| + | The -rst 0 parameter (repeat score threshold) says that a read should be labeled uniquely mapped if its best hit scores >0 more than the next best (the default value is 12, which means that a lot of hits get labeled as repeats, even though they can distinguish between similar repeat regions). | ||

| Note: earlier versions of Newbler provided serially numbered contigs, but version 2.3 seems to skip numbers rather arbitrarily, so that the range of the numbers is larger than the size of the set of contigs. Look at the counts (in assembly/454NewblerMetrics.txt) or run a program to count the contigs, rather than relying on the largest contig number. | Note: earlier versions of Newbler provided serially numbered contigs, but version 2.3 seems to skip numbers rather arbitrarily, so that the range of the numbers is larger than the size of the set of contigs.
