Hi everyone,

we want to run a Stop-Signal-Task (SST). Unfortunately, we get an error message for the following line:
iscorrectresponse = [(values.expcondition == 1 && if(values.stimulus=40)trial.nstrial.response==values.leftkey else trial.nstrial.response==values.rightkey) ||
                        (values.expcondition == 2 && if(values.stimulus40)trial.nstrial.response==values.leftkey else trial.nstrial.response==values.rightkey)]

Expression ' if (values.stimulus<=90)trial.p_nstrial.response==values.leftkey else trial.p_nstrial.response==values.rightkey)||(values.expcondition==2&& if (values.stimulus>90)trial.p_nstrial.response==values.leftkey else trial.p_nstrial.response==values.rightkey)' is invalid. Unmatched parenthesis.

We would appreciate any help!

Best,

(1) The line

iscorrectresponse = [(values.expcondition == 1 && if(values.stimulus=40)trial.nstrial.response==values.leftkey else trial.nstrial.response==values.rightkey) ||
(values.expcondition == 2 && if(values.stimulus40)trial.nstrial.response==values.leftkey else trial.nstrial.response==values.rightkey)]


is not what the error message references.

Expression ' if (values.stimulus<=90)trial.p_nstrial.response==values.leftkey else trial.p_nstrial.response==values.rightkey)||(values.expcondition==2&& if (values.stimulus>90)trial.p_nstrial.response==values.leftkey else trial.p_nstrial.response==values.rightkey)' is invalid. Unmatched parenthesis.


(2) Providing a single, isolated line of code is not useful. Provide the actual script including any and all files the script requires to run.

(3) Please make sure your code is properly documented, i.e. comments should explain clearly and precisely what the given code is intended to do. This is especially important because there are multiple syntax issues even in the single line you posted. It's not self-evident what this code is supposed to do.

I asked you to provide the full script and all files it requires to run. I also asked you to explain what the faulty code is actually intended to do.

Code for a single <trial> element from the script is not responsive to either of these requests and does not enable me to tell you (a) what's wrong with your code and (b) how to fix it.

Please provide the information and materials I asked for. Thank you.

Thank you for your patience. I tried to avoid upload the whole script and any pictures it needs, since I don't know anything about the rights and permissions. Anyways, I fixed it by try end error, there were to many parantheses.
