R Documentation

Convert Between fmridata and oro.nifti Objects

Description

NIfTI data can be converted between fmridata S3 objects (from the fmri package) and nifti S4 objects.

Usage

oro2fmri(from, value = NULL, level = 0.75, mask=NULL, setmask = TRUE)
fmri2oro(from, value = NULL, verbose = FALSE, reorient = FALSE,
         call = NULL)

Arguments

`from`	is the object to be converted.
`value`	`NULL`
`level`	is the quantile level defining the mask.
`mask`	array or nifti-object containing the mask. If set this replaces the mask defined by argument level.
`setmask`	is a logical variable (default = `TRUE`), whether to define a suitable mask based on `level`.
`verbose`	is a logical variable (default = `FALSE`) that allows text-based feedback during execution of the function.
`reorient`	is a logical variable (default = `TRUE`) that enforces Qform/Sform transformations.
`call`	keeps track of the current function call for use in the NIfTI extension.

Details

These functions enhance the capabilities of fmri by allowing the exchange of data objects between nifti and fmridata classes.

Value

The function oro2fmri produces an S3 object of class fmridata. The function fmri2oro produces an S4 object of class nifti.
