I am not willing to discuss the details on a public forum, especially because my work is unpublished
I probably wouldn't understand the hardcore genomics anyway :)
But ... if you could isolate the differences in non-genomic terms. Eg. The results are more random; or less random; or way too random?
Or if you are want to discuss it off-line ...
I am posting about here in this threads, is related to our previous discussion thread on shuffling DNA and using that to estimate False Discovery Rates of a certain type of "feature" in the genome
I thought the processing was familiar :)
One question. Why are you shuffling the data 10 times? Is this your innovation; or part of some procedure described somewhere that you are following?
The reason I ask is: it shouldn't be necessary. Actually, I'll re-state that. It isn't necessary!
The whole point about the Fischer-Yates shuffle is that every possible reordering of the data is possible; and they all have equal probability.
Thus; by shuffling multiple times all you are doing is choosing a different mix. Not a better one; nor a more random one; just a different one.
And that could just as equally be achieved by seeding the PRNG differently: srand( time * rand() ) or similar.
But as all outcomes are possible from every shuffle -- including the first one -- doing multiple shuffles is just wasting time; nothing more.
