test accuracy from scanprosite

http://www.cs.nyu.edu/~ysc212/bioinfo/scop/scoptest/scoptest2.html
copy paste scanprosite's search result into second box,
it will tell you what's the true positive and false positive.

about false positive and true negative, you should done that when you use scanprosite, not here.
hint: provide true positive pdb code as testing set (Protein(s) to be scanned) on scanprosite, then you can know the true positive rate and false positive rate.
