Alignment Output

The visualisation of alignments generated by FLAK can be outputted in either graphical or text formats:
  • Graphical: Selecting the Save Synteny Plot (Flak 1.0 - Ultra-fast Fuzzy Whole-genome Alignment) button on the plotter window toolbar enables the alignment visualisation to be saved as a PNG file. The dimensions of the PNG image will match the zoom level in the plotter window.

  • Text Output The set of alignment positions in the query and reference genomes, along with the length of each alignment, can be outputted by selecting the Save Alignment Data (Flak 1.0 - Ultra-fast Fuzzy Whole-genome Alignment) button on the plotter window toolbar. The file name and sort order can then be specified in the Save Alignments dialogue:

    Save Alignments

    Note that the alignment positions written to file will reflect the current state of the genome alignment visualised in the plotter window, i.e. fuzzy options (hedges and fuzzy logic) or filters applied to the visualisation will also be applied to the output.


Output Format

The header portion of the file provides a summary of the query parameters used in the comparison, including time, the length of the query and reference sequences, the seed pattern, β cut-off threshold and minimum match length. The body of the file contains the outputted alignment data in a tab-delimited format, using the field order: Query From, Query To, Reference From, ReferenceTo and Length. Reverse complement matches are highlighted by a trailing triplet of asterisks (***). As the alignment data outputted matches the visualised data in the plotter window, FLAK allows users to perform some post hoc experimentation on a genome comparison.
