# CoPeP Continual Protein Dataset

This dataset is organized for continual-learning experiments on protein sequences.

## File layout

- `train/`: 252 parquet shards (`data-00000-of-00252.parquet` ... `data-00251-of-00252.parquet`)
- `splits/`: 10 task index parquet files (`task_0.parquet` ... `task_9.parquet`)
- `val/`: validation parquet (`val.parquet`)

## Task file mapping

- `task_0.parquet` -> task_0 (2015)
- `task_1.parquet` -> task_1 (2016)
- `task_2.parquet` -> task_2 (2017)
- `task_3.parquet` -> task_3 (2018)
- `task_4.parquet` -> task_4 (2019)
- `task_5.parquet` -> task_5 (2020)
- `task_6.parquet` -> task_6 (2021)
- `task_7.parquet` -> task_7 (2022)
- `task_8.parquet` -> task_8 (2023)
- `task_9.parquet` -> task_9 (2024)

## Important note on `splits/task_*.parquet`

The `splits/task_*.parquet` files are index-style split definitions keyed by `row_idx`.
They are intended to be joined with records from `train/` using `row_idx`, rather
than treated as standalone full-example datasets.

## Basic code: load one task index split

```python
from datasets import load_dataset

repo_id = "anon2435/CoPeP"

# 1) Load train split directly.
train_ds = load_dataset(repo_id, split="train")

# 2) Load one task index split via the task_splits config.
task0_idx = load_dataset(
    repo_id,
    name="task_splits",
    split="task_0",
    streaming=True,
)

# 3) Materialize examples by selecting train rows using row_idx.
task0_rows = [example["row_idx"] for example in task0_idx]
task0_examples = train_ds.select(task0_rows)

print(task0_examples)
print(task0_examples[0])
```
