Hello,
We are trying to launch a new study mirroring our previous one. In the past study, subject id was generated by the url parameter "subjectnumber", although this didn't actually refer to subject number. We used it in our batch script below to specify which task participants would do first.
<batch>
/subjects = (1 of 4)
/groupassignment = subjectnumber
/file = "child-attribution-GNAT.iqx"
</batch>
<batch>
/subjects = (2 of 4)
/groupassignment = subjectnumber
/file = "child-APP.iqx"
</batch>
<batch>
/subjects = (3 of 4)
/groupassignment = subjectnumber
/file = "high_load.iqx"
</batch>
<batch>
/subjects = (4 of 4)
/groupassignment = subjectnumber
/file = "low_load.iqx"
</batch>
Group ID was then generated by the url parameter "groupnumber", meaning what version of the task they would do:
For instance:
<expt>
/groupassignment = groupnumber
/subjects = (1 of 4)
/blocks = [1= preinstruction; 2=scenarios_practice; 3= trialinstruction;
4= scenarios_positive01; 5= scenarios_negative01; 6= scenarios_positive02; 7=scenarios_negative02; 8= finish]
</expt>
Everything worked fine! Now, as we are trying to start the second study we are running into troubles with groupnumber. Links for the first task (below) work.
This link
http://research.millisecond.com/ubcparentinglab/Newstudy.web?subjectnumber=1&groupnumber=2 works.
But links for the second and third tasks (subjectnumber):
http://research.millisecond.com/ubcparentinglab/Newstudy.web?subjectnumber=2&groupnumber=2 and
http://research.millisecond.com/ubcparentinglab/Newstudy.web?subjectnumber=3&groupnumber=2don't.
We get this error message: "Could not load file
http://www.millisecond.com/myaccount/scripts/ubcparentinglab/Newstudy/high-load.iqx. HTTP status code 404"
It seems like our new batch script is working because the error message identifies the correct subjectnumber (high-load), but that the group number is not.
Any thoughts?
Thanks!
