Similar to IGV, the workbench provides a scrollable view of a genome and or sequence as well as compatibility with a large number of file formats and is supported on many different operating systems. Although there is overlap between many of these tools insofar as their capability, each has a particular niche it fills. IGV is an empty box useful for scientists to view annotated sequences and genomes, as well as read mapping.
Lastly, JBrowse and GBrowse accomplish the task which is difficult but not impossible to do with the other tools: that is to share an annotated sequence or genome across a group.
While the above four tools are popular to use, there are other genome browsers not listed but worth trying out. My experience is less than ideal, but everyone's mileage may very. These include:. JBrowse JBrowse is a genome browser written in javascript for viewing genomes within a web browser. Conclusions Although there is overlap between many of these tools insofar as their capability, each has a particular niche it fills. More Options While the above four tools are popular to use, there are other genome browsers not listed but worth trying out.
Relative to the three applications above, I've personally found it's user interface a bit harder to use for example, a vertical scroll bar to zoom.
Privacy policy Copyright Links Sitemap. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available.
They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc.
They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There are numerous tools to browse genomes. This article focuses solely on standalone desktop genome browsers.
When users load a new dataset or open a file, the new data appear in labeled tracks. Users can click-drag track labels to move tracks to new locations. Right- or control-clicking a track label activates a popup menu with multiple options. One option Make Annotation Depth Graph creates a new genome graph summarizing the number of annotations covering each base position, which users can save to a file Fig. Visualizing ESTs and tiling array data. ESTs blue are from a sequencing experiment Weber et al.
Data are from Arabidopsis seedlings. IGB supports dynamic zooming and panning through a genome, allowing users to navigate easily through a genome at multiple scales. Zooming focuses on the user's last click, indicated by a vertical stripe in the display. During zooming, the zoom stripe remains stationary as flanking regions expand or contract in an animated fashion as users operate the zoom controls.
The zoom stripe provides a base pair pointer in close-up views for inspecting residues at feature boundaries. The display contains several tabbed control panels and users can move into new windows using the View menu. The Graph Adjuster panel lets the users to fine-tune a graph's appearance and adjust the range of values it displays.
It also offers options to add or subtract graphs from each other, providing a first-pass visual assessment of differential expression across sample types. A literature survey identified 70 articles that used IGB in diverse applications, including transcription factor binding site discovery Kim et al.
