Overview

The Cell System Markup Language (CSML) is an XML format for modeling, visualizing and simulating biopathways. CSML supports to represent several pathway types including metabolic, signaling, and genetic regulatory pathways. This project aims to facilitate the exchange of biopathway data in different formats. Effort has been made for data conversion from other XML formats. In addition, to allow extensible and flexible features of CSML, the Cell System Ontology (CSO) has been developed.

Prof. Chaouiya visited Miyano Lab

Chaouiya-san

Prof. Claudine Chaouiya first visited Miyano Lab in Sep. 9, 2010. We discussed about the application of Petri net to the field of Systems biology. Prof. Chaouiya gave the presentation about her group's recent research, for example, the analysis by using logical model, model checking and so on.

Prof. Chaouiya and Chen Li are the members of Program Committee of the Workshop on Biological Processes and Petri Nets (BioPPN2011). BioPPN2011 is the satellite workshop of PETRI NET 2011 and ASCD 2011, which will be held in June 20-24, 2010, Kanazawa, Japan. We encourage submissions of your inspired contributions relating to all aspects of the application and theory of Petri nets to Systems biology. Program of BioPPN2010 can be accessed from the website for your consideration.

Mini-Genome Square 2009 in Fukuoka, Japan

minigsquare

Li, Saito, Fujita, and Chalkidis attended the event "Mini-Genome Square 2009" at ELGALA Hall, in Fukuoka, December 20, 2009, which was organized by the Ministry of Education, Culture, Sports, Science and Technology specific area research. Many visitors have participated this event. The genome researchers explained their research together with actual living organisms, DNA, experimental machine and computers in an easy-to-understand manner.

We gave the explanation and answered the questions and doubts in this event. The title is "To understand bio-simulation from spot different game - health and disease".
