Process the multiple sequence alignment files, the results can be used for the other functional functions. Note that the reference sequence should be included as the first sequence.

a character string specifying the format of the file: "clustal","fasta","mase","phylip","msf", refer to read.alignment function in seqinr package for details.
A vector of sequences with names is returned.
To ensure an exact result, the reference sequence should be included in the alignment as the first sequence.
