Hi I need some help. I'm confused by these parameters. I have learned the manual. In the manual, different jobs have different parameters. I don't know how to changes these parameters to get a best result. Can you tell me how to set them? Thanks a lot 360截图20210612130928834

microtime resolution: if you want to estimate HRF with the finer temporal resolution, set it >1 Threshold for event detection: it's the threshold for point process detection, I always do not change it. K: we assume the amplitude of 'event' is always the 'local' maximum value (here is the information about how to define the local maximum) temporal mask for event detection: you can add it when you want to delete some spurious events (such as time points with high head motion)

Thanks a lot for your reply. And I also want to ask that how to set the "Microtime oneset"? Is there any relationship between "Microtime oneset" and “Microtime resolution”? Thanks

guorongwu commented 3 years ago

when you increase the temporal resolution (if Microtime resolution is k), each time point will become k time points, e.g. one of the first k time points should be selected as the (original) first time point, that's 'Microtime onset'. you can just set it as 1 if you do not know which is the best.

OK, I get it. Thank you very much.
