Last year I posted about the Lander-Waterman equation used to calculate the number of reads needed to sequence a sample. I explained that this general equation (C = LN/G) can be rearranged to allow you to compute the number of reads (N) to sequence a genome of known size (G) with specific coverage (C) and using reads of a specified length (L). Today I finally finished my Calculoid NGS reads calculator to make it easier to access..feel free to use and reuse as you see fit.
