Extract DNA from GenBank Edit

  • Extract DNA from Origin field of GenBank file
for x in *gbk
do
saco_convert -I genbank -O fasta $x > $x.fna
done
  • Rename files from *gbk.fna to *.fna
for x in *gbk.fna
do
newx=`echo $x | sed "s/.gbk.fna/.fna/"`
mv $x $newx
done

16S rRNA analysis Edit

  • Search DNA string for patterns similar to rRNA models in RNAmmer
for x in *fna
do
echo $x
rnammer -S bac -m ssu -f $x.rrna $x
done
  • Count total number of sequences in a set of rrna files:
grep -c ">" *rrna | awk 'BEGIN{FS=":"}{sum += $2}END { print sum}'
  • Rename files from *fna.rrna to *.rrna
for x in *fna.rrna
do
newx=`echo $x | sed "s/.fna.rrna/.rrna/"`
mv $x $newx
done
  • Extract one 16S rRNA sequence from each genome
  • Goes trough each file in the directory called *rrna
select16SrRNA -out all.fna
Selecting the sequence with highest score and length between 1400 and 2000
Default is 1400 - 2000 base pairs, change using -min and -max
Program is writing to file called all.fna
Default output file is selected16SrRNA.fna, change using -out
Number of files to be evaluated (extension *.rrna): 32
Number of files with no sequences: 2
Score: 1920.1 :: Length 1545 :: Acidaminococcus_sp_D21_ID_ACGB00000000.rrna
Score: 1836.1 :: Length 1557 :: Dialister_invisus_DSM_15470_ID_ACIM00000000.rrna
Score: 1878.8 :: Length 1555 :: Dialister_micraerophilus_DSM_19965_ID_AFBB00000000.rrna
Unacceptable length: 1325 :: /molecule=16s_rRNA /score=1197.2 :: Dialister_microaerophilus_UPII_345-E_ID_AENT00000000.rrna
............
  • Using default setting, 6 sequence do not have the right length (1400-1800)
select16SrRNA -out all.fna | grep Unacc | wc = 6
  • Using a smaller minimum length, all 29 genomes have an acceptable 16S rRNA sequence
select16SrRNA -out all.fna -min 1100 | grep -c Unacc = 0
  • Performing a multiple alignment of the selected sequences:
clustalw all.fna
clustalw all.fna -bootstrap=1000
njplot all.phb
  • Save file as post script

Postscript file was made pretty manually in texteditor

Genome atlas Edit

  • Atlases were created for complete genomes= *For each atlas a folder was created to contain the files for that atlas
  • The files are saved but can be deleted as soon as the atlas has been drawn
mkdir GenomeAtlas Vparvula
sed s/XXXX/Veillonella_parvula_DSM_2008_ID_CP001820/g /usr/biotools/genomeAtlas > Vparvula.genomeatlas.sh
chmod +x Vparvula.genomeatlas.sh
./Vparvula.genomeatlas.sh

Identify open readingframes in DNA using Prodigal Edit

for x in *fna
do
prodigalrunner $x
done

Bias in third codon position and Amino acid and codon usage Edit

  • Calculate AT and amino acid usage in open reading frame files, FASTA format

cat $i.atStats.tab > $i.CodonAaUsage
perl /usr/biotools/indirect/CodonAaUsage.pl $i >> $i.CodonAaUsage
rm $i.atStats.tab
done

grep aa *AaUsage > aaUsage.all
sed -i s/_prodigal.orf.fna.CodonAaUsage:aa//g aaUsage.all

grep Total *AaUsage > statistics.all

Drawing heatmaps of Bias in third codon position and Amino acid and codon usage Edit

install.packages("gplots")
library(gplots)
codon <- read.table("codonUsage.all")
colnames(codon) <- c( 'Name', 'codon', 'score', 'count')
codon <- codon[1:3]
test <- reshape(codon, idvar="Name", timevar="codon", direction="wide")
codonMatrix <- data.matrix(test[2:length(test)])
rownames(codonMatrix) <- test$Name
codon_heatmap <- heatmap.2(codonMatrix, scale="none", main="Codon usage", xlab="Codon fraction", ylab="Organism", trace="none", margins=c(8, 25))
dev.print(postscript, "codonUsage.ps", width = 25, height=25)
dev.off()


library(gplots)
aa <- read.table("aaUsage.all")
colnames(aa) <- c( 'Name', 'aa', 'score')
test <- reshape(aa, idvar="Name", timevar="aa", direction="wide")
aaMatrix <- data.matrix(test[2:length(test)])

dev.off()

Bar and rose plots for amino acid, codon usage and bias in third position Edit

for x in *orf.fna
do
basicgenomeanalysis $x /usr/bin/gnuplot
done

BLAST martix Edit

  • Input file is created in directory with protein files in FASTA format
  • Takes all fsa files in directory
makebmdest . > bmdest.xml
blastmatrix -cpu 5 bmdest.xml > blastmatrix.ps

Core and pan genome analysis, single linkage clustering Edit

  • Input file is created in directory with protein files in FASTA format
  • The output is a post script file and a table written to the screen =
ls -1 *orf.fsa | gawk '{print $1 "\t" $1}' > pancore.list
pancoreplot pancore.list

Genome statistics Edit

for x in *orf.fna
do
