Output processing

Posmap

  • Get posMap files
buildPosMap -o prefix < prefix.asm
  • Get number of reads/ctg or scf (from the pos files)
 cat prefix.posmap.frgctg | count.pl -i 1 > prefix.posmap.ctgfrgcnt
 cat prefix.posmap.frgscf | count.pl -i 1 > prefix.posmap.scffrgcnt
 cat prefix.posmap.ctgscf | count.pl -i 1 > prefix.posmap.scfctgcnt
  • Compute read/mate/ctg cvg (from the pos files)
 posmap2cvg.pl                                  < prefix.posmap.frgscf > prefix.posmap.scffrgcvg
 OLD/posmap2cvg.4.pl -mates prefix.posmap.mates < prefix.posmap.frgscf > prefix.posmap.scfmatecvg
 posmap2cvg.pl                                  < prefix.posmap.ctgscf > prefix.posmap.scfctgcvg
  • Get 0cvg regions
 posmap2cvg.pl -f prefix.posmap.scflen -Max 0 < prefix.posmap.frgscf  # scaff gaps
 posmap2cvg.pl -f prefix.posmap.ctglen -Max 0 < prefix.posmap.frgctg  # surrogates
  • Get links
 ~/bin/scf2scflnk.sh prefix                      
 ~/bin/ctg2ctglnk.sh prefix                      
 ...
  • Add ctg/scf into to the mates fils
 join12.pl prefix.posmap.mates prefix.posmap.frgctg > prefix.posmap.mates2.tmp
 join12.pl prefix.posmap.mates2.tmp prefix.posmap.frgscf > prefix.posmap.mates2
 rm prefix.posmap.mates2.tmp
  • Display graphs
cat prefix.posmap.scf2scflnk | ~/bin/tab2dot.pl | dot -Tpng -o prefix.posmap.scf2scflnk.png
cat prefix.posmap.ctg2ctglnk | ~/bin/tab2dot.pl | dot -Tpng -o prefix.posmap.ctg2ctglnk.png
  • Qc stats based on posmap files
 posmap2qc.pl -ctgscf prefix.posmap.ctgscf > prefix.qc
  • Break scf/ctg pipeline
 ~/bin/breakPosmapKeep.amos
  • Get scaff file
 ~/bin/posmap2scaff.pl prefix.posmap.ctgscf

Fasta

  • Align deg to scaff
 nucmer -mum -l 40 -c 250 scf.fasta deg.fasta  -p scf-deg
 delta-filter -q scf-deg.delta > scf-deg.filter-q.delta
 ~/bin/delta2pairCvg+.pl < scf-deg.filter-q.delta > scf-deg.filter-q.cvg.pairs
 ~/bin/max2.pl -i 4 -j 6 < scf-deg.filter-q.cvg.pairs > scf-deg.filter-q.maxCvg.pairs
 cat scf-deg.filter-q.maxCvg.pairs | p 'print $_ if($F[5]-$F[6]<2000);' > scf-deg.filter-q.variants.pairs
 awk '{print $5,$6}' scf-deg.filter-q.variants.pairs > scf-deg.filter-q.variants.ids
  • Indexing
 # contigs
 ~/bin/formatdb.pl < prefix.ctg.fasta > prefix.ctg.fasta.offset
 ~/bin/fastacmd.pl -o prefix.ctg.fasta.offset -f filter.ctg.ids < prefix.ctg.fasta > filter.ctg.fasta

 # same for scaff, deg ...
  • Contaminant search : nucmer against
 /nfshomes/dpuiu/db/Ecoli.all
 /nfshomes/dpuiu/db/UniVec_Core
 /nfshomes/dpuiu/db/OtherVec

Asm

  • Get output seq
 asmOutputFasta -p prefix < prefix.asm
  • Get output seq clr
 ~/bin/asm2clrs.pl < prefix.asm > < prefix.asm.clr
  • Get new library insert sizes:
 asm2mdi.pl < prefix.asm > prefix.mdi
  • Get surrogate ids
 #most of them have negative aStat's
 $ cat *.asm | grep -B 8 ^sta:S | grep ^acc | perl -ane '/(\d+)/; print "utg".$1,"\n";'

Qc

 caqc.pl -euid  prefix.asm

Scaffolds

  • Get scaff files
 cavalidate -e 10 prefix
 bank2scaff prefix.bnk/ > prefix.scaff

 ~/bin/ca2scaff -i prefix.asm -o prefix.scaff

 cat prefix.scaff | grep "^>" | sed 's/>//' | awk '{print $1,$2}' > prefix.scfctg
 cat prefix.scaff | grep "^>" | sed 's/>//' | awk '{print $1,$3}' > prefix.scflen  
 cat prefix.scaff | grep "^>" | sed 's/>//' | awk '{print $1,$4}' > prefix.scfspan  

 tac prefix.scaff | p '$count=0 if(/^>/); $count++; print $_ if($count>2);' | awk '{print $4}'   # sequence gaps

AGP

 asmToAGP.pl < prefix.asm > prefix.agp
