Combined alignment for each protein with data from all hosts and subtypes

Multiple alignments for all the protein. Each file has sequences coming from both human and avian hosts and both subtypes H1N1 and H3N2. All the sequences were obtained from the NCBI database. They were used to infer phylogenies (Figure 4 and additional file 6 in the paper).本数据集包含针对所有蛋白质的多重序列比对（multiple alignments）。每份文件均包含源自人类与禽类宿主，且涵盖H1N1、H3N2两种亚型的序列。所有序列均取自NCBI数据库。上述序列被用于推断系统发育树，对应论文中的图4与补充文件6。
