Sequerome is a web-based Sequence profiling tool
Sequence profiling tool
A sequence profiling tool in bioinformatics is a type of software that presents information related to a genetic sequence, gene name, or keyword input. Such tools generally take a query such as a DNA, RNA, or protein sequence or ‘keyword’ and search one or more databases for information related to...

The software application can be accessed directly. The homepage shows three panels: Query pane, Results pane and the Search History pane. The user may resize these panes to perform parallel actions in any of these panes. In a single browser it is possible to run parallel BLAST

Alternatively the user can also perform a variety of other actions including Sequence manipulation, analysis, and alignment using existing tools available in the web. The One-box any-sequence, takes input in any format (FASTA, with or without spaces/numbers...). Alerts also exist to warn wrong selection of choices (DNA/RNA/Protein). Results obtained from 'sequence manipulation' e.g. translation, can be further carried on to do further BLAST

Search History Pane

One of the key features of a profiling an input sequence data is to store, retrieve and effectively combine and re-use the older inputs. These can be further enhanced if there is retrieval options for each of the operations performed. The bottom right panel in the browser does this while also storing all the input sequences entered earlier. Thus the browser lends an environment to carry out tabbed browsing.. For each of the icons linking to the stored results, the user has a choice of archiving them, including print, save and mail options. These can be seen as small colored pictures on top of each icon.
