 # Placing segments on a phylogenetic tree
 
 The next logical step after obtaining the consensus sequences of segments of our sample is to explore how those sequences are related to the sequences in our reference collection.
-To do so, we are going to combine the reference sequences of all segments with their corresponding consensus sequence into one multi-sequence fasta dataset per segment. Then we build a multiple sequence alignment (MSA) from the sequences of each segment, and use these alignments to generate phylogenetic trees, again one per segment. We are going to use two rather standard tools, **MAFFT** and **IQTree**, for generating MSAs and trees, respectively.
