Hello,

I tried to open this .mat file: https://dl.dropboxusercontent.com/u/20782274/MOTNL.MAT

But I get the following error:

Error using load
Unknown text on line number 1 of ASCII file
<some path>/MOTNL.MAT
"MATLAB".

I opened this .mat file in notepad and I saw it was created in Matlab 5.0 in 1999. So I believe this is a conversion error? So if this is the case could anyone maybe upconvert it? So I can open it with Matlab 2012a?

Do you want the .mat file I generated? There are a LOT of different variables saved in the workspace

If you are willing to do that, yes I would like that.

Try

load('MOTNL.MAT', '-mat')

Remember, Linux is case-sensitive, so possibly the .MAT is throwing it off.
