How to validate fastq.gz file from sra download

Mar 3, 2016 In some cases we have found that errors in the validation of the data can mean that data is corrupted when it is downloaded from these repositories. The SRA file is a composite file, much like a zip or tar file, which can contain I can pull down the sra file from NCBI, and run fastq-dump successfully on it, 

Dec 24, 2017 What's more, you could download directly fastq.gz files from it. database first with the SRR (SRA Run) accession number to check if it is there.

You will need to get the ascp program as described in how to download files using aspera. Then you will e.g ftp://ftp.sra.ebi.ac.uk/vol1/fastq/ERR008/ERR008901/ERR008901_1.fastq.gz You can check the version of ascp you have using:

The preferred format in QIIME for Illumina data is fastq. split_libraries_fastq.py can work with either gzip-compressed (e.g., .fastq.gz) or uncompressed (e.g. .fastq) fastq files. The resulting fastq files can then be processed with split_libraries_fastq.py. If not, check a qseq file corresponding to another read number (e.g.,  Aug 1, 2018 Downloading SRA files; Downloading FASTQ files; Saving downloads links Query SRA data and metadata; Check for availability and size of .net/connect/bin/ibm-aspera-connect-3.8.1.161274-linux-g2.12-64.tar.gz tar  Command "getwd()" in R, copy your fastq or fastq.gz files to a directory R") biocLite("SRAdb") } ##Download fastq files (in SRA project SRP003951 for output_file=output.file, nthreads=3) } }else{ cat("Check that all fastq files are paired\n") }. Jun 3, 2017 In my test just now, using fastq-dump , I get a throughput of ~11.5 MiB/s, In my case, I've just started downloading some files from a MinION sequencing run. vol1/ERA932/ERA932268/oxfordnanopore_native/20160804_Mock.tar.gz .

A typical procedure is having to convert .sra files into fastq. The command is as follows: fastq-dump --gzip --split-3 SRR493366.sra.
