A map plot shows objects across multiple imaging sessions. Objects persisting from one session to the next are connected with a line.

All map plots are interactive. Selecting an object will propagate this selection to other map and stack plots.

A large number of map plots can be generated using the plot panel.

There are two special plots provided in the main map manager panel: Spine Map and Segment Map.

Colors

The colors of objects in a map denote their dynamics.

  • Green : Added
  • Red : Subtracted
  • Blue : Transient (1 session)
  • Yellow : Persistent
  • White : Bad

Top control bar

Toggle the top control bar on and off with keyboard ‘c’.

  • Segment ID. Plot individual segments. Use ‘All Segments’ to plot all segment.
  • Bad. Toggle display of bad objects.
  • Stats. Display a table of statistics for plotted data.
  • Raw. Display a table of raw data.
  • Line fit.

Examples

All plots can be generated using the plot panel. There are two special plots provided in the main map manager panel: Spine Map and Segment Map.

This is an example of a ‘Spine Map’. It shows the position of each spine on its dendritic segment. The lines connect persistent spines across sessions. Added spines are in green, subtracted spines in red, and transient spines are in blue.

A map plot of spine length in μm (sLen2d) versus map session. The lines connect persistent spines across sessions. The colors are the same as the first example.

A map plot of spine length in μm (sLen2d) for session 1 versus session 0. Each point is the length of a single spine measured in session 0 (bottom axis) and again in session 1 (left axis).
