Map integer (red, green, blue) tuple to a ReportLab Color object. Individual hits are coloured in a graduated scheme from dark red to light blue in order of decreasing sequence similarity. Sure, you can use fasta files to draw genome diagrams; you could provide the features you want to draw on top of the sequence from other files (say a gff file or a simple table you might have). x - a float (0->1), the proportion of the page to take Circular diagram rendered by GenomeDiagram of the reciprocal best hit comparison of all coding sequences from Eca against 229 bacterial genomes. Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience.
