In TKoscik/tk.nifti: Read and Write NIfTI Files

Description

Write Dataframe or Matrix to NII file

Usage

  table.to.nii(in.table,
               coords,
               save.dir,
               prefix=NULL,
               do.log=TRUE,
               model.string=NULL,
               ref.nii=NULL,
               img.dims=NULL,
               pixdim=NULL,
               orient=NULL)

Arguments

in.table	dataframe or matrix object to output to NII file
coords	voxel coordinates of location in NII file to write values
save.dir	directory location to save output
prefix	prefix to be the base of filenames, default is the name of the input table object
do.log	logical, whether or not to write log file providing details about what the output contents are. this may be helpful for sorting through volumes.
model.string	A string to wirte to the log file specifying describing or specifying the model that was run
ref.nii	a reference NII image to draw image properties from (e.g., dimensions and orientation)
img.dims	voxel dimensions of target NII file
pixdim	voxel dimensions of NII output
orient	orientation list object of NII output

Value

Output directly to log.text file and write to specified coordinates in a set of NII files.
