Hi, I just start to use simulink. Now I have 8 positions where I want my targets to be displayed. So basically, the process will be something like target1 shows in posotion1 and subject’s hand reaches the target1 before target1 disappear, then target2 shows in position2… so can anyone explain how can I define the x,y position of my targets and how can I randomize the sequence of those targets?
The simplest way to do this would be to have a column in the Trial Protocol (TP) table that refers to the Target table and for different trials you would use different targets. In the Target table you would define your targets and their locations. Then in the Block table you would randomize the order of trials.
I’d like to recommend you look at our sample reaching task https://kinarm.com/download/reaching-sample/ and see if that can help you.
