It looks like @CAsimonet has already gone through the instructions on the website and is have fine-tuned issues with getting a lot of specific files.

<p>I have asked this question in <a href="https://www.biostars.org/p/281809/" rel="nofollow noreferrer">biostars</a>, but I am trying here as well as people working with "omics" data might be able to help. I think my issue relates understanding how large data storage on online server works. I am trying to download large data from the Human Microbiome Project. These are available on online server and can be downloaded via aspera (ascp).</p>

<p>I can't figure out the right path to get the data. On <a href="https://www.hmpdacc.org/hmp/resources/download.php" rel="nofollow noreferrer">their website</a>, they give an example of command to retreive an example dataset:</p>

<pre><code> ascp -l 100M -QT user@aspera.hmpdacc.org:/ReferenceGenomes/test_genome.tar /path/to/local/directory
</code></pre>

<p>I executed this, using my own username, from this I am asked my password, and I can authenticate. But then I get the following error:</p>

<pre><code>(Error: Server aborted session: No such file or directory)
</code></pre>

<p>Then, I downloaded the manifest file via the HMP portal. In this manifest, they provide the path to which these files are supposed to be available. I tried to execute again the command with one of those path, provided by the manifest file:</p>

<pre><code>ascp -l 100M -QT user@aspera.hmpdacc.org:/files/5a950f27980b5d93e4c16da124000378  /path/to/local/directory
</code></pre>

<p>I again get the same error of "No such file or directory".</p>

<p>The <a href="http://downloads.hmpdacc.org/data2/hhs/genome/microbiome/wgs/analysis/hmwgsqc/v2/SRS013951.tar.bz2" rel="nofollow noreferrer">full url</a> provided by the manifest</p>

<p>I tried putting different chunks of this address into to ascp command but nothing works. I think there is something I don't understand about how to access the server via aspera and what is expected to go in this path. When I copy paste this url in google, this directly download the file I want. So I'm close, but I need to do it via command line as I need to download hundreds of these files and they are huge (6-10GB each).</p>

<p>How can I download the data of the human microbiome project using ascp?</p>

Is the manifest file a list of links like you provided? I mean to ask is the manifest file hundreds of lines with a URLs like `http://downloads.hmpdacc.org/data2/hhs/genome/microbiome/wgs/analysis/hmwgsqc/v2/SRS013951.tar.bz2`per line? It would helpful to see the format of the manifest file. The first 5 lines should suffice.

I can't test for ascp because they do not longer support my current setup but you can follow the [FTP instructions](https://www.hmpdacc.org/hmp/resources/ftp_public.php). With FileZilla:

url: public-ftp.ihmpdcc.org
