slicetiming function

slicetiming for fmridata-objects

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.

slicetiming(fmridataobj, sliceorder = NULL)

Arguments

• fmridataobj: object of class fmridata
• sliceorder: order of lice acquisitions

Returns

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)
