In preparation for a paper we're writing, we needed some summary stats on the various genome assembly feature sequences. I determined the max/min, mean, and median sequence lengths for all the GFF feature files we currently have for Pgenerosa_v070, Pgenerosa_v070_top18_scaffolds, and Pgenerosa_v074. This info will be compiled in to a table for the manuscript. See our Genomic Resources wiki for more info on GFFs:

- [Genomic Resources Wiki](https://github.com/RobertsLab/resources/wiki/Genomic-Resources) (GitHub)

Calculations were performed using Python in a Jupyter Notebook.

# RESULTS

I've copied/pasted (and, reordered) the summary data for each of the GFFs that were analyzed, for quick reference. Will get this compiled in to a table of some sort for people to use for the manuscript.
