Standard browser functions are severely lacking for many applications. Specifically, they do not allow the user's query to span new lines, disregard white space or numbers. This is a problem for scientists who are looking for specific DNA sequences in large online databases. Given the size of the genomes we often look at, 6-7 billion basepairs, not only is it a hardship to have these limitations on your searches but it makes them almost worthless. If your sequence of interest crosses a new line boundary, a nucleotide numbering demarcation, or white space your search will fail to successfully locate your sequence.
To fix this problem we have created a Google Chrome extension called Sequence Finder. Sequence Finder allows the user to search through linebreaks, numbers, and whitespace allowing for an exhaustive search on the webpage itself. Sequence Finder highlights all instances of your sequence and it can navigate through different occurrences throughout the webpage with interactive arrow buttons. Sequence Finder is compatible with all major genome repositories including XenBase, NCBI and SGD. This changes the paradigm of having to export your data and analyze it elsewhere. This extension will both increase accuracy of identification for nucleic acid sequences and will also save massive amounts of time.
