Configuration

Most OPTARI settings can be changed from inside the app. Open OPTARI → Settings… in the menu bar. Any dock can be shown or hidden from OPTARI → Docks.

Tab	Available Settings
General	Operator name, log verbosity, histogram bin count
Viewer	Default layer/frame/channel selected when a scan loads, playback speed, fallback pixel scale, layer colormaps
Docks	Which panels are visible when OPTARI starts
ROI Table	Which columns the Live Analysis table shows, the ROI color palette
Models	The segmentation model registry and the default model (read-only)
Paths	Where your config, presets, models, and log file are stored (read-only)

Note

Settings are read once at startup, so changes take effect after you restart OPTARI.

Reconstruction, unmixing, ROI, and segmentation presets are not edited here. Each has its own Save Preset / Remove Preset controls in its own dock. See Presets.

Editing settings from file

OPTARI's settings and presets are stored in the ~/.optari/ folder as human-readable JSON. This folder is created on first launch and filled with defaults. The full reference can be found in Configuration Schema. The same restart-required rule applies.
