Minor bug in fletcher16.m

[LSWSL]

Dear Dr. Allefeld,
When the ‘date’ in 'spm.mat' contains chinese characters（it is due to the system's language setting）, Funcation 'Checksum' will prompt the UID is ‘invalid data’.
I removed the call to the ‘date’ by modifying the code in cvManovaSearchlight.m（line 56,57）：

    uid = gencode({‘SPM.mat’ , ...
    slRadius, Cs, permute, lambda});

after that it runs smoothly, maybe there is a better way to solve the bug.
Thanks sincerely for your work.

best
Liu

Sorry for the extremely late answer!

The problem is, I have no idea how to fix this. Theoretically, getfield(dir('SPM.mat'), 'date') should return a regular Matlab string, which is then translated into numbers by data = double(data(:)); in fletcher16. The only idea I have is that maybe the SPM.mat file was created on a system with a different locale than that on which cvmanova is run, leading to a string with invalid data.

If you'd like me to look into this further, you could send me the SPM.mat file, e.g. through a filesharing service.

Also, could you copy & paste the exact and complete error message?
And which version of Matlab & SPM do you use?
