**Hello everyone, I've been trying to generate vcf files for my samples. I did a single sample as a start just to see if everything is going well. could you please take a look at the output and let me know if you see anything strange? (I'm a beginner and this my first time generating a vcf file) Is it normal that the quality score is the same for all sites? This is the output of command:
head -n 50 1_16_variants.vcf
