### How to download

- **The dataset:** `nemar dataset download nm000173`. Clones and fetches in one step. Content under stimuli/ and derivatives/ is skipped by default because those trees can be large; add --stimuli --derivatives for the whole thing.
- **A subset, one step:** `nemar dataset download nm000173 --subjects sub-01,02`. Also filters by --sessions, --tasks, --runs, --datatypes, --include and --exclude.
- **A subset, step 1:** `nemar dataset clone nm000173`. Clones git-annex pointers only; fetches no file content. Creates ./nm000173.
- **A subset, step 2:** `cd nm000173`. The get command below reads the clone's annex, so it only works from inside the clone.
- **A subset, step 3:** `nemar dataset get <files>`. Pulls the files you actually need. Skips stimuli/ and derivatives/ unless the path you ask for is under one of them.
- **One small file:** [https://data.nemar.org/nm000173/v1.0.3/participants.tsv](https://data.nemar.org/nm000173/v1.0.3/participants.tsv). A direct HTTPS fetch works for any single file.
