| Abstract | With the rapid advancements in our data acquisition capabilities and the increased availability of gene interaction databases a variety of pathway analysis tools have been proposed. However, all these methods are dependent on the quality of the available pathways. These pathways were designed to describe the general mechanism of a particular disease or biological process. The known pathways encompass the results of many biological experiments and even though they represent our current understanding of those particular biological processes, they are still generally considered sketchy and incomplete. One piece of information that is generally missing regards the role or importance of a gene in a given pathway which we refer to as the gene contribution. We propose here a method, based on genetic algorithms, to objectively quantify the contribution of each gene. Using a pool of 24 data sets from 12 different conditions divided in train and test groups, we show how an impact pathway analysis method achieves significantly better results with the newly estimated gene contributions when compared with both the initial default contributions, as well as randomly selected gene contributions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
