asm_flags
This indicator decides in which part(s) the reads are used. It takes value
1(only contig assembly), 2 (only scaffold assembly), 3(both contig and scaffold
assembly), or 4 (only gap closure).

rank
It takes integer values and decides in which order the reads are used for
scaffold assembly. Libraries with the same "rank" are used at the
same time during scaffold assembly.
