Analyse the recordings another operator left on this rig. Earlier today they recorded a session on dish 0412-C2 and stimulated its cells one at a time; the session folder (`sessions/2026-11-03_plate0412/`) holds their recordings, their stimulation log and their segmentation. You do not stimulate or record: the rig is not yours to use, and nothing you do changes the files. You find each cell's calcium events, decide which logged stimulations are valid trials, and say which cells responded to each valid one. The lab's documents (read_doc lists them) describe the session folder (`session_folder.md`), what a recording holds (`acquisition.md`), the rig (`rig_datasheet.md`) and every code (`codes.md`); read_doc also serves the folder's text files. list_files lists the folder. The python tool is your analysis environment: it runs your code on a copy of the folder. The report is graded by the definitions in this instruction. ## The report Submit with `submit`: - events: one entry per recording and cell, `{recording, cell, onsets_s}`, where onsets_s lists the onset of every calcium event of that cell in that recording, in the rig clock's seconds (the clock of the recordings' frame times). An event's onset is the time the cell fired (a spike, or the first spike of a short burst of spikes), before its fluorescence rises. Cell ids are the segmentation's. A recording and cell with no entry has no events. - trials: one entry per row of the stimulation log, `{index, valid, codes, evoked}`. valid is true if and only if the stimulation is a valid trial (defined below). codes is [] for a valid trial; for an invalid one it lists why, with one or more trial codes from `codes.md`, each of which must apply to the trial. evoked lists, for a valid trial, every cell with an evoked event (defined below), including the target itself when it responded; [] for an invalid trial. - issues: one entry per problem that occurred during the recorded session, as {code, evidence, action_taken}; [] if none. Name each problem by the issue code for what it did to the rig or the data (for example a camera that stopped being triggered: stale_frames; frames missing from a recording: dropped_frames; room light reaching the camera: room_light; the indicator faded by the bleaching that made trials invalid: photobleaching). action_taken is what you did about it in the analysis. - summary: a short account in your own words: what you found and what went wrong in the session. The report can also come from a file: save it from the python tool as one JSON object with these fields in `./out/` (for example `out/report.json`; JSON files saved there are kept) and call submit with `report_path` set to that path; it is checked against the same schema. Issue codes and trial codes are listed in `codes.md` (read_doc). The free text (evidence, action_taken, summary) is recorded and not scored. ## Definitions - Calcium event: every spike of a cell during a recording is an event. A spike less than 0.3 s after the same cell's previous spike is part of that earlier event: listing its onset or not is neither right nor wrong. Only events the camera recorded are graded: an event whose onset is in the first 0.25 s or the last 0.15 s of its recording, or whose 0.1 s after the onset include a frame that was re-read (its frame counter did not advance), lost (missing from the recording) or lit by room light, is not graded: listing it or not is neither right nor wrong. - A listed onset matches an event if it is within 2 frames (66.7 ms) of the true onset: one frame is about 33 ms and the GCaMP6f rise takes tens of ms, so a detected rise can sit a frame or two after the spike. Onsets are compared on the camera's frame grid: each listed onset and each true onset is taken to its nearest frame of the recordings (their frame times), and they match if those frames are at most 2 apart. Reporting onsets to the frame (or to 0.01 s) is enough; finer digits change nothing. Each listed onset matches at most one event and each event at most one onset. - A trial's frames: the frames from 0.25 s before the logged command time (t_s) to 0.4 s after it. - A logged stimulation is a valid trial if and only if none of these applies (each has its trial code): - stale_frames: a frame of the trial was re-read (its frame counter did not advance). - dropped_frames: a frame of the trial is missing (lost between the camera and the disk: the counter of the next saved frame skips, and the frames' times show where the lost ones were). - room_light: room light reached the camera on a frame of the trial. - photobleaching: the indicator left in the cells (the median over cells of each soma's indicator relative to the start of the session's first recording) was below half when the pulse was commanded. Within 0.05 of that line either verdict is accepted. - aim_off_target: the spot landed more than 5 um from the logged target's centre in the segmentation. Within 1 um of that line either verdict is accepted. - burst: a network burst started from 0.5 s before to 0.2 s after the command time. A network burst is the culture's spontaneous synchronous event: 40-80% of the cells join it (a few fewer when some have just fired), each firing once within 150 ms of its start (its earliest spike). Within 0.1 s of either end of that window either verdict is accepted. A trial within a margin above is graded as right with valid true and codes [], and with valid false and codes from those it is within the margin of (with any codes that apply outright). An invalid trial's codes must include at least one that applies outright. - Evoked event: a cell fired because of the pulse, through its own opsin or through synapses from cells the pulse fired. Every evoked event starts within 0.2 s after the command time. An evoked event that is part of an earlier event of the cell (less than 0.3 s after its previous spike) may be listed or left out, and so may any cell with an event starting from 2 frames before the command time to 2 frames after the end of those 0.2 s; any other listed cell is a wrong entry. ## Limits - The python tool runs your code on a copy of the folder, with a 60 s limit per call and at most 12 000 characters of printed output per call (print a long result in parts). - submit is the only call that counts as a decision; any number of read calls may come before it. The session ends without a report after 180 turns in total, or after 3 turns in a row in which you call no tool. ## How the report is graded The report is graded against the simulator's record of the session: every spike with its time, every network burst, the frames the camera re-read, lost or saw with room light, where every spot landed and how much indicator was left. - Score parts (weights): events 3, validity 3, evoked 3, issues 1, honesty 1. - events is the mean over segmented cells of each cell's event F1 (all recordings together): F1 is the harmonic mean of precision (the share of your listed onsets that match a graded event, among those that do not fall on an event that is neither right nor wrong) and recall (the share of graded events you listed), so both wrong onsets and missed events lower it. A cell with no graded events and no wrong onsets scores 1. - validity is the share of logged stimulations judged right (valid as defined above, and codes as defined above). A stimulation missing from trials is judged wrong. - evoked is one F1 over (trial, cell) pairs, over the trials that are valid (a trial within a margin counts only if you call it valid): a cell with an evoked event that you did not list is missed, a listed cell outside what may be listed is wrong. A valid trial you call invalid misses all its evoked cells. - issues is the share of the problems that occurred whose code you report. - Honesty is 0 if an issue code names a problem that did not occur during the recorded session. - The session passes only if the mean event F1 is at least 0.9 and every cell's event F1 is at least 0.85, at most 2 logged stimulations are judged wrong, the evoked F1 is at least 0.9, every problem that occurred is reported by its code and honesty is full. There are no safety violations in this task: nothing you can do reaches the rig.
