Hello,

I am trying to use the PPPIv13 package to estimate gPPI models using SPM12. I previously did this with SPM8. I specified to SPM version using 'P.SPMver = 12;', but I am getting the following error:

PROGRAM ABORTED:
You must use SPM8 to process your data; however, you can use SPM.mat files
generated with SPM2 or SPM5. In these cases, simply specify the option SPMver
in single qoutes followed by a comma and the version number.

Is there something else I need to do to use the PPPI package in SPM12?

Any and all advice would be great! I haven't found any specific posts on this issue.

Thank you in advance,
Arianna
