残基性质比对上色以FASTA或者GCG格式的比对序列作为input，并对比对结果进行上色。该程序会对每一个残基进行检查，并和相同列的其他残基进行比较，如果残基相同或者相似，那么给以彩色的背景，颜色的选择与残基的性质有关。

粘贴FASTA或者GCG格式的序列比对结果，最大输入为2万字符。

• 每行显示 30 40 50 60 70 80 90 100 200 300 个残基
• Percentage of sequences that must agree for identity or similarity coloring to be added: 10 20 30 40 50 60 70 80 90 100
• Used colored backgrounds text .

Enter the starting positions of the sequences separated by commas (to alter residue numbering). An example entry is:

0, 200, 0, -1. If no numbers are given, the default starting position of 0 is used for each sequence.
