MRIaggr-class: Class "MRIaggr"

Description

Patient-specific storage of multivariate contrast data and clinical data.

Arguments

hemispheres
the presence or absence of lesion(s) in each hemisphere. data.frame.
midplane
the position of the mid-sagittal plane. data.frame.
W

table_reperfusion
the volumic reperfusion data. data.frame.
table_hypoperfusion
the volumic hypoperfusion data. data.frame.
ls_statDesc
a slot to store additional data. list.
