Psst! I've posted some details about my notebook setup here.
BAM files with sequence alignments sorted by genomic position seem to be the new currency of exchange for large-scale human genome sequencing projects. This is convenient and practical in many ways for many people. But in my current research I work a lot with tools that only want/need the sequence information and, for whatever reasons, support only FASTA or …more…
NCBI's Sequence Read Archive is the go-to repository for published genome-scale sequence data sets.
Although there are a variety of ways to download sequence data from SRA, the
fastq-dump command from the SRA Toolkit is the most convenient in my opinion.
In fact, with a few settings tweaks
fastq-dump can stream data directly from the SRA into an analysis pipeline …
Last night I started a batch job on our group's cluster to download and process 9 Illumina libraries from the NCBI SRA.
In the past, I have almost always downloaded such data via direct links to
.sra files on the SRA FTP site, and then converted these files to Fastq format using the
fastq-dump command from the SRA Toolkit.
