text: user5190: I am trying to extract data from this:
  https://trace.ncbi.nlm.nih.gov/Traces/sra/?run=SRR6245218
  I installed SRA Toolkit, downloaded the SRR6245218 file and executed this:
  fastq-dump -X 5 SRR6245218 --fasta -O ./
  
  The result is a fasta file 900 bytes long, which does not contain the mitochondrial data that I need.
  What am I doing wrong?
  
  user3577: 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.
