Weegit

Introduction

Weegit is a cross-platform desktop application for viewing and labeling electrophysiology data (EEG, patch-clamp, multielectrode recordings, and similar signals).
It supports Windows, macOS, and Linux.

Weegit stores data in its own folder layout:

$EXPERIMENT_weegit
├── header.json
├── data
│   ├── sweep_00000
│   │   ├── 0.wsd
│   │   ├── ...
├── sessions
│   ├── $SESSION_NAME.json
├── add_ons
│   ├── data
│   │   ├── $ADD_ON_MODULE_NAME

Run GUI

Developers

Convert source data to Weegit format

from pathlib import Path
from weegit.converter.weegit_io import WeegitIO

path_to_parent = Path("/path/to/parent/dir")
exp_name = "20252222"
exp_dir = path_to_parent / exp_name
out_weegit_folder = path_to_parent / f"{exp_name}_weegit"

for progress in WeegitIO.convert_from_source_to_weegit(exp_dir):
    print(f"\rProgress: {progress}%", end="", flush=True)

print("Created:", out_weegit_folder)

Supported import formats include old Weegit and Intan RHS (XDAQ).

Create add-ons from GUI

1. Open Weegit.
2. Go to Add-ons > Create.
3. Fill:
   • project metadata (name, description, authors)
   • capability flags (viewable, transformation, runnable)
4. Click Generate template.
5. Implement add-on logic in generated add_on_development/example.py.
6. Add metadata/entry point in generated add_on_development/pyproject.toml.

Generate a script with current Weegit API

1. Go to Add-ons > Generate script.
2. Fill:
   • Weegit folder (*_weegit)
   • Session name (without .json)
   • output .py file path
   • optional blocks (events, periods)
3. Run generated script with the same Python environment where Weegit is installed.

Generated script demonstrates:

• loading experiment data through WeegitSessionManager
• reading raw channel slices from data_memmaps[sweep_idx][channel_idx]
• conversion to voltage values via from_int16_to_voltage_val(...)
• loading a GUI session via UserSession.session_name_to_filename(...)
• iterating events through session.user_session.events_table
• iterating periods through session.user_session.periods
