hoffmann.bioinf.uni-leipzig.de - segemehl is a software to map short sequencer reads to reference genomes. Unlike other methods, segemehl is able to detect not only mismatches but also insertions and deletions. Furthermore, segemehl is not limited to a specific read length and is...
apps.bioconnector.virginia.edu - Coverage / Read Count Calculator
Calculate how much sequencing you need to hit a target depth of coverage (or vice versa).
Instructions: set the read length/configuration and genome size, then select what you want to calculate.
