# Commands to run (Spec-RAG retrieval + sanity check + oracle)

Paths below use your env: `Spec-RAG`, `SpecBridge`, `De-SpecBridge`, `MassSpecGym_test.mgf`, and `out/retrieval/`.

---

## Improving retrieval performance (candidates_A / candidates_B)

- **`--ef-search 512`** (default): Higher FAISS HNSW `ef_search` at query time improves ANN recall. Increase to 1024 if you need better recall and can afford slower search.
- **`--formula-filter`**: When MGF has `FORMULA`/`formula`, restricts candidates to same-formula molecules (over-fetches from FAISS then reranks). Use this so Recall/Tanimoto improve when the library contains same-formula molecules.
- **`--chemberta-model`**: Must match the model used to build the library (`build_library.py --chemberta-model`). Default `Derify/ChemBERTa_augmented_pubchem_13m`. If your SpecBridge checkpoint was trained with a different ChemBERTa, set this and rebuild the library with that model.
- **Formula over-fetch**: `--formula-min-fetch`, `--formula-max-fetch`, `--formula-fetch-multiplier` control how many vectors are fetched when using `--formula-filter`; higher values can improve recall when formula buckets are large.
- **Rebuild FAISS with higher quality**: `python scripts/build_faiss.py --library-dir ... --ef-search 256` (default is now 256) before retrieving.

---

## 1) Build library (once)

```bash
cd /cluster/tufts/liulab/yiwan01/Spec-RAG

python scripts/build_library.py \
  --smiles-path /cluster/tufts/liulab/yiwan01/De-SpecBridge/data/pubchem_clean.smi \
  --out-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge
```

---

## 2) Build FAISS indices

```bash
python scripts/build_faiss.py \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library
```

---

## 3) Train mappers (only if using Variant A without --smited-mapper-ckpt)

```bash
python scripts/train_mapper.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_train.mgf \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --out-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/mappers \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge
```

---

## 4) Retrieve (Variants A, B, C)

**Variant A (SMI-TED only; pretrained mapper):**

```bash
python scripts/retrieve_generate.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --smited-mapper-ckpt /cluster/tufts/liulab/yiwan01/De-SpecBridge/runs/smited_mapper_final/mapper_best.pt \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge \
  --variant A \
  --K 100 \
  --ef-search 512 \
  --formula-filter \
  --out-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_A.jsonl
```

**Variant B (ChemBERTa retrieval; no mapper-dir needed):**

```bash
python scripts/retrieve_generate.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --variant B \
  --K 100 \
  --ef-search 512 \
  --formula-filter \
  --chemberta-model Derify/ChemBERTa_augmented_pubchem_13m \
  --out-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_B.jsonl
```

**Variant B formula-keyed candidate-pool mode (direct exact rerank inside the provided candidate pool; no dependency on library overlap, and no FAISS needed unless a query falls back):**

```bash
python scripts/retrieve_generate.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --variant B \
  --K 100 \
  --formula-filter \
  --candidate-json /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_retrieval_candidates_formula.json \
  --candidate-key-field formula \
  --out-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_B_benchmark.jsonl
```

`--candidate-key-field smiles_gt` is still supported, but it is oracle-only benchmarking because it selects the candidate pool using the ground-truth molecule.

**Variant C:**

```bash
python scripts/retrieve_generate.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --variant C \
  --K 100 \
  --out-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_C.jsonl
```

---

## 5) Evaluate spectrum-based retrieval (Recall + Tanimoto)

```bash
python scripts/evaluate_massspecgym.py \
  --pred-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_A.jsonl \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/metrics_A.json \
  --tanimoto

python scripts/evaluate_massspecgym.py \
  --pred-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_B.jsonl \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/metrics_B.json \
  --tanimoto

python scripts/evaluate_massspecgym.py \
  --pred-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_C.jsonl \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/metrics_C.json \
  --tanimoto
```

---

## 6) Self-retrieval sanity check (Priority 2) — true mol embeddings

Index = test molecules only; query = same true molecule embeddings. **Expected Recall@1 ≈ 1.0** for both.

- If either fails → that embedding/index pipeline is broken.
- If ChemBERTa passes and SMI-TED fails → SMI-TED embedding issue.
- If both pass → issue is likely library coverage / eval mismatch.

```bash
python scripts/self_retrieval_sanity_check.py \
  --pred-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_B.jsonl \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/self_retrieval_report.json
```

(You can use any of `candidates_A.jsonl`, `candidates_B.jsonl`, or `candidates_C.jsonl`; they share the same `smiles_gt` per row.)

---

## 6b) Mapped-embedding self-retrieval sanity check

Index = **spectrum→mapper** embeddings of test set (same MGF); query = same mapped embeddings. **Expected Recall@1 ≈ 1.0.**

- Tests spectrum→ChemBERTa-mapped (SpecBridge) and spectrum→SMI-TED-mapped (DreamsToSmiTed or M_smi).
- If either fails → spectrum→mapped-embedding pipeline is broken.

```bash
# With De-SpecBridge SMI-TED mapper (recommended)
python scripts/self_retrieval_mapped_sanity_check.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --smited-mapper-ckpt /cluster/tufts/liulab/yiwan01/De-SpecBridge/runs/smited_mapper_final/mapper_best.pt \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/self_retrieval_mapped_report.json
```

If you use Spec-RAG mappers instead of the pretrained SMI-TED mapper:

```bash
python scripts/self_retrieval_mapped_sanity_check.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --mapper-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/mappers \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/self_retrieval_mapped_report.json
```

---

## 6c) True-index + Mapped-query sanity check

**Index** = true molecule embeddings (ChemBERTa/SMI-TED of test SMILES). **Query** = mapped embeddings (spectrum → mapper). So we build a tiny index from the test set’s true mol embeddings, then query with the spectrum→mapper embeddings. This tests how well the mapper aligns spectrum to molecule space (Recall@1/10/50).

```bash
python scripts/sanity_check_true_index_mapped_query.py \
  --mgf-path /cluster/tufts/liulab/yiwan01/SpecBridge/data/MassSpecGym_test.mgf \
  --specbridge-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/runs/specbridge_align_chemberta_pub_v3g_msgym_mapper_spec/ckpt_001200.pt \
  --dreams-ckpt /cluster/tufts/liulab/yiwan01/SpecBridge/data/ssl_model.ckpt \
  --smited-mapper-ckpt /cluster/tufts/liulab/yiwan01/De-SpecBridge/runs/smited_mapper_final/mapper_best.pt \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/true_index_mapped_query_report.json
```

---

## 7) Oracle retrieval (true mol embedding vs library)

```bash
python scripts/evaluate_oracle_retrieval.py \
  --pred-jsonl /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/candidates_B.jsonl \
  --library-dir /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/library \
  --despecbridge-path /cluster/tufts/liulab/yiwan01/De-SpecBridge \
  --K 100 \
  --report /cluster/tufts/liulab/yiwan01/Spec-RAG/out/retrieval/metrics_oracle.json
```
