| Title: | Transcriptional analysis based on transcriptograms |
|---|---|
| Description: | R package for transcriptional analysis based on transcriptograms, a method to analyze transcriptomes that projects expression values on a set of ordered proteins, arranged such that the probability that gene products participate in the same metabolic pathway exponentially decreases with the increase of the distance between two proteins of the ordering. Transcriptograms are, hence, genome wide gene expression profiles that provide a global view for the cellular metabolism, while indicating gene sets whose expressions are altered. |

If species is a character, this method uses the biomaRt package
to build a Protein2GO list, if species is a data.frame, it will be used
instead.
The Protein2GO list will be used with the
topGO package to detect the most significant terms of each cluster
present in the DE slot of the object.

This method uses the limma package to identify which genes are
differentially expressed,
meeting the pValue requirement, for the contrast "case-control".
The levels lenght must be
equal to the number of samples present in the transcriptogramS2 slot of
the object, and its contents
is related to the order that the samples appear. FALSE must be used to
indicate case samples,
and TRUE to indicate control samples. If species is NULL, no
translation will be done, if species is a character,
the biomaRt package will be used to translate the ENSEMBL
Peptide ID to Symbol
(Gene Name), and if species is a data.frame, it will be used
instead.
If the translation fail for some protein, its ENSEMBL
Peptide ID will be present
into the Symbol column. This method also groups the differentially expressed proteins detected
in clusters, and plots a graphical representation of this clustering.

An integer number, referring to the number of processing cores to be used; or a logical value, TRUE indicating that all processing cores should be used, and FALSE indicating the use of just one processing core. The default value of this argument is 1. |
Connectivity/degree of a node is the number of edges it presents. A triangle of a node represents a pair of connected neighbors, the number of triangles on the adjacency list of a node is required to calculate its clustering coefficient. The clustering coefficient of a node measures, in the interval [0, 1], the likelihood that any two of its neighbors are themselves connected, this is calculated by the ratio between the number of triangles that the node has, and the maximum possible number of edges on its cluster (nodeTriangles / (nodeDegree * (nodeDegree - 1) / 2)). The window connectivity is the average connectivity calculated over the window. The window clustering coefficient, a value in the interval [0, 1], is the average clustering coefficient calculated over the window. The window modularity, a value in the interval [0, 1], is defined as the ratio between the total number of edges between any two nodes of the window, and the sum of the degrees of the nodes presents in the window. The window considers periodic boundary conditions to deal with proteins near the ends of the ordering.
This method returns a data.frame containing: ENSEMBL Peptide ID, its position on the ordering, node degree, number of triangles and clustering coefficient, and window connectivity, clustering coefficient and modularity.

For each transcriptome sample, this method assigns to each protein the
average of the expression values of all the identifiers related to
it. It is necessary a
dictionary to map the identifiers to proteins.
