Matlab open dialog showing grayed out files

Question

I am using this snippet of code to call an 'open file' dialog box in Matlab.

[img_file,img_path,filt] = uigetfile({ ...

        '*.bff*;*.REC*;*.mat*','Our Image Files (*.bff, *.REC, *.mat)'; ...

        '*.bff*','bff Files (*.bff)'; ...

        '*.REC*','PAR-REC Files (*.REC)'; ...

        '*.mat*','mat Files (*.mat)'}, ...

        'Select An Image File');

if filt==0

    return

end

The dialog opens, but .mat files appear grayed out (and unclickable).

I am using Matlab 7.13.0.564 on Mac Snow Leopard.

Any ideas what I'm doing wrong?

Answer 1

The problem is the wildcard * after the file extension (eg *.mat* ) The code cannot find any files that satisfy this condition - because for your .mat -files there is no additional character.
Hence, just use a wildcard before the file extension: *.mat
