slicetiming: slicetiming for fmridata-objects

In WIAS-BERLIN/fmri: Analysis of fMRI Experiments

slicetiming for fmridata-objects

Description

Perform slicetiming for fMRI data, ideally before preprocessing (registration). Recording times for slices are assumed to be equispaced between scans with argument sliceorder providing the order of slice acquisitions. Interpolation between slices is performed using a sinc filter.

Usage

slicetiming(fmridataobj, sliceorder = NULL)

Arguments

fmridataobj	object of class fmridata
sliceorder	order of lice acquisitions

Value

an object of class fmridata

Examples

  ## Not run: 
# Example 1
  data <- list(ttt=writeBin(rnorm(32*32*32*107), raw(), 4),
               mask=array(TRUE, c(32, 32, 32)), dim=c(32, 32, 32, 107))
  class(data) <- "fmridata"
  data <- slicetiming(data,sliceorder=1:32)
  ## provides data corrected for sequential slice acquisition in linear order

## End(Not run)
