This may be a simple question.. (genome coverage)

[Shrub]

W = NI/G

Where W = coverage, N = total number of clones in the library, I = mean length in base pairs of DNA inserts, and G = the 1C genome size (in base pairs) of the organism from which the library was made.

Would N be the # of colonies or will I need further calculations and why?

[a_mt]

in simple terms: coverage=(no. of reads * read_length)/genome_size
