Development of the Complex General Linear Model in the Fourier Domain: Application to fMRI Multiple Input-Output Evoked Responses for Single Subjects

Algorithm 1

Input: Select multiple 𝑃-values𝑃₀,…,𝑃_𝑛 and associated color values in LUT

Calculate corresponding 𝐹-value, 𝐹(𝑃₀),…,𝐹(𝑃_𝑛)∣ dof (2𝑏𝑐; 2ℎ)

Loop over voxels within brain mask

 Extract 𝐹-values at voxel, indexed by band numbers

 Loop over band numbers

  Get 𝐹 for band

    if (𝐹<𝐹(𝑃₀) maskPixel = 0

    if (𝐹≥𝐹(𝑃₀) and 𝐹<𝐹(𝑃₁)) maskPixel = 1

    ⋮

    if (𝐹≥𝐹(𝑃_𝑛−1) and 𝐹<𝐹(𝑃_𝑛)) maskPixel = 𝑛

    if (𝐹≥𝐹(𝑃_𝑛)) maskPixel = 𝑛+1

 End loop over band numbers

End loop over image voxels

Output: multi-value mask and associated color LUT
