Subject: Difference between Matlab and MEDx
> Dear SPM users,
>
> I compared multisubjects and covariate only analysis results of PET
> activation study on Matlab and MEDx.
> Almost results are equal, but there is a little difference on one
analysis.
> Matlab result has area 11 activation only, but MEDx result shows area 10
and
> 11 activated.
> Clusters of MEDx result is smaller than Matlab's one.
> Spatial preprocessing, design matrix, and etc are same.
> Subtraction analysis comparison has no differences.
> And comparison between Matlab5.3 and 6.0 has no differences, too.
> Is this difference true?
