Load IPD-IMGT/HLA database

Use the Python py-ard package developed by the NMDP to initialize the IPD-IMGT/HLA database.

Usage

db_initialize(data_dir, imgt_version = "Latest", strict_mode = TRUE)

Arguments

data_dir

Path to the folder where the SQLite database (~600MB) is or should be stored. If no database exists on disk, it will be downloaded.

imgt_version

Four-digit version number of the database release that should be used. Defaults to the most recent release ("Latest").

strict_mode

Defaults to TRUE; if FALSE, functions like is_in_ipd_db() will perform a less strict validation of alleles in the database (e.g. some alleles that were deleted or renamed in a newer version of the database will still pass).

Value

A Python database connection object, which should be passed to other functions that make use of the database.

Examples

if (FALSE) { # \dontrun{
ard <- db_initialize(path.expand("~/ipd_db"), imgt_version = "3510")
} # }
