AUNA (AUdio and Nerual Activity) is a graphic tool for marking audio events and analizing the neural data simultaneously recorded. It is currently an alpha version.

Requirements

  • MATLAB >= 9.6 (R2019a)
  • Signal Processing Toolbox
  • Image Processing Toolbox
  • Statistics and Machine Learning Toolbox

Installation

Add folder and subfolders to the Matlab path.
MAtNWB has to be installed to open NWB files. This can be done by running:

!git clone [https://github.com/NeurodataWithoutBorders/matnwb.git](https://github.com/NeurodataWithoutBorders/matnwb.git)  
cd matnwb  
addpath(genpath(pwd));  
generateCore();

Instructions

Configure the parameters in the par_auna.m file, go to the folder with the data and then run auna in the command window. The events and zones are saved insiede the file auna_data.mat.

Files

Audio file

AUNA loads the audio from a binary file NSX[channel_number].NC5 with values in int16. The metadata will be loaded from from a file named NSX_TimeStamps.mat with the variables sr (sampling rate in Hz) and lts (number of samples) . If a file NSx.mat is found in the path, AUNA will try to load the channel using the metadata table in that file.

Units files

If par.neuroformat = WC: The units activity will be loaded from the files: times_[channel_number].mat If par.neuroformat = NWB: The units activity will be loaded from the files: 'chan_[channel_number].nwb

Session configuration and events

By default the annotations are saved inside the file auna_data.mat. The zones structure has a field for each zone with its limits and pre/post times to create rasters. The concepts struct has a field for each concept with times in ms for each annotation.

Shortcuts

  • numerical minus('-'): maximum timescale (zoom out icon)
  • space bar: pause/resume (||)
  • right_arrow: next data block (>>)
  • left_arrow: prev data block (<<)
  • return: Add mark
  • 1-9: choose the event number
