Hi Shimrit,
The only difference would be in your StimList. Instead of typing ~ followed by a word you want to used for a stimulus, you list the filenames of the images in the Stim folder and/or the file pathway of any images that are located in a different folder. So if you had a .bmp in the Stim folder named horse, you would simple type horse in the StimFile to tell DirectRT to find the picture .bmp file named horse. You would use $ folled by the name of the StimFile in your input file. You can also refer to the Input Files > Stim section of the DirectRT manual for this information.
