 The perl script INSTALL.pl may return errors as missing dependencies or other. For instance,the error `Bio::Root::Version is not installed` may be solved by running `sudo cpanm Bio::Root::Version`. You may have more than one such library to install. Refer to the github for the details.
 
-The installation from the perl script offers the choice to install cache files (most efficient use of vep) and FASTA files (to retrieve sequence data for HGVS notations) into `$HOME/.vep`. You may also install plugins for additional analyses. Download cache files for Homo Sapiens genome 99_GRCh37 (or newer). The total download size is about 12 GB of data so a stable and fast connection is required here. The FASTA file Homo_sapiens.GRCh37.75.dna.primary_assembly.fa.gz requires 882 MB of storage. *DO NOT FORGET* to unzip this file (or VEP will fail).
