MultiSubjectParcellation

class nipy.labs.spatial_models.parcellation.MultiSubjectParcellation(domain, template_labels=None, individual_labels=None, nb_parcel=None)

Bases: object

MultiSubjectParcellation class are used to represent parcels that can have different spatial different contours in a given group of subject It consists of self.domain: the specification of a domain self.template_labels the specification of a template parcellation self.individual_labels the specification of individual parcellations

fixme:should inherit from mroi.MultiROI

__init__(domain, template_labels=None, individual_labels=None, nb_parcel=None)

Initialize multi-subject parcellation

Parameters :

domain: discrete_domain.DiscreteDomain instance, :

definition of the space considered in the parcellation

template_labels: array of shape domain.size, optional :

definition of the template labelling

individual_labels: array of shape (domain.size, nb_subjects), optional, :

the individual parcellations corresponding to the template

nb_parcel: int, optional, :

number of parcels in the model can be inferred as template_labels.max()+1, or 1 by default cannot be smaller than template_labels.max()+1

check()

Performs an elementary check on self

copy()

Returns a copy of self

get_feature(fid)

Get feature defined by fid

Parameters :fid: string, the feature identifier :

make_feature(fid, data)

Compute parcel-level averages of data

Parameters :

fid: string, the feature identifier :

data: array of shape (self.domain.size, self.nb_subj, dim) or :

(self.domain.sire, self.nb_subj) Some information at the voxel level

Returns :

pfeature: array of shape(self.nb_parcel, self.nbsubj, dim) :

the computed feature data

population()

Returns the counting of labels per voxel per subject

Returns :population: array of shape (self.nb_parcel, self.nb_subj) :

set_feature(fid, data)

Set feature defined by fid and data into self

Parameters :

fid: string :

the feature identifier

data: array of shape (self.nb_parcel, self.nb_subj, dim) or :

(self.nb_parcel, self.nb_subj)

the data to be set as parcel- and subject-level information

set_individual_labels(individual_labels)

set_template_labels(template_labels)
