.find.bval.file

Looks for the <code>bvals</code> file next to a <code>bvecs</code> file, by replacing
the <code>bvec</code>/<code>bvecs</code> part of the file name with <code>bval</code>/<code>bvals</code>, 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
<code>sub-01_dwi.bvec</code> and <code>sub-01_dwi.bval</code>.

Provides functions to read and write neuroimaging data in various file formats, with a focus on 'FreeSurfer' formats. This includes, but is not limited to, the following file formats: 1) MGH/MGZ/NIFTI format files, which can contain multi-dimensional images or other data. Typically they contain time-series of three-dimensional brain scans acquired by magnetic resonance imaging (MRI). They can also contain vertex-wise measures of surface morphometry data. The MGH format is named after the Massachusetts General Hospital, and the MGZ format is a compressed version of the same format. 2) 'FreeSurfer' morphometry data files in binary 'curv' format. These contain vertex-wise surface measures, i.e., one scalar value for each vertex of a brain surface mesh. These are typically values like the cortical thickness or brain surface area at each vertex. 3) Annotation file format. This contains a brain surface parcellation derived from a cortical atlas. 4) Surface file format. Contains a brain surface mesh, given by a list of vertices and a list of faces.
