Data Issues

  • Problems if the coverage > read length; solution: sample the reads
  • Analyze the data before assemble it:
    • If there is a reference genome map the reads to it
    • Plot kmer frequencies (use multiple kmer sizes) ; see how they compare with the estimated coverage

Sourceforge

  • Constants:
 cat src/AS_global.h
 ...
 #define AS_READ_MIN_LEN                   64  # should decrease for short Illumina reads  32 ???
 #define AS_OVERLAP_MIN_LEN                40  # should decrease for short Illumina reads  30 ???  

 #define AS_READ_MAX_PACKED_LEN            104  # max Illumina read length; incread to 124
 
 #define AS_READ_MAX_NORMAL_LEN_BITS       11   # should be increased to 12+ if there are many frequent kmesra nd dpn't fit in the hash

cat src/AS_CGW/AS_CGW_dataTypes.h
#define CGW_MIN_DISCRIMINATOR_UNIQUE_LENGTH 1000   # should be decraesed for short reads assemblies ; all unitigs less than that do not get scaffolded

  • Sanger
 runCA -d . -p prefix -s spec Sanger.frg
  • doOverlapTrimming=1 (default)
  • low qual Sanger reads (ex: 20 or 'D') are discarded
  • Illumina reads are trimmed at 5'/3' (bp with qual < 5 (E) are deleted; read is deleted if new length< 64)
  • astatLowBound 1 (default)  ; can be lowered for low/un-uniform coverage
  • astatHighBound 5 (default)
  • computeInsertSize=0 (default)
  • 454 & Hybrid : convert sff to frg
 sffToCA -libraryname 454 -output 454 454.sff
 runCA -d . ovlOverlapper=mer unitigger=bog -p prefix *.frg
 runCA -d . -s ~/bin/runCA.454.spec -p prefix *.frg
  • gatekeeper -L : search for 454 paired end linker
  • AS_GKP_sff.c  : Load_SFF function
  • for mated libs set mean=3000,stdev=300

Gatekeeper

Build

  • Create & add
 gatekeeper    -o prefix.gkpStore -T -F prefix*frg
 gatekeeper -a -o prefix.gkpStore -T -F prefix*frg

Update

  • edit frg: act:R !!!
 {DST
 act:R
 acc:10691
 mea:161662
 std:28760
 }
  • append
 gatekeeper -a -o prefix.gkpStore -T -F edit.frg
  • Using tab file
 Example: No restrictions on lib stddev with --edit option

 cat prefix.update
 lib     uid     19070   mean    167001
 lib     uid     19070   stddev  167001
 lib     uid     19070   isNotRandom     1
 lib     uid     19070   Orientation     O            # outie orientation for Illimina libs >1K
    
 gatekeeper --edit prefix.update prefix.gkpStore
  • Update read CLR/CLV
 gatekeeper -a -r prefix.clr -o prefix.gkpStore   # not in the wgs release
 gatekeeper -a -v prefix.clv -o prefix.gkpStore

Delete

  • DST messages can not be deleted
  • A FRG can be deleted only if there is no related LKG message; an abbreviated MSG

  • Illumina note:
 We recommend removing reads that do not pass the GA analysis software Failed_Chastity fi lter before attempting to assemble the sequence.
 The chastity of a base call is the ratio of the intensity of the greatest signal divided by the sum of the two greatest signals. 
 Reads do not pass the quality fi lter if there are two or more base calls with chastity of less than 0.6 in the fi rst 25 cycles. 
 These reads have an “N” in the last column of the GA analysis software export file.

 Removed all reads that contained ambiguous characters (Ns).
 Removed reads that did not contain at least 25 Q30 bases among the first 35 cycles (s35).

CAUG notes

Illimina mates

  • short: innies PE (paired ends)
  • long: outies MP (mate pairs) "lots of issues" (eg> : linker is one bp; solution : take 36bp from each end of the read to amke sure you don't get the linker
  • wgs 6.1 : Illumina limit of 104 bp; can recompile the code o make it 232
