Description Usage Details Value Note Author(s) References See Also Examples

The triplex.group.table function returns default isogroup tables for parallel and antiparallel triplex types.

1	triplex.group.table()

This function is used by triplex.search function to get default isogroup tables. These tables correspond exactly with Table 1 published in (Lexa, 2011) and they represent the isomorphic groups of triplets.

As a common triplet structure is H.WC:WC, to customize isogroup tables just use H as a row index, WC as a column index, then set desired group number and pass such modified tables through group_table option of triplex.search interface.

List of two matrixes, one for parallel triplex types and the other one for antiparallel.

If you modify the isogroup tables, you should consider changing also default P-value constants (lambda, mu and rn), because these are valid just for the default isogroup tables.
