Occurrence times for residues that flank known ligand-binding aromatic residues.

The occurrence times were derived from the two upstream and downstream residues flanking 97 known aromatic ligand-binding residues and were transformed into weighted scores for HAR prediction.出现频次提取自侧翼紧邻97个已知芳香族配体结合残基的上下游各两个残基，并被转换为用于HAR预测的加权得分。
