# Track ENCODE Experiments ## When to Use - User wants to save/bookmark ENCODE experiments for later reference - User needs to build a collection of experiments for a project - User asks to "track", "save", or "bookmark" an experiment - User wants to manage citations and publications for ENCODE data - User needs to compare experiments for compatibility - User wants to export their experiment collection as CSV/TSV/JSON - User asks about data provenance (linking derived files to ENCODE sources) Help the user manage their local collection of ENCODE experiments. This skill covers the full lifecycle of experiment management: discovery, tracking, annotation, citation, comparison, provenance, and export. ## Tracking Capabilities 1. **Track an experiment**: Use `encode_track_experiment` to save experiment metadata, publications, and pipeline info locally. - Automatically extracts GEO accessions and PMIDs from experiment metadata - Fetches associated publications with authors, journal, DOI - Stores 18 metadata fields per experiment (see schema below) - Idempotent: re-tracking the same accession updates metadata without creating duplicates 2. **View tracked collection**: Use `encode_list_tracked` to see all tracked experiments. Filter by assay, organism, or organ. 3. **Get citations**: Use `encode_get_citations` to export publication data. - `"json"`: Structured data - `"bibtex"`: For LaTeX/reference managers - `"ris"`: For Endnote, Zotero, Mendeley 4. **Co
