Apply the SCORE and SCRUB algorithms.
The Structural Correlation-based Outlier Rejection (SCORE) algorithm is applied to the CBF time series to discard CBF volumes with outlying values [1] before computing the mean CBF. The Structural Correlation with RobUst Bayesian (SCRUB) algorithm is then applied to the CBF maps using structural tissue probability maps to reweight the mean CBF [2].

- Mandatory Inputs:
asl_file (a pathlike object or string representing an existing file) – ASL file.
aslcontext (a pathlike object or string representing an existing file) – ASL context file.
prioritize_m0 (a boolean) – Whether to prioritize the M0 scan (useful for GE data) or not.
- Optional Inputs:
m0scan (a pathlike object or string representing an existing file) – M0 scan file. Only provided if M0Type is ‘separate’.
- Outputs:
selected_volumes_file (a pathlike object or string representing a file) – File containing the highest-contrast available volumes.
