uigetfolder returns 0 for existing folders

I've recently upgraded to OS X El Capitan and I am having an issue with the uiget functions. Matlab appears to be randomly able to find certain folders and not others. I have checked all file permissions and gone as far as duplicating permissions for files that uiget is able to find, on files it cannot without any success. The issue is not present if I launch matlab as a super-user, which suggests this is purely a permissions issue. Has anyone else had this issue and found a resolution?

As an experiment, try telling OS-X to show hidden files: http://ianlunn.co.uk/articles/quickly-showhide-hidden-files-mac-os-x-mavericks/, and related http://apple.stackexchange.com/questions/186376/hotkey-to-show-hidden-files-and-folders-in-file-open-dialog

No change. I actually have my system configured to show hidden files. I tried turning it OFF and then back ON without success. I tested the uigetfolder in both cases.

Could you give some examples of folders it cannot find?

Have you tried

ls -dle

on the directory to check if it has ACLs associated?

If you make a copy of the directory at the same level, is the copy also hidden? Copies made by copy/paste in the finder, for one, and copies made by some lower level method such as (shell level)

mkdir TestDirectory
cd OddDirectory
find . -depth -print0 | cpio -pdm0 ../TestDirectory
