    iGenome ftp site

    Hi,

    Sorry for this naive question. I would like to get the GTF files from Illumina's iGenome ftp site, but don't have access. I can download from http://cufflinks.cbcb.umd.edu/igenomes.html

    but how to access from a linux server? It prompted for user name and pwd which were denied.

    thanks!

    Worked for me:
    ftp ftp://igenome:[email protected]

    I did this ...

    ftp> open ussd-ftp.illumina.com
    Connected to ussd-ftp.illumina.com.

    ....

    Better yet just use "wget".

    Search for wget for more info.

      Thank you. I thought that was what I entered. I will try again tomorrow.

        Both wget and get worked.

        is wget generally preferred becaused it downloads faster?

          wget is very convenient for scripting.
          For instance you can scrape the page, filter out the URLs, pick the ones you want and slap a "wget " in front and pipe it to a shell. Tricky but easily do-able with with a little experience.

          ftp and (sftp with -b parameter) is scriptable, too.

          They are both the same speed as they're written in C and implement the same protocol (though wget does support other protocols, notably the http protocol). Any difference you see are probably network congestion or the result of I/O caching.

              Sorry for reviving this old topic, but I cannot connect to ussd-ftp.illumina.com. It says : connection reset by peer.

              How can I download the human genome hg19?

                Are you behind an institutional firewall that is preventing you from downloading?
                The iGenomes/Illumina server is up and available.

                If you only need the hg19 sequence then you can get it from other locations:

                UCSC: http://hgdownload.soe.ucsc.edu/goldenPath/hg19/bigZips/
                Ensembl: ftp://ftp.ensembl.org/pub/release-73...o_sapiens/dna/
                NCBI: ftp://ftp.ncbi.nlm.nih.gov/genomes/H_sapiens/

                    Dear all, I cannot access the iGenome ftp server too. Is there some problem?

                    Thanks

                      Server is up and available. Local firewall may be preventing you from reaching the site.

                        Dear GenoMax I tried from different computers in different institution, so I don't think is a problem of firewall... have you tried to download this? ftp://ussd-ftp.illumina.com/Mus_musc..._GRCm38.tar.gz

                        Best and thanks for your prompt reply

                          The link you posted is working for me (with right login/password, see below).

                          You are trying to download a genome that is not listed on the iGenomes site (http://cufflinks.cbcb.umd.edu/igenomes.html). If you look at one of the existing download links at the igenomes site you will see the account name/password (embedded in the link) that you need to use for the FTP site (which will work for the link above).

                          Post #2 in this thread has the login information you need.

                            Many thanks for your advice. We have some IP problem apparently. We managed accessing a computer in another city(!). Many thanks again!

                              Nine Things a Sample Prep Scientist Thinks About Before Sequencing
                              by SEQadmin2


                              I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.


                              Here are nine questions we think about, in roughly the order they matter, before...

                              From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
                              by SEQadmin2


                              Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


                              The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

                              Single-Cell Sequencing at an Inflection Point: Early Impacts of New Platforms and Emerging Trends
                              by SEQadmin2


                              With the launch of new single-cell sequencing platforms in 2026, the field stands at an exciting inflection point. This article surveys the most impactful advances in the field and discusses how they’re reshaping research in cancer, immunology, and beyond.


                              Introduction

                              Single-cell sequencing technologies have undergone remarkable advances over the past decade, transitioning from low-throughput experimental approaches to highly scalable platforms capable of...
