Hi there, I am having trouble with interpreting bcftools mpileup vcf output. My file has almost all <*> listed for the alternate field.

enter image description here

I am aligning my paired-end reads to an E.coli reference genome. Anyone have any intuition as to why this is happening?

bcftools mpileup must be followed by bcftools call to call the variants. see "Variant calling" in http://www.htslib.org/workflow/

Yep, I performed variant calling on the mpileup. I am just wondering why I have no ALT equal to "." in my vcf file at all. So when I call variants, my vcf file only has a very small number of mutations. I understand that "<*>" is a wild type but I would like to know if any of those could be possible indels.
