[–clusters_lt int] [–native_coords] [–stealth] [–emergency_header str] [–bg_color [float …]] [–disable_order_transparency] [–buan] [–buan_thr float] [–buan_highlight [float …]] [–roi_images] [–roi_colors [float …]] [–out_dir str] [–out_stealth_png str] input_files [input_files …]

Interactive medical visualization - Invert the Horizon!

Interact with any number of .trk, .tck or .dpy tractograms and anatomy files .nii or .nii.gz. Cluster streamlines on loading.

Positional Arguments

input_files

Optional Arguments

-h, --help

show this help message and exit

--cluster

Enable QuickBundlesX clustering.

--cluster_thr float

Distance threshold used for clustering. Default value 15.0 for small animal brains you may need to use something smaller such as 2.0. The distance is in mm. For this parameter to be active cluster should be enabled.

–random_colors [str …]

Given multiple tractograms and/or ROIs then each tractogram and/or ROI will be shown with different color. If no value is provided, both the tractograms and the ROIs will have a different random color generated from a distinguishable colormap. If the effect should only be applied to one of the 2 types, then use the options ‘tracts’ and ‘rois’ for the tractograms and the ROIs respectively.

--length_gt float

Clusters with average length greater than length_gt amount in mm will be shown.

--length_lt float

Clusters with average length less than length_lt amount in mm will be shown.

--clusters_gt int

Clusters with size greater than clusters_gt will be shown.

--clusters_lt int

Clusters with size less than clusters_gt will be shown.

--native_coords

Show results in native coordinates.

--stealth

Do not use interactive mode just save figure.

--emergency_header str

If no anatomy reference is provided an emergency header is provided. Current options ‘icbm_2009a’ and ‘icbm_2009c’.

–bg_color [float …]

Define the background color of the scene. Colors can be defined with 1 or 3 values and should be between [0-1].

--disable_order_transparency

Use depth peeling to sort transparent objects. If True also enables anti-aliasing.

--buan

Enables BUAN framework visualization.

--buan_thr float

Uses the threshold value to highlight segments on the bundle which have pvalues less than this threshold.

–buan_highlight [float …]

Define the bundle highlight area color. Colors can be defined with 1 or 3 values and should be between [0-1]. For example, a value of (1, 0, 0) would mean the red color.

--roi_images

Displays binary images as contours.

–roi_colors [float …]

Define the color for the roi images. Colors can be defined with 1 or 3 values and should be between [0-1]. For example, a value of (1, 0, 0) would mean the red color.

Output Arguments(Optional)

--out_dir str

Output directory. (default current directory)

--out_stealth_png str

Filename of saved picture.
