mutation pictures of coronaviruses,
409 selected viruses from genbank,Dec.2019, close to SARS/nCoV
the ~30000 nucleotides were divided into areas of 3000
so they fit on one page
using my old program designed for influenza (which has segments of <2300 nucleotides)
each black pixel is a nucleotide different from the average at that position
each line is a virus, each column is a position
positions without mutation are left out
rows and columns are re-sorted for maximum connected areas of black pixels
the average = orange rows are mainly human SARS-viruses
(I should remove them and run it again ...)
