Re: [Freesurfer] Optseq2 - Repeating Stimuli and Contrasting the Repetitions

Hi Ruth, there are no ways to constrain the order of the stimuli in this way in optseq. If the timing is fixed between these 3 items, then they are effectively one stimulus type, and you can optimize the order of that one stimulus type. On 11/10/2016 01:31 PM, Ruthie Shaffer wrote: > Hi all, >

[Freesurfer] Optseq2 - Repeating Stimuli and Contrasting the Repetitions

2016-11-10 Thread Ruthie Shaffer
Hi all, I’m posting to ask for advice on setting up certain parameters in optseq2: Specifically, in optseq2, how can one set up parameters to best optimize a task where there are say 20 items presented 3 times, where the relevant contrasts are between the first, second, and third presentations
