When inferring the macro vascular component using oxford_asl, I assume the macro vascular timing parameters (dt_a and tau_a, arrival time and duration of the arterial bolus, referred in Chappell et al., MRM, 2010) are estimated in addition to aBV, since I got the following echo during the process:
Spatial VB (6 param: CBF, ^t, bCBF, b^t, tau, btau)
First, I would like to confirm that the prior values used for these parameters are those reported in Table 1, Chappell et al., MRM, 2010.
I would also like to save the dt_a and tau_a estimations and be able to change the values of the initial priors for these parameters. Is it possible with the actual version of the code?
Thanks in advance,
