“…However, most of the recent focus has been on the development of computational tools for predicting intrachain (within the same chain) residue-residue contacts and distances to guide tertiary structure modeling (Hopf et al, 2014; Zhou et al, 2018). Some of these methods have performed well in the 12 th and 13 th Critical Assessment of Techniques for Protein Structure Prediction (CASP) competitions (Adhikari et al, 2018; Alquraishi & Valencia, 2019; Cheng et al, 2019; J. Hou et al, 2020; Schaarschmidt et al, 2018; Senior et al, 2020; Shrestha, Fajardo, Gil, Fidelis, Kryshtafovych, Bohdan Monastyrskyy, et al, 2019; Shrestha, Fajardo, Gil, Fidelis, Kryshtafovych, Monastyrskyy, et al, 2019; Wang et al, 2017, 2018; Xu & Wang, 2019).…”
