The development of GDV led to a few different types of genome browsers along the way, each one originally delivering visual displays for particular datasets. Moreover, unlike GDV, these older browsers are no longer under active development and the data has not been updated to meet changing needs of the communities they were developed to serve.
For these reasons we will retire these browsers in April Please see details below for more information on the data displayed in these browsers and how to access and display these data now through GDV and other means. Are you a researcher who works on gene biology and are interested in alternative splice patterns in your gene or genes of interest?
If so, be sure to explore the intron feature evidence available in graphics views of genome assemblies annotated by NCBI. You can view the NCBI evidence used for calling splice variant for genes, add other intron feature evidence tracks, and use new display and filter options that make it easier to interpret the data.
Figure 1. Mousing-over an intron feature activates a tooltip that shows details such as the number of reads with the splice site, the location on the chromosome, the length of the intron and the donor and acceptor bases at the splice site.
The Intropolis track was added through the search feature of the Configure Tracks menu and configured bottom menu so that the features were sorted by strand and filtered so that only features with greater than reads appear. Some examples are listed below:. You can use any of these queries or the ones described below for assembly aliases either on the GDV landing page or in the GDV search box Figure 1.

For UCSC we can also select the annotation type. Since we did not specify the provider here, genomepy will use the first provider it can find with xenTro9. Next, the genome is downloaded to the directory specified in the config file.
You can use a regular expression to filter for matching sequences or non-matching sequences by using the --no-match option. For instance, the following command downloads hg38 and saves only the major chromosomes:.
By default, sequences are soft-masked. Use -m hard for hard masking, or -m none for no masking. You can choose to download gene annotation files with the --annotation option.
This installs the genome under the filename of the link, but can be changed with the --localname option. If you add the --annotation flag, genomepy will search the remote directory for an annotation file as well. Should this fail, you can also add a url to the annotation with --URL-to-annotation. This includes the original name, download location and other genomepy operations such as regex filtering and time.
Note that searching doesn't work flawlessly, so try a few variations if you don't get any results. You can constrain the genome list by using the -p option to search only a specific provider. Note that the first time you run genomepy search or list the command will take a while as the genome lists have to be downloaded. The lists are cached locally, which will save time later.
You can also delete this directory to clean the cache using genomepy clean. Check out our Python API documentation here. The genomepy. Genome method returns a Genome object. This has all the functionality of a pyfaidx. Fasta object, see the documentation for more examples on how to use this.
Genomepy utilizes external databases to obtain your files. Unfortunately this sometimes causes issues. Here are some of the more common issues, with solutions. Let us know if you encounter issues you cannot solve by creating a new issue.
Occasionally one of the providers experience connection issues, which can last anywhere between minutes to hours. When this happens genomepy will warn that the provider appears offline, or that the URL seems broken. If the issue does not pass, you can try to reset genomepy. Simply run genomepy clean on the command line, or run genomepy. Genomepy stores provider data on your computer to rerun it faster later. If a provider was offline during this time, it may miss parts of the data. To re-download the data, remove the local data with genomepy clean , then search for your genome again.
Sadly, not everything naming, structure, filenames is always consistent on the provider end. See the section on converting coordinates for information on assembly migration tools. The initial release of a new genome assembly typically contains a small subset of core annotation tracks.
New tracks are added as they are generated. In many cases, our annotation tracks are contributed by scientists not affiliated with UCSC who must first obtain the sequence, repeatmasked data, etc.
If you have need of an annotation that has not appeared on an assembly within a month or so of its release, feel free to send an inquiry to genome soe. Rest assured that work will continue. There will be updates to the assembly over the next several years. This has been the case for all other finished i. For example, the C.

WS Available ce4 Jan. WS Available ce2 Mar. WS Archived C. Non-perfect matches can be due to a number of factors: different or not included chrMT genome sequences in an assembly identical duplicated sequences present or absent from an assembly some smaller contigs not included in an assembly slight differences in versions of assemblies where some contain sequences not in the other assembly Comparison of UCSC and NCBI human assemblies How do the human assemblies displayed in the UCSC Genome Browser differ from the NCBI human assemblies?
If you want to filter for the "relation to type material" column of the assembly summary file, you can use the --type-materials option. Multiple values can be given, separated by comma:. By default, ncbi-genome-download caches the assembly summary files for the respective taxonomic groups for one day. You can skip using the cache file by using the --no-cache option. The output of --help also shows the cache directory, should you want to remove any of the cached files.
You can also use it as a method call. Note : To specify a taxonomic group, like bacteria , use the group keyword. This script lets you find out what TaxIDs to pass to ngd , and will write a simple one-item-per-line file to pass in to it. It utilises the ete3 toolkit, so refer to their site to install the dependency if it's not already satisfied. You can query the database using a particular TaxID, or a scientific name.
The primary function of the script is to return all the child taxa of the specified parent taxa. The script has various options for what information is written in the output.
On first use, a small sqlite database will be created in your home directory by default change the location with the --database flag. You can update this database by using the --update flag. Note that if the database is not in your home directory, you must specify it with --database or a new database will be created in your home directory.
