vis.dti.trk: Visualize DTI tracks from Diffusion Toolkit/TrackVis TRK format file.

Description

Visualize DTI tracks from Diffusion Toolkit/TrackVis TRK format file.

Usage

vis.dti.trk(
  trk,
  filter_tracks = list(min_length = 15, min_segment_count = 6),
  color_by_orientation = FALSE
)

Value

The (loaded or received) trk instance. Note that this function is typically called for the side effect of visualization.

Arguments

trk

character string, the path to a TRK file that should be loaded. Alternatively, a loaded trk instance as returned by freesurferformats::read.dti.trk.

filter_tracks

optional, named list of filters. Can contain fields min_length and min_segment_count. Set the whole thing to NULL or an entry to 0 for no filtering.

color_by_orientation

logical, whether to color the tracks by orientation. Slower, but may make the resulting visualization easier to interprete.

Examples

if (FALSE) {
# Create the following file with Diffusion Toolkit from your DTI data:
trk = freesurferformats::read.dti.trk("~/data/tim_only/tim/DICOM/dti.trk");
vis.dti.trk(trk);
}
