Comparison of five methods in detecting WD40 repeats/domains/proteins from Swiss-Prot database with sequence length less than 2000 residues.

aExcept WDSP, if one WD40 repeat is detected, the protein is classified as containing at least one WD40 domain. For WDSP, each WD40 domain and WD40 protein has at least 6 WD40 repeats. If the total number of repeats in a protein has exceeded 8, 16, 24 and 32, two, three four and five WD40 domains are detected for the method.bNumber of domains/proteins with at least 6 WD40 repeats, which use the same rules as WDSP in determining WD domains/proteins.
