  "-t 20" allows for 20 bp long  dirty sequence ends which seem to solve the "low quality" problem.

 * Theoretical minimum number of contigs we can obtain is 268 (our reads fail to cover 269 nucleotides). 
 * Our de novo assembly spans the genome in 853 contigs totaling 6,313,026 bp. 
 * 98.7% of the genome is covered by a contig; 
 * 84% of the genome is covered by contigs 10,000 bp or greater. 
 * The average gap size between contigs is 98 bp; 
 * average contig size 7401 bp. 
 * The N50 = 37,444 bp. 
 * Our largest BAMBUS "scaffold" is 2,565,761 bp

Solexa assembled at different read coverages

 Location: /fs/szasmg2/Bacteria/Pseudomonas_syringae/Assembly/Solexa/sample/
 
 Several assemblies, using 10%,20%, ... 100%, of the P. syringae Solexa reads. 
 These would correspond to 3X,6X ... 30X coverage 
 The read sampling was done randomly. One sample set for each coverage.
