Hi,
I have a problem and I can't find a solution to it anywhere.
In hawkeye (assembly visualisation sofware of Amos), we can see a graphic of "coverage stat" that correspond to the A-statistic parameter. I want to calculate this statistic in all points of the contig like in this softwtare.
I finded a PDF in internet that explaine how to calculate it:
A-statistic : Model the "arrival" of reads along the length of a unitig as a Poisson process:
G: length of genome
N: total number of reads
k: number of reads in the unitig
D : the distance between the start of the first read to the start of the
kth read
A-statistic = DN/G log (e) - k log (2)
Anyway, I can't applicate it in differents points of contig so that I can create a graphic.
Somebody can give me some explination or example to calculate it?
Thank you very much
