Edit Vessels Panel (3D)

Learn about the editing functionalities:

Select all the vessels traced. Alternatively you can select one or several vessels with the mouse:

  • To select a single vessel, click the vessel.
  • To select several adjacent vessels, press the CTRL key and draw a marquee (rectangle) around the vessels of interest.

When Points is selected, vessels are displayed as a series of points that you can edit.

  • To select a point, click it.
  • To select multiple adjacent points, hold down Ctrl and draw a marquee (rectangle) around the points of interest.
  • To move a point, drag it.
  • To delete a point, click it then press the Delete key.

When Detach is selected, you can detach/split segments.

  1. Click a vessel to select it.
  2. Click the Detach button.
  3. Click on the vessel to detach.
    • If you click a segment, the program splits the segment into two.
    • If you click a bifurcation/node, the program splits the vessel into three vessels.

     

When Connect is selected, the vessels are represented as series of points and you can connect/splice segments.

  1. Click and drag an end point toward the area you want to connect to. The end point briefly turns green and a green line appears.
  2. Release the mouse button to connect the segments.

After tracing complex structures with the user-guided or automatic tracing mode, there may be fragments. This function automatically identifies these issues and lets you resolve them quickly.

  • no branch points: The vessel doesn't include any node or branch point -- Fix Edit manually.
  • Vessel fragment found: The vessel has two or less points -- Fix will delete the vessel automatically.
  • ending not at image boundary: The ending point is not at the image boundary -- Fix Edit manually.

Indicates that the fragment can be deleted automatically.

Indicates that manual editing is recommended (e.g., merging).

 

  • To delete all the fragments marked by in the list, use the Clean All button.
  • To inspect a specific issue, click the issue; you'll be redirected to the corresponding area in the tracing.
  • To resolve a specific issue, click in the Fix column.

Use classify to categorize segments for later analysis in Vesselucida Explorer.

  1. Click to select a segment; a selected segment is indicated by three white squares (beginning, middle, and end of segment).
  2. Select a name from the drop-down menu. To customize the names in the list, click the Color sets button, highlight a name and type a new name.

Use to visualize flow direction for all traced vessels at the segment level. Red indicates the beginning of segment, blue indicated the end.

Change direction

Direction can be changed for individual segments, but not for entire vessels.

You can only change the direction of a segment that has one open endpoint and is connected to another segment.

To reverse the direction of a segment, click a segment to select it, then click the button. When a segment is selected, you can see three squares (beginning, middle and end of segment). As a result, the segment is recolored and the beginning point is now red.

Set origin

You have the option to define origins for segments that have one open end and are connected to other segments. Click a segment to select it then click the Set origin button. This will update the flow direction and set the origin to the open endpoint.

Clear origin

Use to undo SET origin.

When you use this option, the direction of the flow is NOT automatically reverted. Use the Change flow direction button.

Removes all selected vessels.
