Extended Data Fig. 7: Performance of models fit to AbundancePCA data from combinatorial library 3.
a, Performance of first-order two-state thermodynamic model (folded and unfolded states) fit to AbundancePCA data from combinatorial library 3 (see Fig. 4). b–d, Performance of first-order (b), second-order (c) and third-order (d) linear models fit to AbundancePCA data from combinatorial library 3 (see Fig. 4). R2 is the proportion of variance explained.
