cifti.file.looks.like.cifti1: Check whether a file looks like a CIFTI-1 file.

In freesurferformats: Read and Write 'FreeSurfer' Neuroimaging File Formats

Check whether a file looks like a CIFTI-1 file.

Description

This is a heuristic used to produce a helpful error message when a CIFTI-1 file is passed to the reader: CIFTI-1 files are NIFTI-1 files (not NIFTI-2), and this function searches the first bytes of the file for the string 'CIFTI'. It is not used for any other purpose.

Usage

cifti.file.looks.like.cifti1(filepath)

Arguments

filepath

character string, the path to a CIFTI-2 file (usually one of .dscalar.nii, .dtseries.nii, .dlabel.nii, .dconn.nii, .pscalar.nii, .ptseries.nii, .pconn.nii, .dpconn.nii or .pdconn.nii). Note that this is not a NIFTI file, despite the .nii part. Gzipped CIFTI files are not supported, because the CIFTI-2 format forbids compression.

Value

logical, whether the file looks like a CIFTI-1 file.
