General cases of Ploidy and Alleles
I am trying to make vt handle [,_Alleles_and_Genotypes general cases of ploidy and alleles].
Please let me know if that is lacking in a tool that you are using.
== BCF Compression vs Compression Time ==
The zlib deflation algorithm (a variant of LZ77) has 10 levels - 0 to 9. 0 has no compression but instead wraps up the file in zlib or bgzf blocks.
Levels 1-9 denote an increasing compression level in exchange for longer times for compression.
In general, zlib compression does not have significant difference in compression between the 9 compression levels as shown in the following table:
{| class="wikitable"
! scope="col"| Compression Level
! scope="col"| Size
! scope="col"| Time
|0 <br>
1 <br>
6 (default)
| 153GB <br>
99GB <br>
| 25m<br>
