Access Templateflow Brain Templates

Description

Retrieves standardized neuroimaging templates from the Templateflow repository. Provides access to various brain templates, masks, segmentations, and atlases in standardized spaces.

Usage

get_template(
  name = "MNI152NLin2009cAsym",
  desc = "brain",
  resolution = 1,
  label = NULL,
  atlas = NULL,
  suffix = "T1w",
  extension = ".nii.gz"
)

Arguments

name	Character string specifying template name. Default: "MNI152NLin2009cAsym"
desc	Character string describing template variant. Default: "brain"
resolution	Numeric resolution in mm. Default: 1
label	Character string specifying tissue label for probability maps
atlas	Character string specifying atlas name
suffix	Character string specifying image type. Default: "T1w"
extension	Character string specifying file extension. Default: ".nii.gz"

Details

The function provides access to various template resources:

Template Spaces Available:

• MNI152NLin2009cAsym: Non-linear asymmetric MNI template (default)

• MNI152NLin6Asym: Older non-linear MNI template

• OASIS30ANTs: Template derived from OASIS dataset

• NKI: Nathan Kline Institute template

• WHS: Waxholm space rat template

Common Descriptors (desc):

• brain: Brain-extracted template

• head: Full head template

• mask: Binary brain mask

• dseg: Discrete segmentation

• probseg: Probability maps

Labels for Segmentations:

• GM: Gray matter

• WM: White matter

• CSF: Cerebrospinal fluid

Value

A NeuroVol object containing the requested template
