PSORTb v. 2.0 Performance

PSORTb version 2.0 displays the highest precision of any bacterial protein localization prediction tool available, with an overall precision of 96%. The program displays an overall recall of approximately 82%, and is comparable to other current tools in the number of predictions it is able to generate.

Precision (TP/TP+FP) and Recall (TP/TP+FN) values for PSORTb v.2.0 are shown below - Table 1 displays P and R values for proteins with a single localization site, Table 2 displays P and R values for proteins with multiple localizations. Table 3 displays P and R values of PSORTb compared to other available localization prediction methods.

Details on our performance analysis can be found in the PSORTb v.2.0 manuscript. The confusion matrices with the raw output from our performance analysis can be found at the PSORTb v.2.0 Supplementary Information page.
