Error when running gridss_somatic_filter

[kcleal]

Hi,

Ive run in to an error running the somatic filter:

Rscript ./GRIDSS/gridss_somatic_filter --input ERR2752450.gridss.vcf --output gridss_hq_somatic.vcf.gz --scriptdir ./GRIDSS/
No reference genome supplied using --ref. Not performing variant equivalence checks.

Any ideas about how to fix this, thanks?

The script only supports gridss vcfs. These vcfs have one ALT allele per record.

Alternatively, it could be a R/bioconductor version issue on your environment.

Thanks @d-cameron for the quick reply. The vcf was generated by gridss. I will make a new environment and try re-installing, thanks!

Hello, I produced tumor/normal vcfs with gridss and would now like to postprocess with 'gridss_somatic_filter'. I ran into the exact issue/error as above and would need advise what to try next. Any help is greatly appreciated!

Details: It is a brand new gridss conda environment, installed with 'mamba create -n gridss gridss' This is my command: 'gridss_somatic_filter --input tumor_vs_normal_all_calls.vcf --output test -n 1 --pondir pondir --ref BSgenome.xxx.yyy.zzz -f test-full' I produced the necessary files (gridss_pon_breakpoint.bedpe, gridss_pon_single_breakend.bed) as instructed and provide them in 'pondir'. I am working in a plant and had to build the BSgenomes package myself. I tried to build it with R-library BSgenome version 1.68 in the gridss conda environment, but it fails to build with this error:

... Error in .TwoBits_export(mapply(.DNAString_to_twoBit, object, seqnames), : UCSC library operation failed (very similar error when 'ondisk_seq_format: fa')

It builds fine with Biocoductor BSgenome library version 1.70 on my system R 4.3, and I am using this BSgenomes package (BSgenome.xxx.yyy.zzz).

[warthmann]

Update: The bioconductor R-library BSgenome version 1.68 from gridss conda install fails to produce a BSgenome package. It was apparently built (R CMD build) without the --keep-empty-dirs flag, so the necessary directories /inst/extdata/ were missing. Creating them solved the issue. See https://support.bioconductor.org/p/124169/

[warthmann]

and I can confirm that my gridss produced vcf has only one REF and one ALT allele per locus. Example entries. Some do contain ".", though.

Hello,

I have been having the same error as warthmann above. Has there been any solution to this?

[hberger]

A quick fix that worked for me:

• Locate the fie libgridss.R in your conda env folder (e.g. ~/.conda/envs//share/gridss-2.13.2-2)
• Replace line 780 in this file

Original:

  isbp = str_detect(VariantAnnotation::fixed(vcf)$ALT, "[\\]\\[]")

New:

  isbp = str_detect(as.character(VariantAnnotation::fixed(vcf)$ALT), "[\\]\\[]")  

Then rerun gridss_somatic_filter.

Note: this assumes that the ALT fields contain a single allele per line, which seems to be the case in my GRIDSS output VCF files.

[warthmann]

Great! thanks @hberger, your fix worked for me as well. I.e., the script now ran through.
