ANTsR (version 0.3.3)

antsrMotionCalculation: antsrMotionCalculation

Description

Correct time-series data for motion.

Usage

antsrMotionCalculation(img, fixed = NA, mask = NA, typeofTransform = "Rigid", verbose = FALSE)

Arguments

img

antsImage, usually ND where D=4.

fixed

Fixed image to register all timepoints to. If not provided, mean image is used.

mask

mask for image (ND-1). If not provided, estimated from data.

typeofTransform

One of "Affine", "Rigid", '"BOLDAffine", "BOLDRigid", "QuickRigid".

verbose

enables verbose output.

Value

List containing:

• moco_img Motion corrected time-series image.
• moco_params Data frame of translation parameters.
• moco_avg_img Average motion-corrected image.
• moco_mask Mask used to calculate framewise displacement.
• fd Time-series mean and max displacements.
• dvars DVARS, derivative of frame-wise intensity changes.

Examples

set.seed(120)
simimg<-makeImage(rep(5,4), rnorm(5^4))
antsrMotionCalculation( simimg )
