Though general search engines can be tuned to accept ‘processed’ queries, the burden of preparing such ‘search strings’ simply defeats the purpose of quickly locating highly relevant information. Unlike ‘sequence similarity’ searches that employ dedicated algorithms (like BLAST) to compare an input sequence from defined databases, a direct ‘sequence based’ search simply locates quick and relevant information about a blunt piece of nucleotide or peptide sequence. This approach is particularly invaluable to all biomedical researchers who would often like to enter a sequence and quickly locate any pertinent information before proceeding to carry out detailed sequence alignment. Results: Here, we describe the theory and implementation of a web-based front-end for a search engine, like Google, which accepts sequence fragments and interactively retrieves a collection of highly relevant links and documents, in real-time. e.g. flat files like patent records, privately hosted sequence documents and regular databases. Conclusions: The importance of this simple yet highly relevant tool will be evident when with a little bit of tweaking, the tool can be engineered to carry out searches on all kinds of hosted documents in the World-Wide-Web.Availability: Instaseq is free web based service that can be accessed by visiting the following hyperlink on the WWWhttp://instaseq.georgetown.edu http://precedings.nature.com/documents/2492/version/1 Tue, 11 Nov 2008 20:14:41 UTC Searching the World-Wide-Web using nucleotide and peptide sequences hdl:10101/npre.2008.2492.1 2008-11-11 Natarajan Ganesan Nature Precedings 2008-11-11T20:14:41Z Manuscript Bioinformatics http://creativecommons.org/licenses/by/3.0/ http://precedings.nature.com/documents/2452/version/1 Written and spoken words activate left hemisphere areas involved in language processing. However, we here show that overlearned sequences (e.g. letters, numbers, weekdays, months) involve an unexpected right hemispheric activation in both the middle temporal gyrus and temporoparietal junction. Our findings offer a framework for understanding neuropsychological patterns seen in conditions such as synesthesia, in which anomalous perceptual experiences are triggered by overlearned sequences, and also in semantic dementia, in which left hemisphere damage disrupts word knowledge even while sequences can be spared. http://precedings.nature.com/documents/2452/version/1 Tue, 04 Nov 2008 17:33:42 UTC Why overlearned sequences are special: distinct neural networks in the right hemisphere for ordinal sequences hdl:10101/npre.2008.2452.1 2008-11-04 David M.
