get.dti.trk.endianness

internal

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.

get.dti.trk.endianness function

<dl><dt>filepath</dt>
<dd>character string, path to file in trk format. Gzip-compressed
files are supported as well (the compression is detected from the file
content, so a <code>.trk.gz</code> file is read like any other TRK file), which is
convenient since tractograms are large and are regularly stored compressed.
Note that track files cannot be compressed on the fly for other software:
the TrackVis tools and MRtrix do not read compressed track files.</dd></dl>
