News:Tell us what you think of the ENA browser? 1 Entering edit mode 7.8 years ago Laura ★ 1.8k We would like to improve the browsing services that the ENA provides. Your feedback on how you use the service would be greatly appreciated. There are two surveys (neither should take you more than 5 minutes) Please let us know how you use the service and what we could do to make your tasks easier. thanks Laura ena • 3.6k views ADD COMMENT • link updated 16 months ago by Ram 44k • written 7.8 years ago by Laura ★ 1.8k 5 Entering edit mode 7.8 years ago Istvan Albert 101k I think you should provide a tool to search ENA the same way like Entrez Direct does. The simplicity of being able to do simply do a: or creates a massive advantage for NCBI when it comes my choice of downloading data or creating reusable piplines. In my opinion scientists that write new software that interacts with existing data are the ones driving innovation. ADD COMMENT • link 7.8 years ago by Istvan Albert 101k Entering edit mode In context of automating pipelines it would be an essential/useful addition, no argument there. Having an additional option is always great but what information can one get from ENA that can't be found using Entrez direct (that is a real question :) )? Sometimes having multiple options (that do more or less the same thing) confuses (new) users and becomes a matter of personal preference for educators. ADD REPLY • link 7.8 years ago by GenoMax 144k 2 Entering edit mode I believe that ENA has richer set of annotations than NCBI - or at least better organized and more in tune with what biologists want. It is just not easy to get to it if you don't want to use a web browser. There is a web API but even I found that to be too complicated and too low level - though I am not shy about using command line. ADD REPLY • link 7.8 years ago by Istvan Albert 101k Entering edit mode The ENA has programmatic query services http://www.ebi.ac.uk/ena/browse/programmatic-access For searching the catalogue there are a number of rest end points http://www.ebi.ac.uk/ena/browse/search-rest thanks ADD REPLY • link 7.8 years ago by Laura ★ 1.8k Entering edit mode neither of which is similar to what I have described - FWIW I don't consider the link below a useful programmatic access (taken from one of the resources that you mention). As a matter of that that is really what would make the ENA more useful. Instead of obscure lengthy links having a tool that builds us these links. That is what Entrez Direct does. ADD REPLY • link 7.8 years ago by Istvan Albert 101k Entering edit mode As mentioned in the post below, yes we have much simpler queries for programmatically fetching data and performing text searches, but yes the advanced search is complicated. Unfortunately there is no easy way to get around this when wanting to target search terms to specific fields within a record. We are however wanting to start offering downloadable scripts for performing common actions within ENA next year, therefore this feedback is valuable. If you have key things that you feel these scripts should do, please feel free to start posting them here and we'll see what we can do. ADD REPLY • link 7.8 years ago by Nicole ▴ 10 Entering edit mode This is something that got clarified in my own mind while writing the Biostar Handbook, teaching courses and observing how people interact with and work with bioinformatics data. The graphical interfaces such as ENA interfaces are good to explore data but completely inappropriate to reproduce results or to communicate with another fellow scientist of what has actually been done. https://read.biostarhandbook.com/ In the whole book, which is now clocking in at more than 500 pages there is not a single instance where we would access data via GUI via a GUI interface - and it works like a charm. And I think that is a the right way to go about it! The main point I am trying to make is we should use the browser to figure out what is there but then there absolutely needs to be a way to get the same information in simple and unambiguous way that allows the users to go on their own explorations. A lot is made about reproducible research (or lack thereof) and one key component to that is well defined data access. Lengthy URLs that wrap around many rows and are full of weird characters in them are not a good solution - that is impossible to parse visually or to explain to others. My opinion is that, having a well documented and simple programmatic interface will be the deciding factor in choosing one resource over the other. ADD REPLY • link 7.8 years ago by Istvan Albert 101k Entering edit mode We have now announced some new tools for retrieving data from ENA. This includes one that allows you to download sequences more easily as requested here. Please see our news item more more info: http://www.ebi.ac.uk/about/news/service-news/new-tools-download-data-ena ADD REPLY • link 7.2 years ago by Nicole ▴ 10 1 Entering edit mode 7.8 years ago cochrane ▴ 10 Yes - lots of services available from EMBL-EBI. For retrieval:curl "http://www.ebi.ac.uk/ena/data/view/<accession>&display=text" will retrieve any record given the accession.e.g. curl "http://www.ebi.ac.uk/ena/data/view/AF086833&display=text"This accepts ranges and lists and gives a number of format options for different data types. See http://www.ebi.ac.uk/ena/browse/data-retrieval-rest#retrieval_single_identifier for more details. For search:There is an interactive interface that can be used to build up queries at http://www.ebi.ac.uk/ena/data/warehouse/search. The 'Search query' box shows a search being built up as you fill in fields and you can edit directly. Based on this, you can pull the whole thing out into a standard REST call...

As someone who is part of the Ensembl project I'm not aware of an active project to develop such a tool. However it sounds like an interesting idea for sure.

It always comes down to limited resources and how to distribute them We promise to be patient while you consider this request. ADD REPLY • link 7.7 years ago by GenoMax 144k Entering edit mode Hi I think you are confusing the ENA with Ensembl. The ENA is the nucleotide archive hosted at EMBL-EBI and is a different service to Ensembl. Ensembl, the genome browser does source data from the ENA but isn't the same entity. Nicole works for the ENA not Ensembl ADD REPLY • link 7.7 years ago by Laura ★ 1.8k Entering edit mode You are correct. My apologies. Got carried away there for a time. ADD REPLY • link 7.7 years ago by GenoMax 144k Entering edit mode I would suggest to look into how Entrez Direct works and how one can chain its actions together to full appreciate the level innovation there. While the Entrez Direct implementation is a bit choppy (mainly the error reporting is lacking) it has functionalities that make it uniquely powerful. It is just that many people don't know about it yet. ADD REPLY • link 7.8 years ago by Istvan Albert 101k 1 Entering edit mode Thanks for the feedback Istvan and genomax2. I have had a look at Entrez Direct and will use it and your comments here when building a specification for our planned scripts. And yes, error reporting is an important requirement. You will be happy to know that this work is considered to be high-priority for 2017. I'll make a note to make any announcements regarding release of new programmatic tools here, but if you would like to make sure you are kept abreast of any and all announcements regarding new ENA functionality (or service interruptions), please consider signing up to our ena-announce mailing list: http://listserver.ebi.ac.uk/mailman/listinfo/ena-announce ADD REPLY • link 7.7 years ago by Nicole ▴ 10 Entering edit mode Hi Nicole - I was wondering if there's been any progress on this? Just got curious if there's a tool similar to Entrez-direct for ENA.

Entrez eutils I should have referred to such a solution, Ensembl ENA eutils.
