This repository is archived and its functionality has been replaced by the new blat-based genome mapping pipeline.

This repository contains the code that is used internally for mapping RNAcentral sequences to their genomic locations based on the underlying INSDC accessions.

Example:

AL133244.1 (15569:15681) corresponds to human chromosome 2 (32945339:32945451).

Uses Ensembl Perl API and Bioperl.

• DBD::mysql for connecting to Ensembl
• DBD::Oracle for connecting to RNAcentral

# clone this repo
git clone https://github.com/RNAcentral/genome-mapper.git

# initialise submodules
cd genome-mapper
git submodule init
git submodule update

# optional: checkout the desired Ensembl branch

# optional: check that Ensembl connection is working
source setup.sh
perl ensembl/misc-scripts/ping_ensembl.pl

# make a copy of the params script and add the connection details
cp scripts/params_template.sh scripts/params.sh

The connection parameters for the RNAcentral database are stored in scripts/params.sh (excluded from version control).
