User interface

The image and navigation controls are on the left; the temporal plot, ROI table, and event controls are on the right.

The image panel displays the selected frame. Clicking a pixel moves the crosshair and updates the black temporal trace. The plot also shows colored traces for visible ROIs. The table below it controls ROI visibility, selection, names, colors, geometry, and current-frame measurements. Event controls become available when the Save Folder contains usable events.mat information.

Menus

The Management menu separates routine folder, project, and rig association from File operations.

Control	Available when	Effect and persistence
File > Open	Always	Opens .dat or image-kind .umt; read-only.
File > Save	Data is loaded	Saves the current data under a chosen supported name.
File > Import > from bin/from tif	Always	Creates processed data and metadata in a Save Folder.
File > Export > to tif	Compatible image data is loaded	Writes TIFF output; the source remains unchanged.
Management > Set Raw Folder	Data and an accessible Save Folder	Stores a selected path, the Save Folder itself, or Missing in DataParams.mat.
Management > Project > Bind Current Session	Data and an accessible Save Folder	Opens Project Binding Manager with the current Save Folder, without duplicating project, subject, and session choices in DataViewer.
Management > Project > Project Manager	Always	Opens the full project-administration interface.
Management > Rig > Assign Rig	Data is loaded	Lists readable Active or Available rigs. The current rig is checked; replacing it requires confirmation.
Management > Rig > Rig Manager	Always	Opens the full rig-administration interface.
Help > Online documentation	Always	Opens the documentation site.

Tabs

Tab	Control	Use
Utilities	View Calibration	Set pixel scale and coordinate origin. See Image calibration.
	Logical Mask	Draw, automatically create, preview, confirm, or reset the analysis mask.
