CONCATENATING sample files to prepare for multiple sequence alignment in Galaxy

These are a few sample files to practice the correct way to concatenate files with the reference strain at the top, in order to continue with the next step, which is doing a multiple sequence alignment.

本数据集提供若干示例文件，用于练习文件的规范拼接操作，要求将参考菌株置于拼接后文件的首位，以顺利推进后续的多序列比对流程。
