... I can understand why you say yours is a paradigm shift: optional columns unify multiple formats, but optional tags don't.

... My understanding is that to an alignment format, you still propose to have fixed columns and optional columns. The major difference from SAM would be that each line ought to have a fixed number of optional columns, as are defined in the header. This could work, but I am not sure how much it improves ...

... I always think the biggest mistake in SAM (not BAM) is the integer flag because it is not human readable. I proposed letter flags, using one letter for one flag bit, but the proposal fell through. Probably I should have acted more firmly at the time. On the other hand, I am not sure how binary flag ...

... Another major problem with the current long-read technologies is that they are unable to call SNPs from diploid genomes. In theory, PacBio probably can achieve the goal, but no available tools match the accuracy of Illumina data yet. Nanopore can't so far, even in theory. Without solving this proble ...

... In somatic mutation calling, multiple SNVs on one read are mostly false positives even if you see no evidence in the paired normal. I am not sure what is the exact cause, but most SNVs like these don't get validated experimentally. ...

... Most biologists don't run VM, let alone install a Linux in it. Your tool should simplify data processing, not complicate it. I don't know what industrial users will think about the tool, but I am moderately certain that few academia users will use it.
The dependencies you chose are too heavy. I don ...
