To upload new genome references (or new versions), please follow these instructions:
1 - Download the genome and annotation references from your species of interest from Ensembl (https://ftp.ensembl.org/). To achieve this you should:
Select the directory ´´pub/´´
Select the release folder of your choice (e.g., release-110)
Select ´´gtf/´´ folder or ´´dna/´´ folder to download annotation or genome files, respectively.
Select your organism of interest
Download the gtf.gz file for the annotation reference
Download the toplevel.fa.gz file for the genome reference
2 - Rename gtf and fasta files as follow:
gtf file - annotation_organism_ercc_sirv_biotyped.gtf
Example: Mus_musculus.GRCm39.110.gtf.gz renamed to annotation_organism_ercc_sirv_biotyped.gtf
fasta file - annotation_organism_ercc_sirv.fa
Example: Mus_musculus.GRCm39.dna.toplevel.fa.gz renamed to annotation_organism_ercc_sirv.fa
3 - Create a gene_description.txt file.
The gene_description.txt file is a tab separated file that contains two columns: Gene ID and Gene name.
To generate the gene_description.txt file, please use the command line presented below. This command line uses the annotation file to extract the Gene ID and Gene name information.
...
5 - Generate a final directory containing both genome and annotation files. To do this you need to:
Copy the files:
Code Block cp gene_description.txt annotation_organism_ercc_sirv.fa annotation_organism_ercc_sirv_biotyped.gtf annotation_organism_ercc_sirv.bed ./Directory_folder/
Compress the resulting folder (tar.gz):
| Code Block |
|---|
tar czfv Directory_folder.tar.gz Directory_folder |
...
By default, all uploaded files appear as have a designated type marked as “File”. To be used as a reference by the pipeline, the type of the uploaded file must be changed to ´´Genome´´ genome files must be marked as “Genome”. Please watch here our tutorial video on how to tag your file as a ´´Genome´´ type file here.
To change the file type, click on the file type icon (Can we insert the icon here?) in the type column to switch between ´´Ffile´´ and ´´Ggenome´´. Once marked as “Ggenome”, the file can be used as a reference in all your projects.
