gbtools 2.5.2

• New method for generating plot colors for taxonomic marker overlay. Each taxon is now assigned a weight, based on total coverage x length of the contigs belonging to that taxon, and only the highest-weighted taxa are given a color and included in legend. This prevents legend from being cluttered, and user can adjust the cutoff with markCutoff parameter.
• Specific taxa can now be highlighted in plot with highlightTaxon parameter
• Bug fix for temporary file generation in SSU extraction and blob annotation scripts.
