Variant Effect Predictor

  • Installation on studio with Raymond

 > cd variant_effect_predictor
  • Install the API with a local cache in /biolo/vep/cache
 > perl INSTALL.pl -c /biolo/vep/cache
   Hello! This installer is configured to install v73 of the Ensembl API for use by the VEP.
   It will not affect any existing installations of the Ensembl API that you may have.
   
   It will also download and install cache files from Ensembl's FTP server.
   Checking for installed versions of the Ensembl API...done
   It looks like you already have v73 of the API installed.
   You shouldn't need to install the API
   
   Skip to the next step (n) to install cache files
   
   Do you want to continue installing the API (y/n)?y

  • Install local cache for database connections for homo sapiens
       The VEP can either connect to remote or local databases, or use local cache files. Using local cache files is the fastest and most efficient way to run the VEP
       Cache files will be stored in /biolo/vep/cache
       Do you want to install any cache files (y/n)? y
       Cache directory /biolo/vep/cache does not exists - do you want to create it (y/n)? y
       
       Downloading list of available cache files
       The following species/files are available; which do you want (can specify multiple separated by spaces): 
       1 : ailuropoda_melanoleuca_vep_73.tar.gz
       2 : anas_platyrhynchos_vep_73.tar.gz
       3 : anolis_carolinensis_vep_73.tar.gz
       ...
       25 : homo_sapiens_refseq_vep_73.tar.gz
       26 : homo_sapiens_vep_73.tar.gz
       ...

        - downloading ftp://ftp.ensembl.org/pub/release-73/variation/VEP/homo_sapiens_vep_73.tar.gz
       ** GET ftp://ftp.ensembl.org:21/pub/release-73/variation/VEP/homo_sapiens_vep_73.tar.gz ==> 200 OK (305s)
        - unpacking homo_sapiens_vep_73.tar.gz
       
      Download FASTA files for homo sapiens
      
       The VEP can use FASTA files to retrieve sequence data for HGVS notations and reference sequence checks.
       FASTA files will be stored in /biolo/vep/cache
       Do you want to install any FASTA files (y/n)? y
       FASTA files for the following species are available; which do you want (can specify multiple separated by spaces, "0" to install for species specified for cache download): 
       1 : ailuropoda_melanoleuca
       2 : anas_platyrhynchos
       3 : ancestral_alleles
       ...

       Extracting data
       The FASTA file should be automatically detected by the VEP when using --cache or --offline. If it is not, use "--fasta /biolo/vep/cache/homo_sapiens/73/Homo_sapiens.GRCh37.73.dna.primary_assembly.fa"        
       Success
  • Configure
    • Add plugins
    • Create the configuration file vep.ini in /biolo/vep/cache
