mne_videobrowser.browsers.RawBrowserManager

class mne_videobrowser.browsers.RawBrowserManager(raw_browser: RawBrowserInterface, raw: Raw, selector_padding=0.1, default_selector_position=0.5, parent: QObject | None = None)

Bases: SyncableBrowserObject

Manager for raw browser instance tailored for time syncing with video.

Provides methods for manipulating the view and adds a ‘time selector’ (vertical line) that marks the time point used for syncing with video. Emits signal when the selected time is changed.

Parameters:

• raw_browser (RawBrowserInterface) – The raw browser to manage wrapped in RawBrowserInterface.

• raw (mne.io.Raw) – The raw data object being displayed in the browser.

• selector_padding (float, optional) – Padding (in seconds) to apply when clamping the time selector to the current view range of the raw data browser, by default 0.1

• default_selector_position (float, optional) – The default relative position of the time selector in the raw data browser’s view, given as a fraction between 0 and 1, by default 0.5

• parent (QObject, optional) – The parent QObject for this manager, by default None
