About
Trajectory from trial start to the end of the recording, colored by 8 equal bands of elapsed time (viridis - perceptually uniform, colorblind-safe, and survives greyscale printing; banded rather than a smooth blend so neighboring time periods stay visually distinct). The bands are a fixed, even split of time, not a detected behavioral phase - a color change marks a clock boundary, not an event. Click a point to seek the video there. Failed-tracking frames break the line rather than bridging it - a gap is never silently interpolated.

About
Occupancy over the platform, trial start to end of recording - how much time was spent where, not the route taken (see Path for that). Colored in the same 8 equal bins as Path, but here the bins are by visit density, not time. Click a cell to seek the video to the first frame that landed there.
One row per hole, one mark per visit, left to right in time - click a mark to seek the video there.
About
One row per hole, target hole marked with a star (not color alone), trial start to end of recording left to right. Each mark is a real hole-visit, shaped by type (poke/entry/thigmotaxis) so meaning never depends on color alone. Click a mark, or focus the raster and use arrow keys plus Enter, to seek the video there - this tab, unlike Path and Heat map, is fully keyboard-operable.

Mouse tracking
Finds the mouse in each frame by comparing it against the empty-platform background, and marks a frame failed rather than guessing when it can't.
About
Background subtraction against the median, gated to the confirmed platform circle and a plausible size range. The largest matching blob wins each frame. A frame with no valid blob is marked failed, never guessed.
About
- Mask threshold
- How different from the empty-platform background a pixel has to be before it counts as mouse. Lower values pick up more of the animal but also shadows and lighting drift; higher values lose the animal in dimmer frames. The default of 30 tracked all three test clips despite very different lighting between the three rigs, which is the only evidence there is - no other value has been tested, and the 1-255 range is the arithmetic limit of an 8-bit image, not a tested range.
- Min blob area (px)
- Blobs smaller than this many pixels are rejected before the mouse is chosen. The default of 150 is already at the edge: test53's smallest observed mouse blob measures exactly 150, so partial views of the animal mid-poke are being clipped at the current setting. If tracking fails during hole investigations specifically, lowering this is the first thing to try. Raising it will lose more frames, not fewer.
- Max blob area (px)
- Blobs larger than this many pixels are rejected. The largest valid mouse blob observed across the three clips was 777 pixels, so the default of 1500 has roughly two-fold headroom; the fixed bolt this gate was added to exclude measured 3121, well above it. That gap is wide enough that this dial is unlikely to need changing, and no value other than 1500 has been tested.

Search strategy
Which search pattern this trial matches - spatial, serial, or random - or UNCLEAR when no single pattern fits.
About
Spatial (direct) / serial / random. The definitions of the three strategies come from Gawel et al. 2019 (Table 1, citing O'Leary & Brown), including the "at most 1-2 holes adjacent to the target" limit that decides Direct - those are the literature's, not invented here. The 0-1 scores and the two bars that gate them are this project's own, and are described in the threshold notes below. A verdict requires exactly one categorical pattern to match; otherwise it's UNCLEAR and all three scores are shown for you to audit against the hole sequence, rather than forcing a guess.
About
- Serial bar / Random bar
- A trial is called serial or random only if its respective score clears this bar. Unlike the strategy definitions themselves, these two numbers are not from the literature -
serialScoreandrandomScoreare this project's own 0-1 metrics (adjacency and direction consistency; platform-centre crossings), and the defaults of 0.6 and 0.5 are locally-set cutoffs on them. They were set from the shape of the literature's categories rather than calibrated, on the explicit reasoning that three test clips cannot calibrate a classifier. No value other than the defaults has been tested, and moving them is not a way to resolve an UNCLEAR verdict: a verdict also requires a categorical pattern match, so a score clearing its bar is necessary but not sufficient.

Trial summary
One spreadsheet row for this trial, with every measure, the search-strategy verdict, and the thresholds that produced them.
About
One tidy row for this trial: every measure above, the search-strategy verdict, the thresholds that produced them, and the tool version - opens directly in Excel, no legend needed. "Video file" is always included, so every exported row stays traceable on its own.
Event detail
Per-event detail: one row per hole visit (matches Merged Visits above, overrides included) - the "long form" alongside the trial summary's "short form."
Project file
Not spreadsheet data - a reloadable copy of this trial's own work, to resume later without re-tracking.
Save a portable _AUDITED.bmp.json file with everything except the video itself (which stays wherever it already lives) - open it later, on any computer, to resume without re-tracking. Save it in the same folder as the video, next to it - the name makes it obvious at a glance, to you or anyone else, that this trial's already been done.
