This command calculates principal components clustering for the input matrix of pairwise distances. This matrix must be in the PHYLIP format and can be produced by the Alignment.id_table(), Alignment.compare_sequences(), or Alignment.compare_structures() commands.
The projected coordinates and are written to file file. The output file can be used with ASGL to produce a principal components plot.
This command is useful for deciding about which known 3D structures are to be used as templates for comparative modeling.
Example: See Alignment.id_table() command.
