The symbol frequencies counted in all proteins.
Example: Assume that you provided 2 protein sequence sets. Then this first example line means that in the first protein of the set A the amino acid Y (tyrosine) occurs with a frequency of 0.016 i.e. 1.6% of all resuides in this protein are tyrosines (5% would be expected if all amino acids would be equally used.)
DATASET | AA | FREQ |
setA | Y | 0.016 |
Description of set A: | '$SETA' |
Description of set B: | '$SETB' |
