Alignment files are sorted by Picard. Then I use Samtools mpileup function to create a pileup file of mapped data prepared for DNA methylation–level calculation. The output seems good. But I find it miss some base at start. What about the first five bases ? Why does it start from the sixth base of chrM ?

This is my command : samtools mpileup -f <genome.fa> <read1_val_1.sort.bam> > <read1_val_1.pileup>

Thank you very much !
