Hello.
Using the settings that you had mentioned, I made a basic example of how to obtain from MediaLab each person's 4 text responses, to later use in DirectRT.
In the file attached, "example.que" you will see the settings that I used, so that each text response per person is saved in its own column (importantly, not over-written!).
And, in the byquestionnaire and byvariablename folders created by MediaLab, you can extract each person's text responses, prepare for use in Direct RT. Of course you can choose which output to edit, CSV or TXT.
Attached is the text file from my example (from byquestionnaire), where each participant's text responses are side by side. Either copy/paste those to new text files (to us as input for DirectRT), or edit the MediaLab text file directly, then Save As a new text file, to be used as stimuli in DirectRT.
Please let me know if this is your goal or if meant something different.
