MATLAB: Error reading .mat file

error load .mat file

Hi, I have a .mat file which is produced by MIPAV and for some reason matlab cannot load it, here's the error message. Just wondering if anyone seen this before?
Number of columns on line 2 of ASCII file /Users/fiona/Desktop/_801_smask.mat
must be the same as previous lines.
Error in uiimport/runImportdata (line 467)
datastruct = load('-ascii', fileAbsolutePath);
Error in uiimport/gatherFilePreviewData (line 435)
[datastruct, textDelimiter, headerLines]= runImportdata(fileAbsolutePath,
type);
Error in uiimport (line 245)
gatherFilePreviewData(fileAbsolutePath);

MIPAV wrote a dud file.
Open that file in any reliable text editor, and you will find that it contains the text "MIPAV is writing a .mat file" and then the null character repeated 1247525 times, along with a few other assorted characters for variety:
It does not look much like a valid .mat file.
