More details on MFCSC and this tutorial can be found in the following paper:

Civier O, Sourty M, Calamante F (2023) MFCSC: Novel method to calculate mismatch between functional and structural brain connectomes, and its application for detecting hemispheric functional specialisations. Scientific Reports https://doi.org/10.1038/s41598-022-17213-z

In short, MFCSC calculates the mismatch between connectomes generated from different imaging modalities. It does it by normalising the connectomes to a common space calculated at group level, and taking into account the role of indirect connectivity in shaping the functional connectomes.

TUTORIAL FOR CONNECTOMES FROM fMRI AND dMRI

  1. Download the “input” folder from the OSF repository (https://osf.io/d7j9n/files/osfstorage)

  2. Launch mfcsc from either “Neurodesk”–>“Diffusion Imaging –> mfsc –> mfcsc 1.1” or “Neurodesk”–>“Functional Imaging –> mfcsc –> mfcsc 1.1” in the start menu.

  3. Run the following command with input being the directory where the input data was downloaded to, and outputdir being the directory where the output should be written to:

    mfcsc input/FC_SC_list.txt input/FC input/SC outputdir
  1. After MFCSC finishes running, the content of outputdir should be identical to the “output” folder in the OSF repository (https://osf.io/d7j9n/files/osfstorage) It contains connectomes that encode the mismatch between functional and structural connectivity (mFCSC) for every connection.

TUTORIAL FOR CONNECTOMES FROM MEG AND dMRI

  1. Use the MEG connectivity tutorial to generate functional connectomes from your MEG data using MNE tools on Neurodesk (Tutorial in progress: https://github.com/benmslade/neurodesk.github.io/blob/main/content/en/tutorials/electrophysiology/meg_connectivity.md)

  2. Use the structul connectivity tutorial to generate structural connectomes from your dMRI data using MRtrix tools on Neurodesk (https://www.neurodesk.org/tutorials-examples/tutorials/structural_imaging/structuralconnectivity/)

  3. Launch mfcsc from either “Neurodesk”–>“Diffusion Imaging –> mfsc –> mfcsc 1.1” or “Neurodesk”–>“Functional Imaging –> mfcsc –> mfcsc 1.1” in the start menu.

  4. Copy the MEG connectomes into input/MEG and the structural connectomes into input/SC

  5. Create an input/MEG_SC_list.txt file that lists the pairing between MEG and structural connectomes

  6. Run the following command with input being the directory where the input data was downloaded to, and outputdir being the directory where the output should be written to:

    mfcsc input/MEG_SC_list.txt input/MEG input/SC outputdir
  1. After MFCSC finishes running, outputdir will contains connectomes that encode the mismatch between MEG and structural connectivity (mFCSC) for every connection.
