Download sequencing data

Sequence Read Archive (SRA) / Gene Expression Omnibus (GEO)

# Download SRA file directly with ascp:
~/.aspera/connect/bin/ascp \
    -i ~/.aspera/connect/etc/asperaweb_id_dsa.openssh \
    -pQTk1 \
    -l 1000m \
    dbtest@sra-download.ncbi.nlm.nih.gov:data/sracloud/traces/sra46/SRR/005227/SRR5353377 \
    SRR5353377.sra

# Convert SRA file to gzipped FASTQ files with fastq-dump (SRA toolkit).
fastq-dump --gzip --split-files SRR5353377.sra

# Convert SRA file to FASTQ with fasterq-dump (SRA toolkit) and compress FASTQ files with gzip.
fasterq-dump --split-files SRR5353377.sra
gzip SRR5353377_1.fastq
gzip SRR5353377_2.fastq

Downloading data from the SRA website

Download SRA file with prefetch (of SRA toolkit which uses ascp (-t fasp)

# Use prefetch (SRA toolkit) to download SRA file:
#   - SRA files will be written to: $HOME/ncbi/public/sra/
#   - If your HOME dir is constrained in space, make a symlink:
#       ln -s /dir_with_lots_of_free_space/ncbi ${HOME}/ncbi
prefetch -v -t fasp SRR5353377

# Convert SRA file to gzipped FASTQ files with fastq-dump (SRA toolkit).
fastq-dump --gzip --split-files SRR5353377

# Convert SRA file to FASTQ with fasterq-dump (SRA toolkit) and compress FASTQ files with gzip.
fasterq-dump --split-files SRR5353377
gzip SRR5353377_1.fastq
gzip SRR5353377_2.fastq
