Default BBnorm target depth setting

Hi Thread/Brian,

I ran BBnorm on a pre-BBduk'd pair of reads. I plan to use the normalized reads for assemblers (Velvet or A5, well, A4 in this case).

./ in1=R1_bbduk20.fq in2=R2_bbduk20.fq out1=R1_bbduk20_norm35.fq out2=R2_bbduck20_norm35.fq target=35

the opening dialog states that the target depth is 140 on pass 1, then 35 on pass 2.

Why the two passes?

What are the "error reads/pairs/types"?

Do these normalizations typically help a BBmap (or other) run as well?
