When I was using the Polarity-Index method a few days ago, I noticed differences in Table 3, as published.

However, it should be as in Table 3.

Table 3: Number of matches in a typical SCAAP sequence in each peptide database with single or multiple action on fungi, viruses, mammalian cells, Gram+/Gram− bacteria, cancer cells, insects, parasites, and sperms (see also Section 2.6) [7].

These changes do not affect neither the efficiency of the method nor any section of the paper.

I also noted the difficulty to compare information on the same APD2 database (November 2011), as it changes weekly. Therefore I am sending a file to support that test, in case the journal has backup for additional information. Otherwise I will to keep this information for three years.
