SYNOPSIS

       snpEff [command] [options] [files]

AVAILABLE COMMANDS

       [err|ann]
              Annotate  variants  /  calculate  effects (you can use either 'ann' or 'eff', they mean the same).
              Default: ann (no command or 'ann').

       build  Build a SnpEff database.

       buildNextProt
              Build a SnpEff for NextProt (using NextProt's XML files).

       cds    Compare CDS sequences calculated from a SnpEff database to the one  in  a  FASTA  file.  Used  for
              checking databases correctness.

       closest
              Annotate the closest genomic region.

       count  Count how many intervals (from a BAM, BED or VCF file) overlap with each genomic interval.

       databases
              Show currently available databases (from local config file).

       download
              Download a SnpEff database.

       dump   Dump to STDOUT a SnpEff database (mostly used for debugging).

       genes2bed
              Create a bed file from a genes list.

       len    Calculate total genomic length for each marker type.

       pdb    Build interaction database (based on PDB data).

       protein
              Compare  protein  sequences calculated from a SnpEff database to the one in a FASTA file. Used for
              checking databases correctness.

       seq    Show sequence (from command line) translation.

       show   Show a text representation of genes or transcripts coordinates, DNA sequence and protein sequence.

       translocReport
              Create a translocations report (from VCF file).
