“…We introduce the abagen toolbox, an open-access software package designed to streamline processing and preparation of the AHBA for integration with neuroimaging data ( Markello et al, 2021c , available at https://github.com/rmarkello/abagen ; Markello, 2021b copy archived at swh:1:rev:2aeab5bd0f147fa76b488645e148a1c18095378d ). Supporting several workflows, abagen offers functionality for an array of analyses and has already been used in several peer-reviewed publications and preprints ( Shafiei et al, 2020 ; Hansen et al, 2021 ; Shafiei et al, 2021 ; Brown et al, 2021 ; Park et al, 2021 ; Valk et al, 2021 ; Zhao et al, 2020 ; Benkarim et al, 2020 ; Ding et al, 2021 ; Park et al, 2020 ; Lariviere et al, 2020 ; Martins et al, 2021 ). The primary workflow, used to generate regional gene expression matrices, integrates 17 distinct processing steps that have previously been employed by research groups throughout the published literature ( Table 1 ).…”
