I'm trying to design an experiment using four clocks that all begin at different times and individually complete about one revolution per second. To do this I have twelve slides with four images per slide; each image is a clock, and each slide is the clock hand progressing to the next hour. When I run them sequentially the clock hand appears to be moving fairly smoothly. This gives me 48 attributes in my trial list, and when I tried to generate the script I received an error message telling me that there was too much information in trial level 0. If I remove two of the clocks (24 of the attributes) it runs without any problems. Would it let me run all four clocks if I preload the images instead of putting the .bmp into the trial list? Are there any other better ways to go about doing this? Any help would be much appreciated!

What is the exact text and number of the error message?

There should not be a limit to the number of attributes in a List (at least not that low).

If you are willing to attach a .es file or do so via web support we may be able to help.

The error message is:

A fatal error occurred while generating the DataSections code for the E-Object named 'TrialList'   Error Message: Data in Level 0 is too long for Embedded LoadMethod

While I have an idea of what this means, I'm not positive and am not sure of what to do to fix it. Thanks for looking at it.

This is a limitation to E-Prime 1.x that the total width of the characters in a row of a list cannot exceed 2048 characters.

Take a look at the attached.  Instead of the full path in each of the cells I placed [ClockStimuliFolder] attribute that if you set in the block list or via c.SetAttrib to a specific path, assigns the full path.  As of this edit, it is blank and assumes all of the images are in the same folder as the experiment *.es file for easy transportation.

I specified the path name in the Block List, and it's working perfectly. Thanks so much for your help!
