Version: 2.1b (2012-04-26).

  • Revision "2.1c" : Maven project (by Louis Letourneau)
  • Revision "2.1c" : Improved Galaxy wrappers (by Peter briggs)
  • Revision "2.1b" : Improved RefSeq parsing
  • Revision "2.1a" : Multi-thread race condition solved.
  • Note If you are using hg19, it is recommended to download the latest database (due to improved RefSeq parsing in 2.1b).
  • Added multi-threaded support (command line option '-t').
  • GenBank support for building databases. See details here.
  • Config file simplified
  • E.Coli database added
  • Galaxy download database option added.
  • Added all ENSEMBL version 66 genomes
  • Database 'download' issue solved. Apparently SourceForge servers were choking on URL that had double slashes, this should not happen. Implemented a workaround.
  • SnpSift GWAS catalog: Annotate using GWAS Catalog.
  • SnpSift: Added 'varType' to annotate variant type (SNP/MNP/INS/DEL), as well as HOM/HET if possible.
  • Faster VCF processing.

Version: 2.0.5 (2011-11-25).

  • Support for RARE amino acids (see details here)
  • Database for Soybean (Glycine max) added

Version: 2.0.5 (2011-11-25).

  • Database download command, e.g. "java -jar snpEff.jar download GRCH37.64"
  • Added all ENSEMBL version 65 genomes
  • RefSeq annotations support added.
  • Rogue transcript filter: By default SnpEff filters out some suspicious transcripts from annotations databases. This should improve false positive rates.
  • Amino acid changes in HGVS style (VCF output)
  • Optimized parsing for VCF files with large number of samples (genotypes).
  • Option to suppress summary calculation ('-noStats'), can speed up processing considerably in cases where VCF files have hundreds or thousands of genotype fields.
  • Option '-onlyCoding' is set to 'auto' to reduce number of false positives (see next).
  • Option '-onlyCoding' can be assigne a value: If value is 'true', report only 'protein_coding' transcripts as protein coding changes. If 'false', report all transcript as if they were conding. Default: Auto, i.e. if transcripts any marked as 'protein_coding' the set it to 'true', if no transcripts are marked as 'protein_coding' then set it to 'false'.
  • Added BED output format. This is usefull to annotate the output of a Chip-Seq experiment (e.g. after performing peak calling with MACS, you want to know where the peaks hit).
  • Added BED Annotation output format. This is usefull to get all annotation intervals that intersect a set of variants (or genomic regions).
  • SnpSift filter:

    • Added generic index ('*') for variables, genotypes and effects. E.g.: ( 'GEN[*].GT = '1|1' )
    • Added support for 'EFF' and subfields (from SnpEff processed files). E.g.: ( EFF[*].EFFECT = 'NON_SYNONYMOUS_CODING' )
  • SnpSift intidx: Designed to extract a small number of intervals from huge VCF files. Added indexing using memory mapped I/O files for retrieving intervals from huge VCF files. Works really fast!
