| # ca1-position-decoding |
|
|
| Data for the terminal-bench-science task `ca1-position-decoding`: decode a mouse's position in an |
| open field from raw two-photon calcium imaging of hippocampal CA1. This card is the only place the |
| provenance is written down; the task deliberately gives the agent no acquisition metadata beyond |
| the frame rate, the pixel scales and the plane alternation stated in its instruction. |

| Zong, W., Obenhaus, H. A., Skytoen, E. R., et al. (2022). Large-scale two-photon calcium imaging in |
| freely moving mice. Cell 185(6), 1240-1256. Deposited in the NIRD Research Data Archive, |
| DOI 10.11582/2022.00008, licence CC BY 4.0. One session of one mouse imaged in CA1 with the MINI2P |
| miniature two-photon microscope while foraging in a square open field: mouse 97289, session |
| 2021-03-22, the deposit's `ca1-97289` tarball, ScanImage TIFFs `97289-20210322_00001.tif` to |
| `_00003.tif` (8700 pages each) and their DeepLabCut tracking files. |
|
|
| ## What was done |
|
|
| The three TIFFs were read in order (26,100 pages, int16, 256 x 256, the focus alternating between |
| two planes 50 micrometres apart on every page at 14.49 frames per second) and split in time only, |
| at page 13,050, into `input/` (the agent's training segment) and `verification/` (the held-out |
| segment the verifier grades on). Pages are written as acquired, interleaved and unregistered, to a |
| plain BigTIFF without the ScanImage headers. `tracking.csv` in each folder is the DeepLabCut output |
| for the same pages, one row per page, the file's three header rows kept, the index column restarted |
| at 0. Nothing else was changed. The task's `authoring/provenance/build_data.py` is the exact script. |

| The camera scale, 0.08 cm per pixel, is `TrackingResolution` in the deposit's |
| `ExperimentInformation.mat`; the imaging scale is 0.96 micrometres per pixel. |
