When a video that already has a barrier_opening row is loaded, a thin bar now appears below the player with a red vertical line at the marked opening_s. A tooltip shows the timestamp, the analyst's initials, and the bad_rois flag. Clicking the line snaps the player to the exact opening; clicking elsewhere on the bar seeks proportionally. Bar is hidden for un-annotated videos. API change: each queue item now carries an `existing` field with the opening_s, bad_rois, analyst, etc. from barrier_opening.csv when available, so the frontend can paint the mark without extra requests.

<h2>Welcome to the Cupido barrier picker</h2>
|
|
<p>For each tracked video you'll mark the moment the barrier between
|
|
the two halves of the arena is removed and the flies start interacting.
|
|
That timestamp is what every downstream "post-opening" analysis needs.</p>
|
|
|
|
<h3>How to annotate one video</h3>
|
|
<ol>
|
|
<li><strong>Drag the seekbar to the end of the video</strong> and check
|
|
whether <em>all</em> ROIs are open or only the upper or lower half.
|
|
This determines which button you'll click later.</li>
|
|
|
|
<li><strong>Drag back toward the beginning</strong> to roughly find
|
|
the moment the barrier(s) lift. The opening can be anywhere from a
|
|
few seconds to several minutes in.</li>
|
|
|
|
<li><strong>Use the arrow keys</strong> to pin down the exact frame:
|
|
<kbd>←</kbd>/<kbd>→</kbd> jump ±5 s, <kbd>Shift</kbd>+arrow jump ±30 s.
|
|
Pause the player on the opening frame.</li>
|
|
|
|
<li><strong>Click the button</strong> matching what opened — the
|
|
playhead time is recorded, ROI inclusion is set accordingly, and
|
|
the next video loads automatically.</li>
|
|
</ol>
|
|
|
|
<h3>The three buttons</h3>
|
|
<p>
|
|
<span class="button-tag">All barriers open</span> — every ROI usable<br>
|
|
<span class="button-tag">Upper barrier opens</span> — only ROIs 1, 3, 5 (top row); lower row will be excluded from analysis<br>
|
|
<span class="button-tag">Lower barrier opens</span> — only ROIs 2, 4, 6 (bottom row); upper row excluded
|
|
</p>
|
|
|
|
<h3>Other controls</h3>
|
|
<p>
|
|
<kbd>Space</kbd> play/pause ·
|
|
<kbd>1</kbd>/<kbd>2</kbd>/<kbd>3</kbd> the three buttons ·
|
|
<kbd>s</kbd> skip · <kbd>u</kbd> mark unusable
|
|
</p>
|
|
<p style="font-size: 0.85rem; color: #889;">Each click saves to
|
|
<code>barrier_opening.csv</code> immediately, so closing the tab
|
|
and coming back resumes from where you left off.</p>
