MATLAB Invalid MEX File

Question

So I'm running software I downloaded for analyzing the position of fluorescent proteins in microscopy images. The software is called plusTipTracker , and it runs off MATLAB.

So the first function (detecting 'spots' in the images) works fine, but the second function ("track spots") fails. In particular, it seems to be an error with a MEX file:

??? Invalid MEX-file
'/Users/ethanbuchman/Documents/MATLAB/plusTipTracker_1pt1pt3_2012-07-07/software/createDistanceMatrix.mexmaci64':
dlopen(/Users/ethanbuchman/Documents/MATLAB/plusTipTracker_1pt1pt3_2012-07-07/software/createDistanceMatrix.mexmaci64,
1): no suitable image found.  Did find:
    /Users/ethanbuchman/Documents/MATLAB/plusTipTracker_1pt1pt3_2012-07-07/software/createDistanceMatrix.mexmaci64:
        unknown required load command 0x80000022.

I can locate this file in the software folder i downloaded. There are actually multiple versions, each with a different extension (eg. .mexa64, .mexmaci, .mexmaci64, etc.). There's also a .dll file. While there are other mex files in the folder, each with multiple extensions, none of the others have an associated dll file. Not sure if that's relevant.

But I have no idea what to do about this.

Im on MacOSX 10.5.8 using Matlab R2010b.

Any insight would be greatly appreciated. Thanks.

From what I'm reading here , it seems like the MEX file was compiled for a different version of Mac OS. Can you recompile the MEX files and DLL on your own system?
