Rename deprecated BNCI2014001 to BNCI2014_001

[Copilot]

MOABB deprecated BNCI2014001 in favor of BNCI2014_001 and will remove the old name in v1.1.

Changes

• Class definition: Renamed BNCI2014001 → BNCI2014_001 in braindecode/datasets/moabb.py
• Dataset string references: Updated all dataset_name="BNCI2014001" → dataset_name="BNCI2014_001" across examples and tests (7 example files, 4 test files)
• Imports: Updated imports and __all__ exports in braindecode/datasets/__init__.py
• Documentation: Updated API reference in docs/api.rst

Migration

Old code:

from braindecode.datasets import BNCI2014001
dataset = BNCI2014001([1])
# or
dataset = MOABBDataset(dataset_name="BNCI2014001", subject_ids=[1])

New code:

from braindecode.datasets import BNCI2014_001
dataset = BNCI2014_001([1])
# or
dataset = MOABBDataset(dataset_name="BNCI2014_001", subject_ids=[1])

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• bnci-horizon-2020.eu
  • Triggering command: python -m pytest test/unit_tests/datasets/test_moabb.py::test_BNCI2014_001 -v (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
