StORF-Reporter has now been published in NAR: https://doi.org/10.1093/nar/gkad814

StORF-Reporter, a toolkit that returns missed CDS genes from the Unannotated Regions (URs) of prokaryotic genomes.

Please use `pip3 install StORF-Reporter' to install StORF-Reporter.

This will also install the python-standard library numpy (>=1.22.0,<1.24.0), Pyrodigal - (https://github.com/althonos/pyrodigal) and ORForise (https://github.com/NickJD/ORForise).

Consider using '--no-cache-dir' with pip to ensure the download of the newest version of StORF-Reporter.

Please Note: To report Con-StORFs (Pseudogenes and genes that have alternative use of stop codons), use "-con_storfs True". To disable the reporting of StORFs use "-con_only".

The directory "Test_Datasets" is provided to confirm functionality of StORF-Reporter.

StORF-Reporter:

Most common use cases -

Supplement a current annotation from a tool such as Prokka or Bakta. A new GFF file will be created compatible with downstream pangenome analysis tools such as Roary and Panaroo.

For use on a single Prokka/Bakta output directory - Will also create a new fasta file with Prokka/Bakta genes and StORF sequences.

StORF-Reporter -anno Prokka Out_Dir -p .../Test_Datasets/Prokka_E-coli/

For use on multiple Prokka/Bakta output directies - Will also create a new fasta file with Prokka/Bakta genes and StORF sequences.

StORF-Reporter -anno Prokka Multiple_Out_Dirs -p ../Test_Datasets/Multi_Prokka_Outs

For use on a directory containing multiple Prokka/Bakta output gffs - Only produces new GFF files.

StORF-Reporter -anno Prokka Multiple_GFFs -p .../Test_Datasets/Prokka_Outputs/

For use on a GFF file from a CDS prediction tool such as Prodigal - Provide a GFF file and StORF-Reporter will find the matching .fa/.fasta/.fna (must have the same name).

StORF-Reporter -anno Feature_Types Single_Genome -p .../Test_Datasets/Matching_GFF_FASTA/Myco.gff

For use on a directory containing multiple GFF files from a CDS prediction tool such as Prodigal - StORF-Reporter will find the matching .fa/.fasta/.fna (must have the same name).

StORF-Reporter -anno Feature_Types Multiple_Genomes -p .../Test_Datasets/Matching_GFF_FASTA/

For use on a directory containing multiple GFF files with embedded FASTA.

StORF-Reporter -anno Feature_Types Multiple_Combined_GFFs -p .../Test_Datasets/Combined_GFFs/

To perform a fresh end-to-end annotation of a genome without an annotation, StORF-Reporter will use Pyrodigal to predict CDS genes and then supplement with StORFs.

                        Are StORFs to be extracted from Combined GFF/FASTA or Separate GFF/FASTA files?
  -p PATH               Provide input file or directory path

Output:
  -gff_out {True,False}
                        Default - False: Output StORFs in GFF format
  -oname O_NAME         Default - Appends '_Extracted_StORFs' to end of input GFF filename
  -odir O_DIR           Default - Same directory as input FASTA
  -gz {True,False}      Default - False: Output as .gz

Misc:
  -verbose {True,False}
                        Default - False: Print out runtime messages
