Comment: C: How does Base Call casing affect BWA
... As an update, I've run the random-cased fastqs alignment with our reference modified to not include masking (i.e. I capitalized all lower-case bases), and I'm getting equivalent results as I did when I ran alignment of the fastqs with the reference with masking.

Comment: C: How does Base Call casing affect BWA
... That's interesting -- but the ordering of the reads isn't changing in each run (only casing), so I don't know if the first link applies. We are using a reference that has masked bases though. ...

samtools mpileup -l gives the wrong REF base for some positions
... When I use Samtools (v1.7 or v.1.10) mpileup with -l option to specify the positions I want, many REF bases are incorrect. When I use the -r command (in addition to -l), however, I get the correct bases. For instance, I use these two commands to test consistency between using the -l vs -r options ...
