Long Reads Annotation pipeline
Full Description

LoReAn (Long Read Annotation) for automated eukaryotic genome annotation incorporating long-reads

The LoReAn software is an automated annotation pipeline designed for eukaryotic genome annotation. It is built using previously
defined annotation rationale and programs, but the key improvement is the incorporation of single-molecule cDNA sequencing data,
such as that produced from Oxford Nanopore and from PacBio.
We find this significantly improves automated annotations and reduces the requirments for time-consuming manual annotation.

We are working to improve LoReAn documentation. Meanwhile, some more LoReAn information can be found at
bioRxiv. For those familar with the annotation process and
with docker, there should be enough infomation to run the program. If you have problems, please open an issue.

This is how LoReAn works: LoReAn schematic view


LoReAn requires three mandatory files:

  • Protein Sequences
  • Reference genome sequence
  • Genome name

To install the software:

Please see the installation instructions for details.

The software can be run after installing by: -pr protein.fasta -sp spacies genome.fasta 

The full list of options can be found at option instructions or by: --help

LoReAn can run BRAKER to improve Augustus gene prediction;

To do so, short reads from RNA-seq or long reads RNA-seq need to be provided


We made available two datasets that can be used to test LoReAn. The 1st dataset is from Nanopore data of Verticillium dahliae
strain JR2 while the second is from PacBio data of Plicaturopsis crispa. Both datasets can be dowloaded from
