Yes David I found that the manual also states that there are types not
supported by Octave (though in less detail than your email).  I don't have
access to MatLab right now, but I will be able to test tomorrow to be
certain of what type I am trying to import.

John,  I am not sure there is a bug because I am not sure what kind of
file I am trying to import (publicly available dataset).  I put a single
.mat file on my webserver if anyone is interested in trying this out (I
will be able to tomorrow):

http://metm.org/export/annotation_0001.mat

If this seems like a bug I will be happy to submit it,

Thanks for the pointers,
