Overview
TRANS-MNET available here implements the time series analysis of gene expression profiles
with the state space model. The current version (last modified; 07-Mar-2007) is executable
for Windows only and provided as an executable format. The source codes are written by C
language (Osamu Hirose).
The application software provides us an integrated analytic tool for time
course gene expression analysis. It contains a wide variety of applications
as follows:
-
Automatic extraction of genes relevant to temporal process of gene regulatory program.
-
Statistical identification of transcription modules of genes
-
Inference of temporal dependency between the estimated transcription modules (module interactions)
-
Statistical evaluation of temporal dependency between individual genes (gene-level interactions).
To view and summarize the results,
we recommend use of R
which is a free software environment for statistical computing and graphics.
This website also distributes a set of R scripts for accelerating summarization of
data analysis.
Figure 1: Time series analysis of gene expression profiles with TRANS-MNET
and a snapshot of graphical images which are created by R scripts that
we developed. The method explores the potential transcriptional modules
of genes which are relevant to the temporal gene expression program behind
time series gene expression profiles, and simultaneously, evaluates the
degree of connectivities across the overall genes.
