Running filtering without .pstats file

[MartinLoza]

Hi, thank you for coding and maintaining such a useful tool!
I have a couple of "pairs" data from a collaborator. As we don't know if the pairs were already quality-checked, I would like to use the filtering function before binning.
However, it looks like the function requires a ".pstats" file. This file is usually obtained if you perform the complete pre-processing, but in this case, we don't have it. I was wondering if there is a way to generate this file from my .pairs file or create a dummy one (empty file didn't work).

Again, thank you for this great tool, and for taking your time to maintain it!
