error loading Matlab 5.0 binary : invalid element type

[Marco Scoffier]

Hello all,

I have had generally good luck opening MatLab files with octave, however I
now have a whole dataset which is giving me the same error:

octave:3> load annotation_0001.mat 
error: load: invalid element type
error: load: trouble reading binary file `annotation_0001.mat'
octave:3> load -mat-binary annotation_0001.mat 
error: load: invalid element type
error: load: trouble reading binary file `annotation_0001.mat'

The data comes from the Annotations for the Caltech 101 data used for
Computer Vision: http://www.vision.caltech.edu/feifeili/Datasets.htm

I can post a single example of a file if it helps to track down the source
of the error.  (not sure about attaching files to this list). The
beginning of the first line in file is:

MATLAB 5.0 MAT-file, Platform: PCWIN, Created on: Tue Nov 09 11:34:14 2004 

Identical to files I have opened successfully in the past.

Thanks for any pointers,
