Neuroscience Data Readers - A Matlab conglomerative package for reading neuroscience data files
NDR-matlab is a package for reading neuroscience data files in a standard way. It includes some original code and some bundled code from other open source projects. It will eventually provide the file reading functionality for NDI (Neuroscience Data Interface) as NDI scales up but is available for use widely in many projects.
The package is focused around a central object called ndr.reader. This object can be used to read file metadata (such as the channels
that were turned on during the acquisition, the sampling rate, and other quantities) as well as file data.
The package is supported by a number of ndr.reader.* class objects that actually perform the reading of different file types in neuroscience.
It is intended that this package will be self-sufficient and not require other open source Matlab packages, although it does require some Matlab toolboxes from The MathWorks.
This package is being developed with a companion Python package NDR-python. Sometimes, the Matlab package may call the Python package if Matlab code is not available for a certain file format.
| Vendor/Format | Extension(s) | NDR Names | Support | Notes |
|---|---|---|---|---|
| Intan RHD | .rhd |
'Intan', 'IntanRHD', 'RHD' | Native Matlab | |
| CED Spike2/SMR | .smr |
'SMR', 'Spike2', 'CEDSpike2' | Native Matlab via sigTOOL (included) | |
| SpikeGadgets | .rec |

| Blackrock Microsystems | '.NEV', 'NS#' | 'BlackrockNEV', 'BlackrockNS4', 'BlackrockNS5' | Native Matlab via NPMK (from Blackrock Microsystems) (included) |
Dozens of other formats are supported via the integration with Neo-Python (see the list here - https://neo.readthedocs.io/en/stable/rawio.html#module-neo.rawio, note that NDR only suppports the Neo formats that implement RawIO).
This package has files from a variety of distributions. It is our intention to only distribute code that is in the public domain or is licensed for re-distribution. If you find your code here that is not properly distributed please notify the maintainer.
