![]() They are able to influence the synthesis of many proteins or even those involved in entire pathways, making them important molecules in harmonised regulation. Upon binding miRNAs either repress translation or cleave the mRNA sequence. miRNAs are small, non-coding RNA molecules that bind to miRNA-target regions in the mRNA. They either activate or repress transcription. TFs are proteins that bind to a specific DNA sequence, i.e., the transcription factor binding site (TFBS). Whereas gene expression is influenced by epigenetic factors and/or transcription factor (TF) binding, protein synthesis can be regulated by microRNAs (miRNAs). Regulation of gene expression, protein synthesis and activity occurs at different levels. ![]() These processes contain genes, proteins and/or metabolites, their molecular interactions and reactions, but little regulatory information is present. Many known biological processes are represented in various online repositories, like WikiPathways and Reactome. It still remains a challenge to combine the new insights with existing knowledge and to understand the regulation of biological processes in detail. Recently, the ENCODE project, whose main goal was to identify all the functional elements in the human genome sequence, revealed novel insights in genetic regulation. However, understanding of the regulation of gene expression, protein synthesis and activity is far from complete. Approximately 25,000 gene coding regions were defined.

Which occurred when missing value treatment was set to pairwise_omit. **WARNING:** A serious bug was spotted in Jean-Sebastien Lerat's Spearman implementation, logging level can now be adjusted (defaults to fatal to reduce size of log file) network comment does no longer list removed edges and filtered rows, to reduce size of big networks fixed rarefaction bug (previously, error message prevented to carry out rarefaction) improved taxonomy parsing from biom files (hit number is parsed if provided) if groups are provided, the group properties are listed when matrix info is selected fixed problem of setting initial edge selection parameter from settings file treatment of ties in Spearman implementation fixed change of license (from 22nd May 2014 onwards, CoNet is distributed under the GNU General Public License version 2) command line tool for the analysis of large data sets repeatable data analysis with settings loading and saving several data preprocessing and filtering options supports row groups and combination of 2 input matrices significance can be tested with various randomization routines and multiple testing corrections ![]() implements the ReBoot procedure (also implemented in R package ccrepe) measures can be combined in multiple ways large choice of correlation, distance and similarity measures automatic assignment of higher-level taxa from lineages support for lagged similarity computation in time series It has been designed with (microbial) ecological data in mind, but can be applied in general to infer relationships between objects observed in different samples (for example between genes present or absent across organisms). CoNet detects significant non-random patterns of co-occurrence (copresence and mutual exclusion) in incidence and abundance data.
