bwa pipe

'bwa mem /data1/ref/Gmax_275_v2.0.fa '+sys.argv[1]+' '+sys.argv[2]+'| samtools view -bS - > '+sys.argv[3]

bowtie2 pipe

1. Make bowtie index

bowtie2-build reference.fa reference.fa

2. Align

bowtie2-align -p num_threads -x reference_index -1 paired_1 -2 paired_2 -S sam_output

3. convert sam to bam

samtools view -Sb <SAMFILE> > <BAMFILE>

variation discovery

4. sort bam

5. bam index, fasta index

6. samtools mpileup -DSug <bam1> <bam2> .... -f reference.fa(fasta indexed) | bcftools view -vcg -

<changed version, samtools mpileup -f scaffolds.fa -v -t DP,AD,ADF,ADR,SP,INFO/AD,INFO/ADF,INFO/ADR -u -b bam_list | bcftools call -v -m -O v > variant.vcf>

Insert size estimation

samtools view /alima9002/denovo/with_Gmax_275/CS-12/CS-12_Gmax_275.bam.sorted.bam | awk '{if ($9 > 0) {print $9}}' > /alima9002/denovo/with_Gmax_275/CS-12/CS-12_Gmax_275.bam.sorted.bam.insert.size

get median or get mode
