Gray screen between trials

Hi everyone,

I used the Builder to create a loop of trials. I defined the parameters of the trials using an Excel file with rows as trials and columns as parameters. When I run the paradigm, there is a gray screen between the trials (each trial includes a few pictures). I want to eliminate that gray screen. I checked the timing on the Excel file and there is no gap in the timing between the trials.

I’d appreciate suggestions on eliminating the gray screen between trials.

Thank you!

How big are the pictures? It could be a loading delay.

Each image is around 360 KB. I’m not sure if this is the issue because we used the same pictures in a different paradigm and it works. I noticed that the gray screen timing is not fixed. I’m attaching a screenshot of the Excel file, maybe it includes an issue that I’m not aware of.

Thank you so much!

Hi again,

I rethought your suggestion and I think you’re right - it might be a loading delay because in the CSV data file, I see a gap between the start of the trial and the actual time when the first picture is presented.

If this is the case, I’m wondering how to deal with this loading delay. Please let me know if you have any ideas.

Many thanks,

Hello

You could try to reduce the delay by not starting the image presentation at the start of the trial, if you are not already doing this.
