<div style="text-align: center;"><a href="http://cbil.upenn.edu/cgi-bin/tess/tess/"><b>http://cbil.upenn.edu/cgi-bin/tess/tess/ </b></a></div>TESS is a web tool for predicting transcription factor binding sites in DNA sequences. It can identify binding sites using site or consensus strings and positional weight matrices from the TRANSFAC, JASPAR, IMD, and our CBIL-GibbsMat database. You can use TESS to search a <b>few of your own sequences</b> or for user-defined CRMs <b>genome-wide</b> near genes throughout genomes of interest.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2452637064053403492.post-48415511219757739262008-10-19T12:00:00.000-07:002008-10-19T12:02:02.714-07:00RepeatMasker<div class="separator" style="clear: both; text-align: center;"><a href="http://www.repeatmasker.org/images/isb_logo.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://www.repeatmasker.org/images/isb_logo.gif" /></a> </div><div class="separator" style="clear: both; text-align: center;"><span>RepeatMasker</span></div><div style="text-align: left;"><span> </span>RepeatMasker <a href="http://www.repeatmasker.org/">http://www.repeatmasker.org/</a> is a program that screens DNA sequences for interspersed repeats and low complexity DNA sequences. The output of the program is a detailed annotation of the repeats that are present in the query sequence as well as a modified version of the query sequence in which all the annotated repeats have been masked (default: replaced by Ns). On average, almost 50% of a human genomic DNA sequence currently will be masked by the program. Sequence comparisons in RepeatMasker are performed by the program cross_match, an efficient implementation of the Smith-Waterman-Gotoh algorithm developed by Phil Green. <span> </span></div><div class="separator" style="clear: both; text-align: center;"> </div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2452637064053403492.post-59539641000356253252008-10-19T11:58:00.000-07:002008-10-19T11:59:23.340-07:00Gene Regulatory Information Server (AGRIS)<div class="separator" style="clear: both; text-align: center;"><a href="http://arabidopsis.med.ohio-state.edu/images/header.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="46" src="http://arabidopsis.med.ohio-state.edu/images/header.gif" width="420" /></a></div><br />

<div style="text-align: center;"><b>http://genome.ucsc.edu </b></div>The Genome Browser stacks annotation tracks beneath genome coordinate positions, allowing rapid visual correlation of different types of information. The user can look at a whole chromosome to get a feel for gene density, open a specific cytogenetic band to see a positionally mapped disease gene candidate, or zoom in to a particular gene to view its spliced ESTs and possible alternative splicing. The Genome Browser itself does not draw conclusions; rather, it collates all relevant information in one location, leaving the exploration and interpretation to the user. <br />
The Genome Browser supports text and sequence based searches that provide quick, precise access to any region of specific interest. Secondary links from individual entries within annotation tracks lead to sequence details and supplementary off-site databases. To control information overload, tracks need not be displayed in full. Tracks can be hidden, collapsed into a condensed or single-line display, or filtered according to the user's criteria. Zooming and scrolling controls help to narrow or broaden the displayed chromosomal range to focus on the exact region of interest. Clicking on an individual item within a track opens a details page containing a summary of properties and links to off-site repositories such as PubMed, GenBank, Entrez, and OMIM. The page provides item-specific information on position, cytoband, strand, data source, and encoded protein, mRNA, genomic sequence and alignment, as appropriate to the nature of the track.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2452637064053403492.post-85876623183378727562008-10-17T02:00:00.000-07:002008-10-17T03:38:13.673-07:00BioEdit Software<div class="separator" style="clear: both; text-align: center;"><a href="http://www.mbio.ncsu.edu/BioEdit/bioIcon2.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img src="http://www.mbio.ncsu.edu/BioEdit/bioIcon2.gif" border="0" height="91" width="200" /></a></div><br /><br /><br /><b><i><span style="color:red;"><span>BioEdit </span></span></i></b><span>is a biological sequence software written for Windows 95/98/NT/2000/XP.
