Go No-go respond moving the mouse

Hi!

I creating a Go No-go task in which the participants see (Go stimuli) an arrow pointing left or right or (No-go stimuli) a blue arrow and have to respond by moving the mouse to the left or the right for a precise length from a starting point until it reaches a threshold (another physical point on the table where the mouse is): if they don't move the mouse far enough to reach the threshold it is not considered a correct_response but an "attempts".

I'm now using the mousetrap plugin.

The questions are:
1. How is it possible to consider as correct_response only the movement of the mouse that reaches the threshold?
2. Is it possible to measure the movements that do not reach the threshold? These are important for the purpose of the experiment because they are considered as "attempts". If a better way to measure them has already been found please tell!
3. If the participant does not move the mouse at all, it is a correct_response for the No-go stimulus, but an error if the Go stimulus is present.

Thank you for your help,

Tommaso
