Questions on the Warning Messages
Greetings,
I’m new to VisionEgg and am hoping you could answer my questions on the warning messages that VisionEgg is giving every time I run my program. My program and a sample output/warning messages are attached. I have done some research online, but couldn't find a satisfying answer. Two different kinds of warnings appear every time I run the program: The first kind, “WARNING: Calculated frames per second was 60.763, while the VISIONEGG_MONITOR_REFRESH_HZ variable is 60.0.” The second kind, “WARNING: One or more frames took 34.0 msec, which is signficantly longer than the expected inter frame interval of 16.7 msec for your frame rate (60.0 Hz).” There are three go-loops in my program, and each go has had given me some warning messages during the test trials I ran. 1. What is it in my program that’s causing the warning messages? 2. Does it affect the accuracy of the display time and interval time between stimulus? Am I skipping a frame? 3. What can I change in my program to get rid of the warning messages?
Thank you so much!
