Body: <p>I have a genome-wide list of germline SNPs and short indels for Arabidopsis thaliana, which I generated with Varscan. Regardless of the tool used to generate them, I would like to annotate them, i.e. knowing which ones can cause an aminoacid change or an early stop, using the default Arabidopsis thaliana Columbia 0 cultivar, for which I have both the sequence (FASTA from TAIR10) and the updated annotation (GFF from Araport).</p>

  I recently used [SIFT4G](http://sift.bii.a-star.edu.sg/sift4g/AnnotateVariants.html) to predict the deleteriousness for a SNP dataset in Arabidopsis.
  
  I noticed that besides this, the tool also provides annotation for the SNPs (like gene region, amino acid substitution, start/stop etc.)
  
  They have an Arabidopsis database readily available so you don't have to generate your own. Your input should be enough to run the tool, although you might have to do some reformatting (the tool requires VCF format files).
  
  One thing though, not all SNPs are considered by the tool. Intronic SNPs and SNPs outside gene regions are ignored afaik.
