Running From MediaLab

QuickInfo

With MediaLab, you can easily embed a DirectRT session within your MediaLab experiment. Subject and Condition info will be consistent.

Details

You can run your input file from MediaLab. Simply select DirectRT Session as a questionnaire item and enter the input file in the File field. MediaLab will pass the current subject and condition Ids to DirectRT, launch the session, and then resume where it left off when the session has completed.

Note that DirectRT will still output its own data files that are separate from the MediaLab data files. You will be able to easily match them up though since DirectRT will use the subject and condition info from the current MediaLab Session.

Important: It is strongly advised that you don't run two DirectRT sessions from MediaLab back-to-back. DirectRT can fail to load if a previous instance of it has not yet had a chance to fully shut down. An easy fix for this is to insert a simple MediaLab instruction item between the DirectRT sessions (e.g., reading "Press the spacebar to continue").

Advanced Hint

If you only want to run a range of trials then use the c (command line argument) parameter followed by the range (e.g., c12-44), otherwise you can leave the parameters field as "none".
