Problem with Inquisit 4.0.4 and MediaLab V2012.4.131

By densonlab - 2/26/2014

Hi there,

I am using Medialab 2012.4.131 and when trying to pull up and Inquisit 4.0.4 script the program is requesting participant ID and condition details, which it used to get automatically from the medialab file (older version of medialab). Does anyone know how I might get around this so participants are not shown this screen and the information is generated automatically again?

Any help would be greatly appreciated.

That's something you would have to ask the MediLab / Empirisoft support staff, I think. I don't know how MediaLab passes (or used to pass) those parameters to an Inquisit session. Note though that the command line syntax for invoking Inquisit 4 changed compared to Inquisit 3. You will find this covered in the "How to Launch Inquisit Using Command Line Parameters" topic in the Inquisit documentation.

Hi Dave,

Thanks for your reply! I'll see what I can find on the Empirisoft forums.

Hey guys! Was googling around for an answer to this very question and found my way here! 

I found this link:

And consistent with what's mentioned here, it looks like the way subject IDs are passed to Inquisit has changed. MediaLab has always passed the subject ID to Inquisit WITHOUT the -s. It seems Inquisit expects that now and so the old way no longer works. I'm tempted of course to change the code in MediaLab to accommodate this, but I don't want to BREAK compatibility for users still running Inquisit 3 and prior. What happens, e.g., if an Inquisit 3 user has MediaLab send the "-s 1000" command line parameters--will it just ignore the "-s", or will it break? Hmmm. Alternatively, is there any way to have Inquisit -assume- the old subject ID is being passed if only a single number appears as a command line option (e.g., so "1000" without the -s would still work)?

Hi all.  Blair and I believe that we found a solution using command line logic and the executable item type in MediaLab .que files.  For more details, please see the information at the following link to the Empirisoft forum:
