+# Submission
+
+Utility scripts for data upload to ENA.
+
+- [EMBL format conversion](convert_to_embl.sh) for an annotated genome (Fasta + GFF3) - inspired
+  from a [prokka issue](https://github.com/tseemann/prokka/issues/145), leading to
+  [GFF3toEMBL](https://github.com/sanger-pathogens/gff3toembl) and eventually to the real solution,
+  [EMBLmyGFF3](https://github.com/NBISweden/EMBLmyGFF3).
+- A [Python script](txome_manifest.py) to batch-create manifest files for de novo transcriptome
+  submissions to ENA.
