This is a list of tools we are cataloging as a convenience reference for NWB:N users. This is not a comprehensive list of NWB:N tools. Many of these tools are built and supported by other groups, and are in active development.

NWB Explorer

NWB Explorer is a web application developed by MetaCell for reading, visualizing and exploring the content of NWB 2 files. The portal comes with built-in visualization for many data types, and provides an interface to a jupyter notebook for custom analyses and open exploration.


Computational toolbox for large scale Calcium Imaging Analysis, including movie handling, motion correction, source extraction, spike deconvolution and result visualization. CaImAn now supports reading and writing data in NWB 2.0. NWB tutorial here.


Brainstorm is a collaborative, open-source application dedicated to the analysis of brain recordings: MEG, EEG, fNIRS, ECoG, depth electrodes and animal invasive neurophysiology built in Matlab and Java. Brainstorm now supports the NWB data format for importing ECoG and invasive electrophysiology data. The application provides a graphical interface for a preprocessing and analysis pipeline, including spike sorting using WaveClus, UltraMegaSort2000, KiloSort or Klusters, a large suite of spiking and LFP analyses, data visualization, and interactive visualization of anatomical topographies.


NWBwidgets is a library for exploring an NWB file in a Jupyter notebook. This tool lets you traverse the hierarchical structure of an NWB file and visualize the data from each of the NWB elements within the file.


EcogVIS is a Python-based, time series visualizer for Electrocorticography (ECoG) signals stored in NWB files. EcogVIS makes it intuitive and simple to visualize ECoG signals from selected channels, brain regions, make annotations and mark intervals of interest. Signal processing and analysis tools will soon be added.
