np_nwb's Introduction

np_nwb

Tools for quickly generating .nwb files from non-standard Mindscope Neuropixels experiments.

Generating an .nwb file will entail:

inputting a path to a folder of raw data from a single experiment (session_folder)
creating an instance of pynwb.NWBFile and writing to disk (nwb_file)
passing nwb_file + session_folder, to various modules that add nwb components
each module should:
- accept or load an instance of pynwb.NWBFile from nwb_file
- recognize the type of experiment contained in session_folder
- process raw data in session_folder accordingly
- append tables to the pynwb.NWBFile instance
- optionally write to disk
- return the pynwb.NWBFile instance

Each module should therefore provide a single function or method which implements the following append() interface:

import logging
import pathlib
import tempfile
from typing import Optional

import np_tools
import pynwb

logger = logging.getLogger(__name__)


def append(
    session_folder: str | pathlib.Path,
    nwb_file: str | pathlib.Path | pynwb.NWBFile,
    output_file: Optional[str | pathlib.Path] = None,
    ) -> pynwb.NWBFile:
    """Append one or more new components to an `.nwb` file.

    - callable from within a Python process, by accepting & returning instances of `pynwb.NWBFile` 
    - callable from the command line, in which case all three input arguments are required, with `nwb_file` specified as a path
    """
    session_folder = pathlib.Path(session_folder)

    # ... process session_folder

    if not isinstance(nwb_file, pynwb.NWBFile):
        nwb_file = np_tools.load_nwb(nwb_file) 
    
    # ... append new components to nwb_file

    if output_file is not None:
        np_tools.save_nwb(nwb_file, output_file)
    
    return nwb_file
