Erase shape after set duration

Hi,

How to erase a shape after a set duration ? without using a blank rectangle.

I have a rectanglular shape with text in the centre. I want subjects to respond before the rectangle disappears. If I use blank rectangle, even text is overwritten. I just want the shape to get erased after lets say 600 ms and text to remain on the screen.

Please advise.

Thanks

Abhi

You need to overwrite the shape using another one and re-draw the text at the appropriate point in time:

<trial mytrlal>
/ stimulustimes = [0=myshape; mytext; 600=eraseshape; mytext]
[...]
</trial>

Thanks Dave

I was using stimulusframes. Will shift to stimulustimes now.

Thanks
