 6) rMATS requires the length of the reads in the sample. This workflow will attempt to estimate the read length based on a polling of reads. If the user wishes to override this value they can set `read_length_median` to their desired read length. Additionally, there is a `rmats_variable_read_length` boolean that users can set if their reads are not uniform in length. This workflow will poll the reads and set that value to true if it observes multiple read lengths. Like read length, user-provided input will override this guess.

 # [Kids First STAR Diploid Beta](docs/STAR_2.7.11b_DIPLOID.md)
 This is an alternative alignment and quantification method currently in beta phase.
 It uses a patient's DNA variant calls to create a "personal genome" for improved alignment.
