Reads used in the assembly:
=== Assembly description ===
* all WGS reads aligned by nucmer (default params: min 65bp, 80%id) to the top 7 Sanger contigs(good) + mates
=> 36767 reads,  17875*2 mated reads


# The Wolbachia pipientis endosymbiont of Culex quinquefasciatus assembly was downloaded from the Sanger web site (July 2007 version: 12 contigs)
# 5 of the 12 contigs were discarded due to their high GC% or repetitive content; 7 contigs were kept to be used for sequence alignments
# The NCBI TA Culex quinquefasciatus traces were downloaded locally (Sept 2007: 7,379,314 total Sanger traces; 7,183,129 WGS)
# The WGS traces were aligned to the 7 reference contigs using nucmer (default parameters: minimum 65bp length, 80% identity)
# The traces that aligned and their mates were filtered out and formatted as input for Celera Assembler (36,767 total traces; 35,750 mated, 1,017 unmated)
# The traces were assembled with CA (wgs-5.1) (default parameters except for unitiggerRrrorRate=2%)
# The assembler generated 16 scaffolds, 21 contigs and 92 degenerates;
# 5 scf, 10 ctg & 11 deg were filtered based on their "uniqueness"; 2 of the scaffolds contain multiple contigs
# There are 2 unique regions in reference not present in this genome  (NC_010981.1: 775928-776047 120bp; 1253284-1254139 856bp)
# There are 4 unique regions (~ 500bp each ) in this genome not present in the reference sequence/assembly:    ctg7180000001230_202_725, ctg7180000001305_11303_11867, ctg7180000001305_13367_14006, deg7180000001252_328_851

2006_1226_WGA

initial assembly

Steps:

 1. All cpqg reads have been downloaded from the TA (July 2006). The reads have been grouped by libraries and the clear range has been computed. There were 6.6M reads in the download compared with 7.3M now.  Unfortunately I've only noticed this difference at the end of my experiment.
 2. The Wolbachia endosymbiont of Culex quinquefasciatus assembly has  been downloaded from the Sanger ftp site ( ftp://ftp.sanger.ac.uk/pub/pathogens/Wolbachia/Wb_Cq.dbs ) ; there are 95 sequences in this file. Most of them are very short. Below are listed the name,length & gc% of the longest 10: 
    name                        length(bp)   gc%
    culex173d08.p1k               1457497    34.17

 3. The cpqg random reads (clr only) have been aligned to symbiont sequences using nucmer (default parameters)
 4.  The nucmer output has been analyzed. It's been noticed that many of the short symbiont sequences (2-3KB in length) have a higher than expected number of alignments. To avoid the repeats I've  elected only  the reads that aligned to the longest 10 symbiont sequences (see above).
 5. A 95% identity and minimum of 400 bp alignment thold has been used to determine the symbiont reads. There were 29,110 unique reads (30,690 reads+mates) selected. Below is a per library breakdown (reads+mates):

 6. The reads have been assembled using the runCA-OBT.pl script (default parameters).  Most of the reads got assembled into 3 large scaffolds. There is mate pair evidence (outie mates) that the largest scaffold is circular. 
 All the scaffolds ens up in surrogates (20-50KB total surrogate length)
 Are there not enough BE to span the unique regions?  
 Cpqg.qc
 scaff_8 Longest scaff
 scaff_9 2nd longest scaff
 scaff_7 3rd longest scaff
 scaff_6 Small scaff that Looks circular
 7. The scaffolds/contigs have been aligned to longest 10 Wolbachia endosymbiont sequences. Most of the long alignments were at over 99% identity. However, several large rearrangements have been noticed.

new assembly

Steps:

 1. All Culex reads have been downloaded from TA . ~1M new reads since 2006_1226
 2. The reads have been aligned to the new reference (exclude mito,repeats) using nucmer (default parameters)
 3. A 95% identity and minimum of 400 bp alignment thold has been used to determine the symbiont reads.  3850 new reads & mates in addition to the previous ones were identified
 4. 33,783 reads have been assembled using the runCA-OBT.pl script (default parameters).  
 Cpqg.qc
 Compared to the initial assembly, many metrics went down (TotalBasesInScaffolds,MaxBasesInScaffolds,MaxContigLength ...)
 TotalSurrogates & SurrogateInstances more than doubled

2007_0802_WGA-0.5E

error rate =0.5 % => more fragmented assembly

2007_0802_WGA-0.5M

genome size=1.5M => more TotalBasesInScaffolds but more unhappy mates

What to do next?

  • use CA 5.1 (latest version)
  • remove 958 cDNA's aligned to culex*
  • increase utg error rate to from 1.5% to 2% (3% gave worse results than 2%)
  • recruite reads that align to contig ends: some ends are repetitive => too many; others no alignments
  • use 2 other complete strains; only 2 new aligned reads were identified
  • AMOScmp new reference => more unhappy mates then before
  • dropping the min Astat from 1 to -1 made some degens into places ctgs; did not improve overall stats
  • separate JCVI & WIBR reads, assemble separately => 5 obvious alignment breaks
  • use only the reads from lib with insert size <=11Kbp => more fragmented
  • use only the reads that aligned to the top2 Sanger ctgs (36606 instead of 36767)

Assembly description

  1. The Wolbachia pipientis endosymbiont of Culex quinquefasciatus assembly was downloaded from the Sanger web site (July 2007 version: 12 contigs)
  2. 5 of the 12 contigs were discarded due to their high GC% or repetitive content; 7 contigs were kept to be used for sequence alignments
  3. The NCBI TA Culex quinquefasciatus traces were downloaded locally (Sept 2007: 7,379,314 total Sanger traces; 7,183,129 WGS)
  4. The WGS traces were aligned to the 7 reference contigs using nucmer (default parameters: minimum 65bp length, 80% identity)
  5. The traces that aligned and their mates were filtered out and formatted as input for Celera Assembler (36,767 total traces; 35,750 mated, 1,017 unmated)
  6. The traces were assembled with CA (wgs-5.1) (default parameters except for unitiggerRrrorRate=2%)
  7. The assembler generated 16 scaffolds, 21 contigs and 92 degenerates;
  8. 5 scf, 10 ctg & 11 deg were filtered based on their "uniqueness"; 2 of the scaffolds contain multiple contigs
  9. There are 2 unique regions in reference not present in this genome (NC_010981.1: 775928-776047 120bp; 1253284-1254139 856bp)
  10. There are 4 unique regions (~ 500bp each ) in this genome not present in the reference sequence/assembly: ctg7180000001230_202_725, ctg7180000001305_11303_11867, ctg7180000001305_13367_14006, deg7180000001252_328_851
  11. 10 large scale rearrangements
