When partial volume correction (PVC) is used in PMOD, the saved tac files have ROIs with and without PVC. When loaded with load_tac()) it may be desirable to keep only either the PVC or non-PVC tacs. This returns a tac object that is a subset of the input tac object with only the PVC or non-PVC tacs. This relies on PMOD's convention of labelling tac columns with "_C".


split_pvc(tac, PVC = TRUE)



The time-activity curve data from loading function (PMOD)


If TRUE, includes columns with "_C", if FALSE, ones without "_C"


Time-activity curve object
