Hello,
I have a question about the spatial priors set in oxford asl. As I understand it the priors are fixed values, for example the bolus arrival time is set at 0.7s for gray matter. Is it possible to set a range of priors, for example BAT 0.7-1.5s ,or, can I only run the analysis with a single value?
Perhaps oxford asl does some permutation testing in the background to determine the best fit to the data? Apologies if this has been answered before, but I would like to make sure my understanding of the priors is correct.
Regards,
Catherine
