Convert Between fmridata and oro.nifti Objects

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

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.
