WebMap the reads back to the longest assembled sequence using bwa mem and calculate the read depths for each position in order to determine the nuclear depth threshold (ND threshold). Count kmers of size 31 in all reads and only keep a subset of reads that contains at least one 31-kmer with a frequency that is greater than the ND threshold.

WebSpecifically -q and -Q options have their meanings swapped between "depth" and "mpileup". o The removal of overlapping sequences (option -s) is on by default in "mpileup" and off by default in "depth". Additionally the overlap removal algorithm differs, giving subtle changes when Ns are present in the sequence. WebUsing the -d option, bedtools genomecov will compute the depth of feature coverage for each base on each chromosome in genome file provided.
