New sequence:
* Solexa 3 lanes;
* 454 shotgun 1/4 Plate (250bp read);
* 454 paired ends 1/4 Plate :
* contain a 44 bp linker in the middle
* the linker sequence is: GTTGGAACCGAAAGGGTTTGAATTCAAACCCTTTCGGTTCCAAC
* there are some (not many) 454 paired end sequences that contain multiple instances of the linker (tandem): Example EUEIEUN01ANUGL_length=128_xy=0154_1891

UNC (e-mail):
* 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,

1. AMOSCmp
454 single reads + Solexa reads /fs/szasmg2/Bacteria/Pseudodomonas_syringae/Assembly/Solexa-454/2007_1009_AMOSCmp-relaxed 142 contigs (37 negative gaps, 89 positive gaps) No read trimming was done. AMOScmp used the following parameters: nucmer -c 20 casm-layout -t 20 -o 5 "-t 20" allows for 20 bp long dirty sequence ends which seem to solve the "low quality" problem. => 22 large contigs 454 single reads + 30 bp Solexa reads => 167 contigs , 49 negative gaps, 100 positive gaps 454 single reads + 25 bp Solexa reads => 293 contigs, 144 negative gaps, 131 positive gaps
2. AMOSCmp
454 single reads + Solexa reads + 454 paired ends Only the 454 paired ends that contain 1 single complete adaptor sequence were used (allmost all) /fs/szasmg2/Bacteria/Pseudodomonas_syringae/Assembly/Solexa-454-454p/2007_1011_AMOSCmp-relaxed-filtered 149 contigs; very similar to the prev ome
3. AMOSCmp (MAJORITY=50)
454 single reads + Solexa reads /fs/szasmg2/Bacteria/Pseudodomonas_syringae/Assembly/Solexa-454/2007_1015_AMOSCmp-relaxed-MAJORITY50 131 contigs (18 negative gaps) No read trimming was done. AMOScmp used the following parameters: nucmer -c 20 casm-layout -t 20 -o 5 -m 50 No read trimming was done. "-t 20" allows for 20 bp long dirty sequence ends which seem to solve the "low quality" problem. "-m 20" merges some contigs together => 10 large contigs

6. AMOSCmp (Chromosome+3 plasmids ref)
Sanger reads Reference=complete genome(chromosome+3 plasmids) use "circular contig" in Celera 3.11 assembly /fs/szasmg2/Bacteria/Pseudodomonas_syringae/Assembly/Sanger/2007_1012_AMOSCmp-relaxed-3plasmids 38 contigs: 15 for main chromosome, 1 for longer plasmid, 21 for shorter plasmid, 1 for "circular contig" The missoriented read pile corresponding to the chromosome (4. AMOSCmp of Sanger reads) has dissapeared AA ready for submission: /fs/szasmg2/Bacteria/Pseudodomonas_syringae/Assembly/Sanger/2007_1012_AMOSCmp-relaxed-3plasmids/AA/umd-20071030-141700.tar.gz
