**What it does**

Given a barcode freqeuncy table or an MTX-format matrix from which one can be calculated, produces a barcode rank plot to assess distinctness of droplets with cells over those without (a key mark of good-quality droplet single-cell RNA-seq data).

Thresholds are calculated and plotted, either with DropletUtils or by custom method discussed at https://github.com/COMBINE-lab/salmon/issues/362#issuecomment-490160480.

**Inputs**

    * two-column tab-delimted text file with barcode frequencies OR an MTX-format matrix file

-----

**Outputs**

    * PNG-format plot file.
