Self-study
One person, a browser, and public data. No cohort, no schedule.
For: Anyone working through the material on their own time, at any career stage.
The same material, three situations: working alone, running a hosted session, or inside a research programme.
The tracks answer what you are learning. They do not answer how you are using it, and that turns out to change almost everything about what the material needs to be.
A person working alone at midnight needs the answer to a self-check to be available and needs to be told not to open it yet. A facilitator standing in front of eleven people needs a run of show, a rubric visible before the activity starts, and a list of misconceptions to fish for in the debrief. A trainee inside a lab needs neither: they need work whose output somebody downstream actually uses, and a reviewer who will tell them it is not good enough.
Those are three different products built from one body of material. Treating them as one surface is why sites like this one usually end up serving none of them well: the units read as both self-study and lecture notes, and the facilitator material sits orphaned from the content it supports.
Mode is independent of track. Any track can be worked in any available mode, and each track page states what it looks like in each.

For: Anyone working through the material on their own time, at any career stage.
A facilitator runs a session. Timing, materials, and rubric are already written.
For: Instructors, mentors, and program staff running a taught session, a lab meeting, or a summer-program block.
A longer, contributory programme that draws on this material. Not built yet.
For: Trainees working inside a lab or programme on real data, producing work others will rely on.
One person, a browser, and public data. No cohort, no schedule.
You set the pace, choose the order, and mark your own work. Every unit is written to be readable without a lecturer standing next to it: worked examples run to completion, self-checks are answerable before the answer is revealed, and each lab ends in an artifact you can look at and judge.

Every module has a session kit: run of show with timings, prep checklist, the activity and its handouts, the misconceptions to surface in debrief, an assessment rubric, an exit prompt, and a page on what to do when the session goes wrong. The kits are generated from the module pages, so a session and its source material cannot drift apart.

The intended third mode is an intensive, research-and-contribution focused programme that uses this site as its reference layer rather than its syllabus: a cohort works on live data, contributes proofreading or analysis that is actually used, and is assessed on work that leaves the classroom. It does not exist yet. This entry is here so the gap is visible rather than implied.
A perceptual assessment on native-resolution data with labels derived from released segmentations, reporting accuracy within a learner's own high-confidence calls rather than raw accuracy. Units 05-07 argue calibration matters more than accuracy; the gate has to measure what the curriculum claims to value.
Proofreading or analysis work that someone downstream actually uses. Practice tasks whose output is discarded do not produce the thing this mode exists to produce.
A named reviewer, a rubric, and a return path. The worksheets already carry peer-review sections; what is missing is the exchange.
If you are unsure, you are almost certainly in self-study, and the question that matters more is which track. Pick that on the tracks page, or ignore the tracks and follow a question through the core.
