Reporting. The normalized score (SABR-P propensity) is plotted as a function of residue number from 1 to end of the sequence, i.e. as a “SABR-P propensity plot”. The actual predictions are also written out separately as text and these report only the amino acid residue (as G, A, V, etc.) along with the score, for those residues for which the normalized scores exceed 100. Particularly because of step (3), these will tend to occur conveniently in runs of approximately 8–18 contiguous residues, but sometimes shorter. In the present study the normalized score was formalized as a simple measure by rounding to the nearest integer prior to reporting, though this made no significant difference in the present paper.
