From: Simple adjustment of the sequence weight algorithm remarkably enhances PSI-BLAST performance
Relations between the ROC5 score improvement and the fraction of narrow blocks. The X-axis shows (number of one aa long blocks during PSSM construction)/(length of the query). The Y-axis shows the ROC5 score of PSI-BLASTexB replaced by that of PSI-BLAST. Each dot represents the result of a single query. The results of queries which have only one TP hit (self-hit) were ignored. Results of SCOP20_training (2752 queries), SCOP20_validation (2752 queries), and CATH20-SCOP (858 queries) at the second iteration are presented respectively in A, B, and C
