- 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 /my/home/kchennen/.vep
Do you want to install any cache files (y/n)? y
Cache directory /my/home/kchennen/.vep 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

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 /my/home/kchennen/.vep
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 /my/home/kchennen/.vep/homo_sapiens/73/Homo_sapiens.GRCh37.73.dna.primary_assembly.fa"
