OPTARI v0.8.6

New

• Motion widget: plots a spectral and a frame-to-frame motion score per frame, with a draggable frame line that is also in Time Analysis.
• Default frame: new options Motion (Spectral), Motion (frame-to-frame) and First ROI frame. Spectral falls back to frame-to-frame for single-wavelength scans.
• ROI presets: a “Location” dropdown from the segmentation classes and an editable top margin. Placed ROIs carry their location into exports.
• Batch mode: improved controls, validation by button, faster scan loading while validating, and a new preset for measuring a scan’s own ROIs.
• Exported metadata now includes the processing settings.
• Docs: workflow demo videos, an install FAQ for a missing Ubuntu system library, and fixed links.

Fixes

• Double-clicking a preset no longer resets the placement you chose.
• ROI from Mask keeps its class list when the model or preset changes.
• Generated ROIs have the exact size and margin you entered.
• Frame and spatial alignment in the export/import roundtrip.
• Misalignment from PATATO’s resolution reduction in unmixing.

Note

The config schema version was updated to 6: This means on first start, your ~/.optari/config folder (settings, the segmentation model list and all presets) is moved to ~/.optari/config_old_ and replaced with new defaults. Downloaded models, logs and autosaves are not affected.

OPTARI v0.8.4

• Demo scans: updated
• Frame selection: The starting frame can now be the iThera acquisition start frame.
• ROI: The mask is no longer rounded before it is rasterized, so ROI masks are more accurate.
• Windows: Reverted to OS native file dialog is back
• Dependencies: The PATATO wheels are updated. Supports iROI files and acquisition start frame
