These are both works in progress! But here is the first one for working with sequencing data:

And the second:

The second one has a really useful utility called "stack" that you can use to concatenate datasets where one might lack some columns or the columns come in a different order. It glues it all together and has an option to include the filename. It's useful for data analysis.

Both of these lack 'polish' at this point but a few of the subcommands work quite well.
