RNA-Seq best practice workflow STAR 2-pass mapping question

thkitapcithkitapci Los AngelesMember

I want to use RNA-seq best practice workflow (https://software.broadinstitute.org/gatk/documentation/article.php?id=3891)

I have a couple of questions:

1) This workflow was last updated on 2017 is this still the current suggested workflow ?

2) I have the following software versions installed

The Genome Analysis Toolkit (GATK) v4.1.2.0
HTSJDK Version: 2.19.0
Picard Version: 2.19.0
STAR: 2.7.1a

Are these the right versions for this workflow ?

3) STAR has a parameter called --twopassMode It seems this is not used in the GATK workflow. Do you have any comments on this ? Should I use this mode or just stick to the method described in the workflow ?

Best Regards
Tevfik Hamdi Kitapci
