Hi I want to bulk download all fastq files in a study from ENA http://www.ebi.ac.uk/ena/data/view/PRJEB3334
It is possible to click to the experiment and then download them but this would be very slow... any way to bulk download?
thanks - sorry what I actually mean to as was how to get all of those text files for all studies for this link: http://www.ebi.ac.uk/ena/data/view/PRJNA235852
I know how to go from there using wget with the text file.
Unless I am misinterpreting the statement above the second part of my answer has that info. 10th column in the file that gets downloaded using the TEXT link has the ftp links that you can use with
wget. You can get them with a simpleforbash loop or via multiple jobs, if you are using a cluster.It seems as though your project is actually a "Parent project" with many components. So, while you can get texts for them individually, but not all at once. I don't have an exact fix but in my experimenting with wget while trying to familiarize myself with FTP I have a makeshift answer that may work. But, honestly, it may be easier to just download each individually, as this will require some parsing on top of the download.
Concisely, I looked at 2 urls from different projects and found what they cease to have in common. Based on that you can get an FTP directory and get creative with wget. Based on that, this may work
wget -r -l2 -A.txt ftp://ftp.sra.ebi.ac.uk/vol1/fastq/SRR116/
(r is recursive, l3 tells it to go as far as 2 folders deep,and -A tells it what file type to look for) If you ultimately just want all the fastq.gz for this, I think you could also do this:
wget -r -l2 -A .gz ftp://ftp.sra.ebi.ac.uk/vol1/fastq/SRR116/
I'll repeat that I mostly found this while looking for solutions myself, and there is almost definitely a quicker way, but this seemed to work
