RNA-seq reads were aligned to the reference genome and transcriptome by hisat2, filtering contiguous and canonical splice reads.

Next-generation sequencing technologies can produce tens of millions of reads, often paired-end, from transcripts or genomes. But few programs can align RNA on the genome and accurately discover introns, especially with long reads.

The installation is finished now, then I will introduce how to download data in SRA and ENA with ascp. ascp one-liner: ascp [options] target-file storage-directory，online documentation. Some need-to-know options-v verbose mode, let you know what the program is doing in time, better add it for debugging.-T Disable encryption, otherwise downloading will be interrupted sometimes. Remote files or folders, specified as a character vector or string scalar. To match multiple files or folders on the FTP server, you can include a wildcard character (*) in contents.For example, if you specify contents as *.docx, then mget downloads all files whose names end with .docx. Chipster will try to assign the files to directions based on file names. This assumes the files are named so that the beginning of the name is identical and the directions are specified with _1 and _2, e.g. Abc123_1, Abc123_2. If your files are named differently, you need to provide list files to make sure the files are assigned correctly Download multiple SRA files. Ask Question Asked 2 years, 1 month ago.

Step 2: Download the FASTQ files and align with hisat2. First, we will ~/sratoolkit.2.9.4-centos_linux64/bin/fastq-dump -A SRR3621123 >& SRR3621123.err
If you go to the SRA run selector at the bottom of the GEO page, it lists the SRA accessions for each of the samples. Looking at the first sample, it says that the file is 1.46 GB in size. But when I use the fastq-dump tool, it gave me a file that was 2.8 GB, and it might've been more if I hadn't stopped the download. Tophat2 : Download, build reference genome and align the reads to the reference genome Getting started with HISAT, StringTie, and Ballgown bioinformatics Davo October 25, 2017 13 A popular toolset used for analysing RNA-seq data is the tuxedo suite, which consists of TopHat and Cufflinks . Beside the index files under /fdb/hisat, HISAT on Biowulf has been built with sra support. A local copy of the SRA Refseq reference data is maintained in /fdb/sra/refseq, and the NCBI SRA toolkit has been configured on Biowulf to : first check if the required reference data is available in the local copy The following are the steps I have taken in order to obtain the poor alignment from hisat2: NCBI GEO provides the sample in sra format and so I had to use the SRA Toolkit to convert from sra to fastq. On my local server I would complete this action by using the command ./fastq-dump SRR1103937. HISAT2 2.04 Windows binaries (Old Version - provided for reference) NEW! HISAT2 2.1 Windows binaries - (Windows Binaries Release Note) - Note: apparently the PERL script in this package may in some situations fail to work with the new windows binary. Using the previous version of the PERL script (form HISAT 2.04) solves the problems RNASeq for Model Plant (Arabidopsis thaliana) This tutorial will serve as a guideline for how to go about analyzing RNA sequencing data when a reference genome is available. We will go through alignment of the reads to the reference genome with HISAT2, conversion of the files to raw counts with stringtie and analysis of the counts with ballgown.
In this sense, KnowSeq allows aligning raw data from the original fastq or sra files, by using the most renowned aligners such as tophat2, hisat2, salmon and kallisto. HISAT2 outputs alignments in SAM format, enabling interoperation with a large number of other tools (e.g. SAMtools, GATK) that use SAM. HISAT2 is distributed under the GPLv3 license, and it runs on the command line under Linux, Mac OS X and Windows. Obtaining HISAT2. Download HISAT2 sources and binaries from the Releases sections on the right side. Index files are moved to a different location. 8/30/2019 Due to a high volume of index downloads, we have moved HISAT2 index files to a different location in order to provide faster download speed. If you use wget or curl to download index files, then you may need to use the following commands to get the correct file name. Downloading SRA data using the SRA Toolkit. The SRA Toolkit has the capacity to download data files directly (when properly configured) simply by calling a Toolkit command and specifying the accession of interest.For example: $ fastq-dump -X 5 -Z SRR390728
