dot-find.bval.file: Find the b-value file that belongs to a b-vector file.

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

Find the b-value file that belongs to a b-vector file.

Description

Looks for the bvals file next to a bvecs file, by replacing the bvec/bvecs part of the file name with bval/bvals, and by replacing the file extension if that does not match. This makes the readers work out of the box on standard datasets, e.g. the BIDS files ⁠sub-01_dwi.bvec⁠ and ⁠sub-01_dwi.bval⁠.

Usage

.find.bval.file(bvec_filepath)

Arguments

bvec_filepath

character string, path to the b-vector file.

Value

character string, the path to the existing b-value file, or NULL if none of the candidates exists.
