Samtools
Setup output directory.
mkdir -p 03_Output/variant_calling/samtools
If you do not have a alignment file in the SAM format you may want to start with Introduction to mapping.
cp 03_Output/mapping/bowtie/REL606.5.sam 03_Output/variant_calling/samtools/
cp 03_Output/mapping/bowtie/REL606.5.fasta 03_Output/variant_calling/samtools/
Prepare reference file.
samtools faidx 03_Output/variant_calling/samtools/REL606.5.fasta
Prepare alignment file.
Convert SAM to BAM format.
samtools view -bS -o 03_Output/variant_calling/samtools/REL606.5.bam 03_Output/mapping/bowtie/REL606.5.sam
[samopen] SAM header is present: 1 sequences.
Variant call output.
