New finite-size correction for local alignment score distributions

BMC Research Notes

Table 1 Retrieval accuracy for different subsets of SCOP database with the new and old finite-size correction

Method	25^th percentile	50^th percentile	Full database
New correction	0.10373 ± 0.00022	0.10073 ± 0.00019	0.08535 ± 0.00013
Old correction	0.09201 ± 0.00020	0.09282 ± 0.00017	0.08358 ± 0.00014

The three subsets contain proteins shorter than 91 residues (25^th percentile by length), shorter than 137 residues (50^th percentile by length), and the full database. ROC-4852 scores are presented with an error (one standard deviation). The 25^th percentile database contains 2533 sequences, the 50^th percentile database contains 5008 sequences, and the full database contains 10,569 sequences. There are 4852 queries.
