Hello,

I tried to run gPPI and couldn't get it to work. The reason was that the file 'path\to\spm12\toolbox\PPPIv13.1\PPPIv13\contains.m' overrides an existing Matlab function. To fix the problem, I renamed the file 'path\to\spm12\toolbox\PPPIv13.1\PPPIv13\contains.m' to contains2, changed the function name inside the file to 'contains2', and replaced all calls to 'contains' in the package code to calls to 'contains2' (functions that call 'contains' are: 'spm_estimate_ppi', 'createVec', and 'timeseries_extract').

Hope this will be useful,

Wanted to say thank you for that hint! Icould not get the toolbox run (I tried SPM8 and SPM12; Matlab2019 and Matlab2018).

This was the error:

Operands to the || and && operators must be convertible to logical scalar values.
Error in dlmwrite (line 133)

Error in PPPI (line 861)

And changing the function to contains2 helped! Thanks!

Hi,

I had exactly the same problem / received the same error message  using Matlab R2017B and was very happy to find this thread and fix. Unfortunately, I could not solve the problem. I renamed the function and its calls to "contains2" as Matan suggested. However, I couldn't find the call of "contains" in the function 'path\to\spm12\toolbox\PPPI\timeseries_extract.m'. Any help / suggestions would be appreciated.

Thanks a lot!
