                     This does not work at all for us. Many dbkeys lengths simply have too many contigs that are completely irrelevant for 99% of plotting operations. Our options were:

                     - picking for the user (will never be right)
                     - picking some N contigs (also never right)
                     - regex (eww, and requires users to know thje names of things in the data table which is not exposed to user ever.)
                     - built in custom filters we'd have to maintain
                     - some code files (see meme_chip.xml, doesn't work there.)

                     - using one of the legacy chromosomes that doesn't include detritus

                     But none of the optinos work well or uniformly, so, no. We're forced to remove this as an option completely.

   Made a nice plot? Share it with us in the `training materials <https://github.com/galaxyproject/training-material/issues/1867>`__, we're looking for more cool plots with scientifically relevant stories to share with the students who want to learn how to use Circos.

   No data or plot crashes? Check that your chromosome naming scheme matches between your Karyotype file and your datasets.

Circos is a software package for visualizing data and information. It visualizes data in a circular layout — this makes Circos ideal for exploring relationships between objects or positions. There are other reasons why a circular layout is advantageous, not the least being the fact that it is attractive.

Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience.
