Dear all,

I wanted to start using the gPPI Toolbox and downloaded the toolbox.
In order to instal the toolbox, I followed the instructions in the manual provided on the webpage.

However, when testing the toolbox installation, my output is not equivalent with the README.txt file (hence, not properly working).
I always receive this error message at the end of all calculations:

Valid Contrast
Valid Contrast
contrast image 9 : ...written con_0009.nii
spm{T} image 9 : ...written spmT_0009.nii
contrast image 10 : ...written con_0010.nii
spm{T} image 10 : ...written spmT_0010.nii
Moving Contrast Images
error moving contrast PPI_PPI_contrast1
error moving contrast PPI_PPI_contrast1
Moving Contrast Images
error moving contrast PPI_PPI_contrast2
error moving contrast PPI_PPI_contrast2

I already browsed this forum to find answers, and found entries of S. Sheldon (Date: 03.11.2015) and Yangyang Zhang (Date: 25.05.2017) with the same error message. The provided .m-files (spm_contrasts_PPI.m) also didn't fix the error in my case.

What might be the problem?

Thank you all in advance.
Best,
Nadine

Could you provide me with the version of spm_contrasts_PPI.m that you are using?

Thank you for your reply.
I attached the .m-file.

Please rename the attached mat-file to spm_contrasts_ppi.m and replace the existing file. This should fix the issue.
