kMindConnect is a software package developed with the aim of offering seamless integration between different the Brain dynamic connectivity modelling and the visualization results. The toolbox provides an easy way to present the dynamic changes in the estimated Brain states (or connectivity.) The default model to perform this estimation inside the application is the switching-regime vector autoregressive model (S-VAR) that is fitted over clustered time-varying vector autoregressive (TV-VAR) coefficients from the data input [Ombao et al., 2018] [Ting et al., 2018] [Pinto et al., 2018][Ting et al., 2016].

Preparing the environment on Ubuntu/Debian

  • Step 1: Install Octave
    sudo apt install octave octave-signal octave-statistics
  • Step 2: Install Anaconda/Python3
  • Step 3: Install additional Python packages
    pip install oct2py 
    conda install plotly
    conda install docopt
  • Step 4: Install node and electron (Only for building the software)
    sudo apt install node
    sudo npm install -g electron --unsafe-perm=true --allow-root
