  1. Minimus ran faster than phrap and produced no errors. However, it generated a considerably larger number of contigs. Note that the table contains two quantities denoted "coverage": the sequencing coverage (reported in the #Reads/seq. coverage column) represents the total amount of DNA in the sequenced reads, divided by the size of the chromosome, i.e. the redundancy in the sequenced data; the column headed "coverage" represents the fraction of the reference sequence covered by assembled contig. The latter measure does not take into account assembly errors, i.e. partial contig matches contribute to the overall coverage.
