As 2018 is coming to a close it's a good time to reflect on the things that went right and those things that didn't quite go to plan. As the title of this blog post suggests, some of the unique quirks of the program we use to generate and display our visual stimuli, FlyFly, lead to one set of my stimuli being displayed at a location I was not expecting. My lesson to take into 2019 is to check and recheck my stimulus settings. A quick visual check of the display on screen is not necessarily enough especially with the complexity of many of the stimuli we are currently using.
In the example shown below, the stimulus is a small circular target displayed on a 3d optic flow also consisting of circles, which makes it quite difficult to ascertain if the target is in the expected starting location by simply watching the display on the screen. To confirm the correct parameters are being displayed, using a grid representation of my screen, I have marked the starting location and direction of the target with an arrow. This arrow is then overlaid onto a video generated from my stimulus settings to confirm the correct location of the stimuli is being generated and displayed.
