Downloading sra files geoquery

This will download the SRA file (in sra format) and then convert them to fastq file for you. If your SRA file is paired, you will still end up with a single fastq file,

Convert SRA file into other biological file format (eg. FASTA, ABI, SAM, QSEQ, SFF) Retrieve small subset of large files (eg. sequences, alignment) Search within SRA files and fetch specific sequences; Allow to use Aspera client ascp for much faster download (Aspera client should have installed) Download and install NCBI SRA toolkit directory where the metadata files will be saved. geo_only: logical, whether to download GEO metadata only. Default is FALSE. If TRUE, then SRA metadata will not be downloaded. download_method: download method for GEOquery. See 'download.file' from R package utils for details. Default is 'libcurl'.

I often times have to do manual download by copying links of every SRA dataset by hand and use wget. I am wondering is there any simplest approach than manual copying of links ? Thanx in advance. For ex: How can I download all the data related to SRP026197 ? NCBI GEO allows supplemental files to be attached to GEO Series (GSE), GEO platforms (GPL), and GEO samples (GSM). This function "knows" how to get these files based on the GEO accession. No parsing of the downloaded files is attempted, since the file format is not generally knowable by the computer. Fulltext search in the package make querying metadata very flexible and powerful. fastq and sra files can be downloaded for doing alignment locally. Beside ftp protocol, the SRAdb has funcitons supporting fastp protocol (ascp from Aspera Connect) for faster downloading large data files over long distance. Where I need to download a separate file for each chromosome but the download is very fast (4 Gb in about 10 minutes) and the output file is a BAM file which means no other tool is needed. SRA toolkit, following their manual, I run this command: sam-dump SRR925780 | samtools view -bS - > SRR925780.bam. It takes about 3 hours to download and

In some cases, users may want to download SRA data and retain a copy. To download using NCBI's 'prefetch' tool, you would need to set up your own configuration file for the NCBI SRA toolkit. Use the command vdb-config to set up a directory for downloading. 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.

Given the rich and varied nature of this resource, it is only natural to want to apply BioConductor tools to these data. GEOquery is the bridge between GEO and BioConductor.

for high throughput file transfer with NCBI. There are now many cases where large file transfers, greater than 1 gigabyte (Gb), are commonplace and a single download session may involve hundreds of such files. As the sizes of the datasets have increased, we have found that the traditional methods of ftp or http do not have the performance

Detailed information regarding the usage of individual tools in the SRA Toolkit can be found on the tool-specific documentation pages. All available SRA files are identified by downloading the GEO series (GSE) and GEO samples (GSM and SRA information) using the GEOquery Bioconductor package 40.

I finally got the data by downloading the big data file myself and 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. The computer does not have enough hardware resources to cope with the opening of the SRA file. Drivers of equipment used by the computer to open a SRA file are out of date. If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the SRA file should operate with your programs without any problem.
