Changes in the 'Usage' and 'Overview' pages (February 20, 2009)
The usage of PseudoViewr web application for any systems is now available at 'Usage of web application for any systems' page.
Due to the change in the layout style of PsudoViewer, the 'Overview' page has been updated. - go Overview

Changes in the input formats and examples (September 24, 2008)
- '.bpseq' and '.ct' files can be used in the new version of PseudoViewer web application for any systems. - go PseudoViewer web application for any systems
- Examples of large scale structures, which are 16s rRNA structures with pseudoknots and over 1500 bases, are updated. The structure data of these structures are from Comparative RNA Web (CRW) Site (http://www.rna.ccbb.utexas.edu/). - go examples

PseudoViewer quick link (July 26, 2008)
PseudoViewer web service can be accessed by using a simple get request.
The quick link page is http://pseudoviewer.inha.ac.kr/WSPV_quickSender.asp
The get values of a structure (as 'str') and a seuqnece (as 'seq') are required. the start base number (as 'start') is optional. the start base number can be added in front of the sequence.
For example (change red and blue parts of the examples as your input data),
Query 1 :
      http://pseudoviewer.inha.ac.kr/WSPV_quickSender.asp?seq=CCUUACCUCGGGUAGAGGCCCA&str=(((..[[[[)))..]]]]....
Query 2 (with start base number):
      http://pseudoviewer.inha.ac.kr/WSPV_quickSender.asp?seq=CCUUACCUCGGGUAGAGGCCCA&str=(((..[[[[)))..]]]]....&start=342
Query 3 (same result as Query 2):
      http://pseudoviewer.inha.ac.kr/WSPV_quickSender.asp?seq=342CCUUACCUCGGGUAGAGGCCCA&str=(((..[[[[)))..]]]]....
Query 4 (omitted sequence):
      http://pseudoviewer.inha.ac.kr/WSPV_quickSender.asp?seq=342CCUUACCUCGGGUAGAG459GCCCA&str=(((..[[[[)))..]]]]....

PseudoViewer web service (February 01, 2006)
We present a web service and web application of PseudoViewer as well as a new visualization algorithm. Users can visualize large-scale RNA secondary structures with pseudoknots of any type from any web browser and any operating system.
- go PseudoViewer web application for any systems
- go Usage of web application
- go Examples
The PseudoViewer web service can be integrated into other systems to visualize RNA structures. Since the PseudoViewer web service runs by exchanging XML based SOAP messages, a system developed in any programming language can use the service. Sample clients written in C# and Java can be downloaded from the web service developer'guide and download page

Changes in usage and bug fix (February 15,2005)
The input data format is expanded to handle multiple sequences - go Usage
Numbering position can be edited. - go Usage
Some bugs in the input format are fixed.

Release of PseudoViewer version 2.5 (July 06, 2004)
PseudoViewer version 2.5 improves PseudoViewer2 in the following ways:
Its algorithm is more general and powerful, in that it can visualize with fewer support lines pseudoknots with any number of stems in crossing relation to one another, as well as what we call twisted H-type pseudoknots. - go Examples
It automatically identifies the topological relation of the stems, such as adjacency, crossing, and inclusion, and visualizes the relation, which is very useful for analyzing and predicting RNA structures and classifying RNA pseudoknots.- go Usage
The input data format is expanded to handle incomplete or minimum structure data. - go Usage
PseudoViewer2.5 allows tertiary interactions other than pseudoknots in the input data, and visualizes them. - go Examples
Support lines between adjacent bases outside a pseudoknot are represented as curved lines instead of straight lines to increase the readability of the structure by reducing edge crossings. - go Examples
The user interface has been improved, including the development of editing facilities for the structure data and structure drawings. - go Usage

topological relation window (July 06, 2004)
PseudoViewer2.5 automatically identifies the topological relation of the stems, such as adjacency, crossing, and inclusion, and visualizes the relation in the topological relation window. It is useful for analyzing and predicting RNA structures and classifying RNA pseudoknots. - go Usage

Changes in the popup menu of the structure drawing and the structure data windows (March 25, 2004)
'Undo' and 'Redo' functions are added to the popup menu of the structure drawing window.
- go Usage
Several editing functions such as copy, paste, undo, and selectAll are added to the popup menu of the structure data window. - go Usage

Changes in file menu and draw option (September 02, 2003)
File->Open selection - go Usage
DrawOption->Base numbering, Additional line. - go Usage

Pseudoknot types that can be visualized by PseudoViewer2 have been expanded. (September 01, 2003)
PseudoViewer2 can now visualize pseudoknots of nontypical type such as trans-acting delta ribozyme and Hepatitis delta virus. - go Examples

Changes in the input format and the structure data editor (March 22, 2003)
PseudoViewer2 takes as input an RNA sequence with its structure data in bracket view, which is widely used for representing pseudoknots. - go Usage

PseudoViewer version 2.0 was developed. (January 20, 2003)
