# DynaRepo MDPosit

This repository mirrors Molecular Dynamics (MD) project metadata and files laid out per accession as exposed by Dynarepo. It includes global and per-accession manifests, project-level JSON, and the actual files (structures, trajectories, derived PCA binaries, and analysis screenshots). Field names and shapes follow Dynarepo’s documented model.


## Overview

### How to consume

- **Stream-parse**: Read the file line-by-line and `json.loads` each object to enumerate replicas and their artifacts.
- **Relate to `project_example.json`**: Each line mirrors an item in `flattened_md_records` and can be joined back to project-level fields if needed.
- **Concatenate across accessions**: You can build a global manifest by concatenating multiple `data\files\<ACCESSION>\records.jsonl` files.
- **Field semantics**: Follow the Dynarepo docs: [Meta](https://dynarepo.inria.fr/#/meta), [Statistics](https://dynarepo.inria.fr/#/statistics), [Help](https://dynarepo.inria.fr/#/help).


## Understanding `all_records.jsonl` (global flattened per-accession manifest)

- **Source**: Global, line-delimited aggregation of per-replica records across all accessions. See: [Dynarepo Meta](https://dynarepo.inria.fr/#/meta), [Dynarepo Statistics](https://dynarepo.inria.fr/#/statistics), and [Dynarepo Help](https://dynarepo.inria.fr/#/help).
- **Where it lives**: `data\files\all_records.jsonl`.
- **What it is**: A JSON Lines file where each line mirrors a single replica entry from per-accession `records.jsonl` (fields include `project_identifier`, `accession`, `md_index`, `md_name`, `analyses`, `metadata`, and `files`).
- **How to use**: Stream-parse line by line, filter by `accession` or `analyses`, and group by `accession`/`md_index` to enumerate all replicas and their artifacts across the dataset. Field semantics are identical to per-accession records and follow Dynarepo docs.

## Remote folder contents in `data\files\<ACCESSION>` (A0098 example)

- **Source**: Mirrors the per-accession file repository exposed by Dynarepo. See: [Dynarepo Meta](https://dynarepo.inria.fr/#/meta), [Dynarepo Statistics](https://dynarepo.inria.fr/#/statistics), and [Dynarepo Help](https://dynarepo.inria.fr/#/help).
- **Where it appears**: Under `data\files\<ACCESSION>\` in this repository; corresponds to Dynarepo’s remote path `/projects/<ACCESSION>/files`.
- **What you will typically find** (A0098 shown):
  - Core descriptors: `project.json` (~5.18 kB), `records.jsonl` (~43.3 kB)
  - Core MD simulation assets: `topology.tpr` (~1.71 MB), `structure.pdb` (~397 kB), `trajectory.xtc` (~93.5 MB), `trajectory.bin` (~294 MB)
  - PCA-derived binaries: `pca_trajectory_01.bin` … `pca_trajectory_05.bin` (5 files, ~237 kB each)
  - Cluster analysis screenshots:
    - `clusters_00_screenshot_00.jpg` … `clusters_00_screenshot_20.jpg` (21 images, ~16–21 kB each)
    - `clusters_01_screenshot_00.jpg` … `clusters_01_screenshot_19.jpg` (20 images, ~16–21 kB each)
  - Cover/preview: `screenshot.jpg` (~20.7 kB)
- **Relationship to manifests**:
  - Every file present under `data\files\<ACCESSION>\` is enumerated in that accession’s `records.jsonl` `files[]` entries with `name`, `downloadUrl` (relative to `/projects/<ACCESSION>/files/<name>`), `length` (bytes), and `contentType`.
  - The same inventory is summarized in `project.json` under its `files` section (e.g., `list`, `filenotes`, `merged`) and joined into `flattened_md_records` for per-replica views.
- **Notes**: Exact counts and sizes vary by accession and by which analyses were run; additional analysis types will add further artifacts alongside those listed above.

## Understanding `project.json` (Dynarepo dataset A0098)

- **Source**: Dataset metadata follows the Dynarepo model. See: [Dynarepo Meta](https://dynarepo.inria.fr/#/meta), [Dynarepo Statistics](https://dynarepo.inria.fr/#/statistics), and [Dynarepo Help](https://dynarepo.inria.fr/#/help).
- **Where it appears**: Each dataset under `data\files\<ACCESSION>` includes a project-level JSON with this schema. This repository provides a canonical example in `project_example.json`.
- **What it is**: A single, self-contained description of an MD project combining high-level project metadata, per-replica MD records, file inventory, topology, references, analysis results, and summaries. It is designed to be directly consumable by Dynarepo services and UIs.

### High-level structure

- **`project`**: Core project info and global metadata
  - Keys: `accession`, `published`, `metadata` (e.g., `NAME`, `DESCRIPTION`, `AUTHORS`, `PROGRAM`, `VERSION`, `TYPE`, `METHOD`, `LICENSE`, `PDBIDS`, `REFERENCES`, simulation params like `FRAMESTEP`, `TIMESTEP`, `TEMP`, `ENSEMBLE`, `FF`, `WAT`, box sizes, system counts), `mds` (replica names), `analyses` (available analysis types), `files` (canonical file names), `mdIndex`/`mdNumber`/`refframe`.
- **`flattened_md_records`**: One entry per MD replica with the replica’s `metadata` and a resolved `files` list including `downloadUrl`, `length`, and `contentType`.
- **`files`**:
  - `list`: canonical file names present in the project
  - `filenotes`: storage-level details (size, content type, upload date)
  - `merged`: convenient join of name, URL, size, and metadata
- **`topology`**: Atoms, residues, chains, bonding, and external references used to build the system.
- **`references`**: Protein and PDB references (e.g., UniProt IDs, sequences, domains) and cross-links to PDB entries.
- **`analyses`**: Machine-readable outputs per analysis (e.g., `clusters`, `dist-perres`, `energies`, `fluctuation`, `hbonds`, `interactions`, `pca`, `pockets`, `rgyr`, `rmsd*`, `sasa`, `tmscores`).
- **`summaries`**: Compact keys/metrics for quick inspection and validation.

### How this maps to datapoint A0098

- **Accession**: `A0098` (see `data\files\A0098\records.jsonl` for the per-replica lines used to populate `flattened_md_records`).
- **Project metadata examples** (from A0098):
  - `metadata.NAME`: "Dynarepo 5FZT"
  - `metadata.PDBIDS`: `["5FZT"]`
  - `metadata.REFERENCES`: `["P26039", "Q96QB1"]`
  - Simulation constants: `FRAMESTEP: 0.1`, `TIMESTEP: 2`, `TEMP: 310`, `ENSEMBLE: "NPT"`, `FF: ["CHARMM36m"]`, `WAT: "TIP3P"`, `BOXTYPE: "Dodecahedron"`
  - System scale: `mdFrames: 5001`, `mdAtoms: 4900`, `PROTRES: 329`, `SYSTATS: 4900`
- **Files commonly present**: `topology.tpr`, `structure.pdb`, `trajectory.xtc`, `trajectory.bin`, `pca_trajectory_*.bin`, and analysis screenshots (e.g., `clusters_*_screenshot_*.jpg`).
- **Analyses present**: `clusters`, `clusters-00`, `clusters-01`, `dist-perres`, `energies`, `fluctuation`, `hbonds`, `interactions`, `pca`, `rgyr`, `rmsd-pairwise`, `rmsd-perres`, `rmsds`, `sasa`, `tmscores`.

## Understanding `records.jsonl` (per-replica manifest in `data\files\<ACCESSION>`)

- **Source**: Per-MD replica records consistent with Dynarepo’s flattened MD model. See: [Dynarepo Meta](https://dynarepo.inria.fr/#/meta), [Dynarepo Statistics](https://dynarepo.inria.fr/#/statistics), and [Dynarepo Help](https://dynarepo.inria.fr/#/help).
- **Where it appears**: For each accession, a `records.jsonl` lives under `data\files\<ACCESSION>\`. This repository includes `data\files\A0098\records.jsonl`. A compact illustration is also provided at the repository root as `records._examplejsonl`.
- **What it is**: A JSON Lines file; each line describes one MD replica and its files.

### Record shape (keys you will see per line)

- **Top-level identifiers**: `project_identifier`, `accession`, `published`
- **Replica info**: `md_index` (0-based), `md_name` (e.g., "replica 1"), `chains` (if applicable)
- **Analyses available**: `analyses` (e.g., `clusters`, `rmsds`, `pca`, `sasa`, ...)
- **`metadata` object**: Biology and simulation parameters used by Dynarepo UIs and services. Common fields include `NAME`, `DESCRIPTION`, `AUTHORS`, `GROUPS`, `CONTACT`, `PROGRAM`, `VERSION`, `TYPE`, `METHOD`, `LICENSE` (and `LINKCENSE`), `PDBIDS`, `REFERENCES`, sequences/domains (`PROTSEQ`, `NUCLSEQ`, `DOMAINS`), simulation setup (`FRAMESTEP`, `TIMESTEP`, `TEMP`, `ENSEMBLE`, `FF`, `WAT`, `BOXTYPE`), system sizes (`SYSTATS`, `SYSTRES`, `PROTATS`, `PROTRES`, ...), optional `INTERACTIONS`, box sizes (`BOXSIZEX/Y/Z`), and per-replica summaries like `mdAtoms` and `mdFrames`.
- **`files` array**: One entry per stored artifact with `name`, `downloadUrl` (relative to `/projects/<ACCESSION>/files/<name>`), `length` (bytes), `contentType`, and a small `metadata` dict (e.g., `{project: <id>, md: <index>}` or per-file stats for derived binaries).

Typical files for A0098 include `topology.tpr`, `structure.pdb`, `trajectory.xtc`, `trajectory.bin`, `pca_trajectory_*.bin`, and analysis screenshots like `clusters_*_screenshot_*.jpg`.

### Contributing

When creating a new project JSON for another accession, minimally review/update:

- **Identifiers**: `project.accession`, `project.identifier`, and `metadata.NAME`
- **Biology**: `metadata.PDBIDS`, `metadata.REFERENCES` (UniProt), sequences/domains in `references`
- **Simulation**: `FRAMESTEP`, `TIMESTEP`, `TEMP`, `ENSEMBLE`, `FF`, `WAT`, box sizes, atom/residue counts
- **Replicas**: `mds` list and `flattened_md_records[*].md_index/md_name`
- **Files**: Ensure `files.list`, `files.merged`, and each replica’s `files[]` match your storage paths and sizes
- **Analyses**: Keep only the analyses you actually produced and include their data payloads

For reference on field meanings and expected shapes, consult the Dynarepo documentation: [Meta](https://dynarepo.inria.fr/#/meta), [Statistics](https://dynarepo.inria.fr/#/statistics), [Help](https://dynarepo.inria.fr/#/help).
