decodeOBJ reads Mayo Clinic Analyze 6.0 ROI Object Map format (*.OBJ) files.

I spent about an hour examining Object Maps in a hex editor until I came up with a way to parse them. Warning, if you're not using Analyze 6.0 on Windows and Matlab R14 SP1 then I have no clue if this will work.

Usage: [objectmap,header] = decodeOBJ(file);

[objectmap,header] = decodeOBJ('C:\foo\bar.obj');

I use Analyze to manually trace ROIs in my data and then I load the Object Maps and do statistical tests on them in matlab.
