threeDto4D: threeDto4D

In AnalyzeFMRI: Functions for Analysis of fMRI Datasets Stored in the ANALYZE or NIFTI Format

Description

To read tm functionnal images files in ANALYZE or NIFTI format, and concatenate them to obtain one 4D image file in Analyze (hdr/img pair) or Nifti format (hdr/img pair or single nii) which is written on disk. Note that this function outputs the files in the format sent in. If desired, one can use the function analyze2nifti to create NIFTI files from ANALYZE files.

Usage

threeDto4D(outputfile,path.in=NULL,prefix=NULL,regexp=NULL,times=NULL,
       list.of.in.files=NULL,path.out=NULL,is.nii.pair=FALSE,hdr.number=1)

Arguments

outputfile	character. Name of the outputfile without extension
path.in	character with the path to the directory containing the image files
prefix	character. common prefix to each file
regexp	character. Regular expression to get all the files
times	vector. numbers of the image files to retrieve
list.of.in.files	names of img files to concatenate (with full path)
path.out	where to write the output hdr/img pair files. Will be taken as path.in if not provided.
is.nii.pair	logical. Should we write a signle nii NIFTI file or a hdr/img NIFTI pair file
hdr.number	Number of the original 3D Analyze or NIFTI image file from which to take the header that should serve as the final header of the newly 4D created image file

Value

None.
