 +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. ​ Look at the counts (in assembly/​454NewblerMetrics.txt) or run a program to count the contigs, rather than relying on the largest contig number.

 +For large genomes you can pass the -large argument to runProject and it will take some time-saving shortcuts.
