|PRJNA36679||SRP000694||Genome sequencing of 192 inbred strains of Drosophila melanogaster to serve as a reference panel for the study of complex traits|
A resource of 192 inbred D. melanogaster lines created from a single natural population that have been both extensively sequenced and extensively phenotyped for quantitative traits. This resource will be a valuable tool for associating genotype to phenotype for quantitative traits.
You need SRA Toolkit to operate on SRA runs.
Default toolkit configuration enables it to find and retrieve SRA runs by accession. It also downloads (and cache) only the part of data you really need. For example quality scores represent a majority of data volume and you may not need them if you dump fasta only (versus fastq). Or if you are looking at particular gene you may not need reads aligned to other regions or not aligned at all. Same way if you use GATK with enabled SRA support you need only SRA run accessions to fire your process.
fastq-dump will dump reads in a number of "standard" fastq and fasta formats.
vdb-dump is also capable of producing fasta and fastq (beside other formats). It dumps data much faster then fastq-dump but ordering of reads may be different and it does not produce split-read multi-file output.
Prefetch tool will help you cache all data in advance if you plan to run data analysis in environment where getting data from NCBI at run time is unfeasible.
