$cluster: c1-c4=clusters 1-4 c1-10=cluters 1-10 *For human area 24 posterior subclustering c1-7=cluters 1-7 *For marmoset LFC clustering

$rois Au1 = primary auditory cortex PPC = posterior parietal cortex S1 = primary somatosensory M1 = primary motor Amygdala = Amygdala Insula = Insula striatum = striatum 1-10 = 1-10 human area 24 posterior

Description of contained files: $species_$cluster_map: .nii.gz seed resting state maps from each of the 4 clusters, in each species

$species_$roi: .nii.gz files of individual ROIs in respective template spaces

$speciesmfc$cluster: clustering solutions for each species

$species_$cluster_24p: .nii.gz seed resting state maps from each of the 10 area 24p subclusters

$species_$roi_24p_roi: .nii.gz files of individual ROIs for each of the 10 area 24p subclusters

$speciesLFC$cluster_LFC: .nii.gz seed resting state maps from each of the 7 marmoset LFC clusters

*Marmoset LFC clustering solutions provided in previous manuscript, see https://gin.g-node.org/everling_lab_marmosets/Marmoset_LFC_funcitonal_boundaries

*To derive fingerprints and resultant cosine similarity, please use publicly available code as follows:

  1. Extract timecourse from each roi (from RS maps): https://afni.nimh.nih.gov/pub/dist/doc/program_help/3dmaskave.html

  2. Normalize; in matlab: e.g., r_mfc_c1 = rescale(dlmread('r_mfc_c1.txt')

  3. Calculate cosine similarity: https://www.mathworks.com/matlabcentral/fileexchange/62978-getcosinesimilarity-x-y

  4. Plot fingerprint: https://www.mathworks.com/matlabcentral/fileexchange/30305-spider-rader-chart-for-multi-data
