I have checked the source code of sambamba view in view.d file. And I found that there has some codes:

160 subsampling_seed = unpredictableSeed;
161 subsampling_seed <<= 32;
162 subsampling_seed += unpredictableSeed;

I have some questions:

Does it mean that seed doesn't need to be set?
When I set the seed from 1-100, I found that the kept reads number is very different. Sometimes, the difference is an order of magnitude at 10^6.

Please tell us how to ste the seed number. Thanks.

There is a command line parameter for setting the seed
