The pairwise distance
WebbThe matrices represent the pairwise distance between the parametric vectors defining the 719 models. Insets show the histogram of the values in the distance matrix. Source publication... WebbFirst, a pairwise distance matrix for all the sequences to be aligned is generated, and a guide tree is created using the neighbor-joining algorithm. Then, each of the most closely related pairs of sequences are aligned to each other. Next, each new alignment is analyzed to build a sequence profile.

Once the closest neighbors are identified, the algorithm consolidates them into a new node, effectively reforming the star tree. This process is repeated until all sequences are connected in a fully resolved tree. 2.
