Dear gPPI experts

I am currently investigating associative memory functioning in 23 subjects with two tasks "Contingent", "Non-Contingnet". The script that I'm currently trying to run outputs the following error message:

PPPI inputs were specified correctly, but failed error checking for dependencies. This is likely a bug in the program.
errorvals saved to errorvals.mat

I made sure that the paths are set correctly, however, I don't know if all parameters that I want specified are done so correctly.
Consulting the errorvals.mat file unfortunately did not provide any additional information apart from the above error text.

Is there a way to check for which specific parameters are or are not specified correctly?

I have attached my script in plain text for reference.

Any help or suggestions on this issue are greatly appreciated.

Kind Regards
Marko

Hi Marko,

This is a tricky one as it should not have happened - hence the error message.
One possibility -- Line 563 in PPPI_checkstruct.m should changed from tmpTasks=P.Tasks{2:end}; to tmpTasks=P.Tasks(2:end); 
This is invoked because P.contrasts was not specified.

If that doesn't work, can you run on a single subject and do the following:
(1) Provide any screen output.
(2) Load strcat(P.subject,'_PPIstructure.mat'); [P, tmperror]=PPPIinputsvalid(P)
(3) Provide any additional screen output

Additionally, to check the general PPPI functionality on your system, I'd suggest you try running PPI on the test dataset provided on this website. Let me know if you get the same error.

Doing all of the above should help figure out what setting is missing.

Best,
Donald
