[DMDX] RE: DMDX question Hi Irina.   Heres a bit of code I'm working on at the mo which presents two bitmaps simultaneously (with one overlapping the other). +1 *    "y",    "black",    "black" ; My screens set to 800x600 for the above code, and my pics are 400x400. Check out the DMDX helpfile for the "XY Keyword" for more info. The "XY Justification Keyword" might be useful too. Mike has a good tutorial on pic presentation on his site: http://www.mrc-cbu.cam.ac.uk/Language/DMDX/paradigms/parad7.html . Please note that the negative Y co-ordinate for one of the bmp's up here actually places part of that pic off screen.  If you have a lot of different pictures which need to be randomly placed into the 4 corners of the screen (in random combinations of all the pictures), your best bet it to use excel to create your rtf files. There might be a cunning way to get dmdx to do that sort of thing to, but I'm stuck for ideas.  Andy.  -----Original Message----- From: DMDX-owner@psy1.psych.arizona.edu [mailto:DMDX-owner@psy1.psych.arizona.edu] On Behalf Of Irina a. Sekerina Sent: 14 February 2004 02:10 To: DMDX@psy1.psych.arizona.edu Subject: [DMDX] DMDX question Mike, I wonder if you could give me advice on a particular DMDX design issue I am trying to implement. In an remote eye-tracking experiment, I am going to present my subjects  with 4 different pictures while they listen to spoken sentences  describing one of them. Their task is to choose the picture by naming  its number. Is it possible to write a DMDX script in such a way that  these 4 pictures are separate .jpg files but appear simultaneously on  the screen, each in its quarter of the screen, in a scrambled order? I can not figure it out myself, and the alternative is to create a  picture consisting of 4. Then scrambling of the 4 pictures will require  creating 4 versions of the composite picture, and it is a lot of work.
