Hi fsl Experts ,
I have acquired an Arterial Spin Labeling (ASL) series using a 3T philip scanner. I have problems defining the parameters for the model used on the analysis of the dataset. The dataset has 60 time points, 30 control and 30 labeled.
I have defined the perfusion option with control first, but I am not sure how to define the model. The acquisition has a TR of 4 s. I am not sure what info to place on teh full model setup for FEAT, any advise? Does the on/offf values should be TR/2 (2 s) and for phase (TR/2 = 2 s) ? what to use for convolution? (None)
Thanks
