Thus, paleopolyploidy is identified as a "peak" on the duplicate number vs. Ks graph (shown on the right). However, using Ks plots to identify and document ancient polyploid events can be problematic, as the method fails to identify genome duplications that were followed by massive gene elimination and genome refinement.
Like strict phylip format files, relaxed phylip format files can be in interleaved format and include spaces and endlines within the sequence data. The programs that use distance data, like the neighbor program that implements the neighbor-joining method, also use a simple distance matrix format the includes only the number of taxa, their names ...
Row echelon form — a matrix in this form is the result of applying the forward elimination procedure to a matrix (as used in Gaussian elimination). Wronskian — the determinant of a matrix of functions and their derivatives such that row n is the (n−1) th derivative of row one.
Weaknesses of doing an ACH matrix include: The process to create an ACH is time-consuming. The ACH matrix can be problematic when analyzing a complex project. It can be cumbersome for an analyst to manage a large database with multiple pieces of evidence. Evidence also presents a problem if it is unreliable.

If Gaussian elimination applied to a square matrix A produces a row echelon matrix B, let d be the product of the scalars by which the determinant has been multiplied, using the above rules. Then the determinant of A is the quotient by d of the product of the elements of the diagonal of B : det ( A ) = ∏ diag ( B ) d . {\displaystyle \det ...
