write.smp.brainvoyager

Write a brainvoyager SMP file, which contains one or more vertex-wise data maps (stats or morphometry data).

Provides functions to read and write neuroimaging data in various file formats, with a focus on 'FreeSurfer' <http://freesurfer.net/> formats. This includes, but is not limited to, the following file formats: 1) MGH/MGZ 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.

<dl><dt>filepath</dt>
<dd>character string, the output file</dd>
<dt>bvsmp</dt>
<dd>bvsmp instance, a named list as returned by <code>read.smp.brainvoyager</code>.</dd>
<dt>smp_version</dt>
<dd>integer, the SMP file format version to use when writing. Versions 2 to 5 are supported, but only versions 2 and 3 have been tested properly. Please report any problems you encounter. When converting between file versions (e.g., loading a v2 file and saving the result as a v5 file), some required fields may be missing, and for those without a default value according to the official spec, you will have to manually add the value you want in the bvsmp object before writing.</dd></dl>
