The idea of cognitive radios (CRs), which is a particular extension of software-defined radio that employs model-based reasoning about the channel, users, and communications context [1], was born out of the wireless spectrum's limitation.
Kriging and mapping were performed with the gstat package of the R software and the spatial analyst extension of ArcGIS software v.9.3 (ESRI Inc. Redlands, CA USA).
BOLD imaging data were analyzed using the Brain Voyager QX software (Brain Innovation, Maastricht, Holland); a plug-in extension of this software was used to compute the individual functional connectivity analyses.
Source code is provided to allow easy extension of the software.
To simplify the extension of the software with new tools, some portions of the GUI can be easily customized by Python programmers.
An additional planned extension of the software is the support of different compartment sizes (if multi-compartment models are analyzed) which is currently not the case.
A recent extension of the software allows tracking of the geographic location state along the phylogenetic tree, yielding posterior estimates of the location of each branch/node in the tree given the phylogenetic uncertainties [ 18].
So far, the most widely used method to detect outliers from AFLP genome scans is implemented in Dfdist, an extension of Fdist software that allows the use of dominant markers [ 7].
The expression data for the filtered probes of both miRNA (1,179 probes) and gene (55,681 probes) microarrays were normalized using quantile normalization, and were subjected to DE analyses using QPROT software (an extension of the QSPEC software for generic expression data with missing values).
In order to promote the advance in science many research groups are making their software development projects publicly available, as open-source software, which encourages researchers to develop extensions of verified software applications, like interfaces, packages or specific services.
