GC overhead error [java.lang.OutOfMemoryError] while running snpEFF version 4.1

Question

[halo22]

Hello All,

I am trying to run SnpEff on a multisample VCF file, the program processes variants until chr-5 and then dies with the following error. I'd really appreciate if you could help me with this. NOTE: I have added '-c snpEff.config" because I have edited the config file for the download and install of the reference database GRCh38.

The following is the command that I am running:

  Command: snpEff -c snpEff.config GRCh38.86 myInput.vcf.gz -v -stats Annotation.html  >  Annotated.ann.vcf
