Description

To read tm functionnal images 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.

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.
