Hi Wade,
I'll send you the package off-list. And discuss how we can do for the data as it's still interesting for me to enhance my chromosome name validity checks.
Cheers,
Nico

If you're not familiar with that, I could send you a windows zip archive of the package, just let me know.

But I have been learning over the past month how to deal with raw NGS for the first time, and the number of different ways and packages is a bit overwhelming. Fortunately, I discovered your package, and it has simplified things greatly and helped me understand the workflow better to getting to a count table. So once again, thank you! I am sure you will have many users in the coming months.
