So I've been using "load-into-counting.py" and "abundance-dist.py" to calculate the abundance distribution of kmers in some gzip files. I found some of results weird and I suspect it might have to do with the files that are gziped. So I made a small test file and it did give different results on the original file and gziped one. The test files are attached and the command I ran and results are as follows:

I would like to use the function ht.consume_fasta in my pipeline(in python) however I work with really big files and they are always in gzip format.

It will be really appreciated if you can make this feature available.
