Trouble Opening .dat Files in R2013b

I have a program that saves all my environment variables to a .dat file once per iteration. This way, I can open up these variables at a later time to make plots, etc.

In R2010b, I get a simple dialog box when I double click the .dat file to open. It looks like this:

However, I recently upgraded to R2013b, and now the uiopen dialog box is completely different and I can't figure out how to get my variables to show up correctly:

I've tried all the various options involving column delimiters and so forth, but nothing I've tried gives me my original variables back. Any suggestions?

Thanks!

It appears that it is a MAT file that has a dat file extension.

Could you try the following on the command line:

>> load('thing.dat')

or try renaming the file from thing.dat to thing.mat and then double clicking on it in the current folder browser.

Huh, this seems to work. I've been using .dat for a couple years with this project and 2010b never complained. Thanks!
