Script to thousands of exons

[Sofia Silva]

Hi!

I'm not an expert on informatics so i thought some of you may be able to help me...
I have a list of about 5000 genes and i want to download only the exons of each of them (maybe through ensembl site). It's too much to do it "by hand" and i really don't have that time.
Do you have any idea of how could i do it? Any script that could help me with this?

Thank you in advance for all the attention
Best regards,
Sofia

No script should be needed. Use BioMart to do this yourself.

Go to Ensembl. Click on BioMart link at the top. A new page should open. Going to show an example for human genome. Hopefully genome of your interest is in BioMart.

1. Choose DB --> Ensembl Genes
2. Choose Dataset --> Human (as example)
3. Click on Filters in left column. Many choices open up on right. Choose what you need
4. Checking Source --> Ensembl for this example
5. Click on the Attributes in left pane
6. Select Sequence button in right pane
7. Expand "Sequences" options by clicking on + sign
8. Select "Exon sequences" radio button
9. Expand "Header Information" by clicking on + sign. Select options as needed
10. Click on the "Count" button at top left corner (e.g. 6460 / 63967 Genes)
11. Hit "Results" button next to count.
12. Use "Export results to file" --> "Fasta"
13. Click on "Go" to download the file (choose unique only if you want that).
14. You are done!
