),{}... |
