Comparing multiple samples using the same color representation of blobs #75

Closed Jigyasa3 closed 6 years ago

Jigyasa3 commented 6 years ago

Hello

Is it possible to use the same key or color representation of blobs for different samples? When I run blobtools plot command it generates the gc-cov plot but assigns different colors to same taxonomically classified contig. For example, E.coli in one sample is represented by blue whereas in other sample by red. There is a --color option, but could you explain the file format for it?

Hi Jigyasa3,

If you look in the examples folder the is a colours.txt CSV file in the right format, which can be used with the --colour flag.

It is essentially composed of two fields (name of the taxonomic group and HEX colour), separated by commas, i.e.:

Nematoda,#48a365
Tardigrada,#48a365
Actinobacteria,#926eb3
other,#ffffff

In order to use the automatically generated colours by blobtools you can consult the *.stats.txt file generated when making a blobplot. There the different taxonomic groups are listed together with metrics including the HEX colour they were assigned in the blobplot.

Hope that helps,

cheers,
