I'm interested in detecting driver genes in some cancer biopsies that have been sequenced using hg38 as the reference. I've looked at three programs so far (MutSig2CV, MuSiC and 2020+) and found clear indications that two of these only support hg19 and I have not found an answer in the online documentation for the third (2020+).

Although I am most interested in knowing which software currently supports hg38, I wouldn't mind hearing about planned upgrades and work-arounds.

...but has this not been done already by other groups? Is it for a Masters project or some other form of training?

I would directly contact the authors of these programs in order to find out whether or not they plan to support hg38 / GRCh38 or not.

I'm going to be looking at cancers that haven't been studied so thoroughly.
I've already reached out to either the authors or people involved with maintaining the software I mentioned to ask about work-arounds and planned upgrades - haven't heard back from anyone yet. I thought this issue might have some mass appeal because the programs I mentioned appear to be some of the most popular for doing this type of work and I was surprised to learn they don't support the latest build of the human genome even though it's already more than five years old.

It is a recurring theme in bioinformatics for developers to go 'quiet' and the software to go un-maintained - the reason could be lack of funding and/or the person moved job. Do you actually need these programs? Why not identify driver mutations and genes through a manual data processing pipeline?

I'm the person that developed 20/20+ and I have moved to another lab. I do still maintain the software. But all improvements are done in my spare time without really any recognition for doing so. I would, however, recommend against "manual data processing pipelines" as such ad hoc approaches are why the cancer literature is filled with contradictory (and often wrong) information.

Hey Collin - no worries. I will also go quiet some day when I have moved on from here!

I've been a secret fan of your responsiveness to the BioStars community for a while. I think it's a great service to the bioinformatics community

Regarding your initial question, 20/20+ currently (as of 6/29/2019) does not support hg38, but we hope to implement it soon.

Hello. dNdScv, which I developed, supports GRCh38. Although it uses hg19 by default, the package contains the files and instructions to run GRCh38, as well as functions to run it on any assembly or species. In benchmarking analyses by PCAWG (the ICGC/TCGA pancancer analysis of whole genomes consortium) dNdScv was shown to perform very similarly to MutSigCV in terms of specificity and sensitivity.

http://htmlpreview.github.io/?http://github.com/im3sanger/dndscv/blob/master/vignettes/dNdScv.html http://htmlpreview.github.io/?http://github.com/im3sanger/dndscv/blob/master/vignettes/buildref.html https://www.cell.com/cell/fulltext/S0092-8674(17)31136-4

dNdScv is an R package. To install it you have to use:

library(devtools); install_github("im3sanger/dndscv")

To run driver discovery on GRCh38, you need to download the precomputed database for GRCh38, and then use:

dndsout = dndscv(mutations, refdb="RefCDS_human_GRCh38.p12.rda", cv=NULL)

See the tutorials above for more details if you are interested in the method.

Hi, I'm Collin, one of the first authors on the TCGA PancanAtlas drivers paper. When we benchmarked several methods, MutSigCV did ok, but had several cancer types where the results were flagged as substantial outliers compared to all the other methods. We however did not benchmark your method.

HI,

I am working on something similar, and know 3 farily recent tools that work on hg38.

  1. https://github.com/luisgls/SSB_selection

  2. https://github.com/im3sanger/dndscv (The one Inigo suggested)

  3. http://genetics.bwh.harvard.edu/cbase/downloads.html The third one doesn't really need any specific genome build.

Note: All of these infer selection in cancer genomes, you might have to do a little bit more downstream analysis for cancer drivers. In general all positively selected genes are potential cancer drivers.
