A collaborator recently asked if I could help pull down a few thousand sequence files from the NCBI Sequence Read Archive (SRA) for a secondary analysis. This is a short post primarily to help me (and hopefully others) remember how to do this once you have a set of SRR IDs of interest. While I came across several great resources providing information on how to download SRA files using the SRA
29 Sep 2018 Downloading multiple samples from a entry at GEO Dataset you should be able to download raw data as .fastq (or other file format SRA-tools 30 Dec 2014 We have identified the NGS data in the NCBI SRA, and now it's time to download the file using the command line application SRA toolkit. fastq-dump can be used for local .sra files or for direct download from NCBI Multiple File Options Setting these options will produce more than 1 file, each of Python package for interacting with SRAdb and downloading datasets from SRA. pysradb can utilize a SQLite database file that has preprocessed metadata API changes where multiple redundant columns were output in sra-metadata Why is reads number of fastq less than that of SRA file? Metadata Download files from DDBJ ftp server at wget is a convenient way to download files over FTP. Metagenomic assemblies, where multiple genomes are assembled with high

Downloading read and analysis data. Sequencing read and analysis data are available for download through FTP and Aspara protocols in their original format and for read data also in an archive generated fastq formats described here. Submitted data files Cart and File Download. While browsing the GDC Data Portal, files can either be downloaded individually from File Summary Pages or collected in the file cart to be downloaded as a bundle. Clicking on the shopping cart icon that is next to any item in the GDC will add the item to your cart. Convert SRA to FASTQ format. To convert the example data to FASTQ, use the fastq-dump command from the SRA Toolkit on each SRA file. To install SRA Toolkit click here.. R can be used to construct the required shell commands and to automate the process, starting from the SraRunInfo.csv" metadata table, as follows: What is fastest way to download read data from NCBI SRA ? I would recommend downloading .sra file using aspera (it is the fastest i know as of now) and converting .sra to fastq using fastq fastq-dump.2.x err: name not found while resolving tree within virtual file system module - failed SRR*.sra The data are likely reference compressed and the toolkit is unable to acquire the reference sequence(s) needed to extract the .sra file.
