Hi gPPi experts,

I tried gPPI with tutorial data with SPM12 (v6470, 03-Jun-2015). It has no problem when running through all tutorial scripts. However, when I update SPM12 to recent version (v6906, 20-Oct-2016) and run the same tutorial scripts. The gPPi halted when estimated gPPI design. Here is the error message:

SPM12: spm_spm (v6842) 16:09:54 - 29/11/2016
========================================================================

SPM12: spm_est_non_sphericity (v6827) 16:09:55 - 29/11/2016
========================================================================
Estimation Failed
Warning: Missing conditions!!! Invalid Contrast
Invalid Contrast
PPI Contrasts were not estimated for some reason.

When I try spm_spm(SPM) with gPPI SPM.mat. It goes smoothly without error. It seems that it is not the problem from SPM12's estimation.

The SPM12 v6906 change the version number of spm_spm from v6015 to v6842, and change spm_est_non_sphericity from v6015 to v6827. I guess the updated spm_spm or spm_est_non_sphericity cannot pass variables to PPPI. Does anyone know how to solve this problem?

Many thanks,
