Userloop "C" taskobject output format

Hi,

I'd like to write a userloop function that chooses my stimuli and passes it on to the timing script to be displayed using the ImageGraphic adapter.

However ImageGraphic input format is not the same as the "taskobject format" (e.g. 'pic(A.jpg,0,0,320,240,[0 0 0])') which appears to be the necessary format for outputting ("C") stimuli information from the userloop function.

Can I output out of the userloop function in any other format than the "taskobject format" indicated above?

I appear to be getting an error doing so, therefore I wanted to double check.

Thanks

See the TrialRecord.User part in the userloop manual.
