Separate alignments for each protein of subtypes H1N1 and H3N2 and for humans and avians hosts

Multiple alignments of each protein of both the H1N1 and H3N2 subtypes. A separate file for sequences coming from human and avian hosts is present. All the sequences were obtained from the NCBI database. These were used to create phylogenetic trees (Figure 3 and additional file 5 in the paper)H1N1与H3N2两种亚型的各蛋白质均已完成多序列比对（multiple alignments）。针对人类与禽类宿主来源的序列，设有独立的数据文件。所有序列均取自NCBI（美国国家生物技术信息中心，National Center for Biotechnology Information）数据库。该数据集被用于构建系统发育树（phylogenetic trees），对应论文中的图3与补充文件5。
