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
)

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.

Value

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

Examples

# NOT RUN {
# 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);
# }
# NOT RUN {
# }
