“…One of the greatest challenges today is to develop approaches allowing the useful exploitation of large-scale datasets in biomedical research in general ( Margolis et al, 2014 ) and neuroscience and neuroimaging in particular ( Van Horn and Toga, 2014 ). Progress in this direction is made possible by the increasing availability of large public datasets in the domain of connectomics ( Van Essen et al, 2013 ; Poldrack and Gorgolewski, 2014 ; Horien et al, 2021 ). This is true, in particular, for research in Alzheimer’s disease (AD), in which, despite decades of massive investment and a daunting literature on the topic, the partial and, sometimes contradictory nature of the reported results ( Patterson, 2018 ) still prevents a complete understanding of the factors governing the progression of the disease ( Braak and Braak, 1991 ; Braak et al, 2006 ; Komarova and Thalhauser, 2011 ; Henstridge et al, 2019 ) or of the diversity of cognitive deficits observed in different subjects ( Iacono et al, 2009 ; Mungas et al, 2010 ; Allen et al, 2016 ).…”
