The y_* files were previously deleted, so that was not the problem. We managed to find a solution,
but not an explanation: spm5 r1111 works perfectly, r1782 fails. There appears to be some
incompatibility between the r1782 mex files and our hardware that recompiling does not solve. Hope
this helps someone else out there. Thanks for all your help John.
Cheers,
