... The SVanalyzer `SVcomp` tool does take repeat homology into account since it constructs the resulting haplotypes and compares them. I haven't tried it myself yet, so am not sure whether it also works with non-sequence-resolved calls though. ...

... Comparing SVs across callers is certainly not an easy problem. There is active work in the GIAB consortium around deriving high quality SV call sets and developing tools for comparing call sets, so there are several options under current development. You will probably end up trying a few tools to se ...

Comment:
C: MAF vs VAF
... Yes, and I would favour the term Variant Allele Fraction (or Variant Allelic Fraction) rather than Variant Allele Frequency for this reason too! ...

... It's worth noting that assuming hom-ref if coverage exceeds some threshold is a reasonable heuristic in most cases, the real situations can be more subtle. For example, the alignments at a site may have predominantly low MAPQ, or alternatively the alignments may contain enough mismatches that a conf ...

... Normalization such as left-aligning indels can help for simple cases, but these are not the state of the art for VCF comparison. This is a clear case where you should be using a haplotype-aware VCF comparison tool. As well as being able to deal with situations where an indel is placed at a different ...

Comment:
C: VCF Normalisation is required ?
... Both hap.py and vcfeval perform comparison at the level of underlying haplotypes asserted by the entries in the VCF, so they don't require up-front normalization. Normalization is mostly useful if you are trying to do comparisons using tools that don't operate at the haplotype level (but such tools ...

C: SMaSH installation error

... You might like to try the `rtg somatic` command from [RTG Core][1]. It uses a Bayesian model to jointly call the normal and tumor, including options to output both germline variants as well as gain-of-reference (potential somatic reversion) calls. As well as the primary score fields produced by the ...

... Decompressing and recompressing with gzip is slow as it is typically limited to one core (although see `pigz` and `pbgzip`). If the VCF were block compressed it would technically be possible to decompress just the block(s) containing the VCF header, write it out with the edited header, and then dire ...
