<p>Your command is fine. It is working as expected. Did you intend to include <code>-X 5</code> in your command? That restricts the number of spots to 5. If you drop it, you will download the entire set of 2563898 spots. </p>

I see. I expected to get mitochondrion DNA. Not sure what I am getting here. But I already found it in fasta format somewhere else.

<p>I am trying to extract data from this:
<a href="https://trace.ncbi.nlm.nih.gov/Traces/sra/?run=SRR6245218" rel="nofollow noreferrer">https://trace.ncbi.nlm.nih.gov/Traces/sra/?run=SRR6245218</a></p>

<p>I installed SRA Toolkit, downloaded the SRR6245218 file and executed this:</p>

<pre><code>fastq-dump -X 5 SRR6245218 --fasta -O ./
</code></pre>

<p>The result is a fasta file 900 bytes long, which does not contain the mitochondrial data that I need.
What am I doing wrong?</p>

Your command is fine. It is working as expected. Did you intend to include `-X 5` in your command? That restricts the number of spots to 5. If you drop it, you will download the entire set of 2563898 spots.
