RDK plugin: calculating coherence and checking signal and noise dots on each frame

[hariPurohit]

hey
@vrsivananda

I was curious to know how are the coherences calculated for the rdk plugin? I am hoping to design my RDM experiment on jspsych and want to be as precise in the details regarding the dot coherence, RDM algorithm used, etc. just like how RDM tasks are defined in papers by Shadlen, Ratcliff and others.

Is there a way to check the number of signal and noise dots on each frame while running the task on a browser and then storing these variables as an array?

For e.g., if i have 5 dots and 3 sets of dot sets, with three coherence levels (0.10, 0.15 & 0.20), is there a way to track the positions of the dots?
