Complementary source modulation

The remainder of this text will now focus on the complementary source modulation (CoSM) method of gas detection.

A Biopipe protocol represents a series of analyses. Each unit of analysis consists of specifications for input, analysis, and output. The input layer consists of a number of adaptors for various common database formats or for remote fetching from Web sources like GenBank. The role of the input layer is to retrieve data into a common format for a subsequent analysis. The complementary output layer contains adaptors to push the analysis result out to the desired database or format. The analysis layer functions through the action of wrapper Biopipe Perl modules that make standard Bioperl runnable binaries accessible to the Biopipe system. An explicit design goal of Biopipe is to reuse the encapsulations of binary tools, importers, and exporters that Bioperl already includes, with thin wrappers that specify the inputs that the input layer must provide in a workflow context. 

While behavioural and chemical programs are in progress, a further complementary approach to the study of any semiochemical system involves an examination of the semiochemical source and of factors which modulate that source s activity in ways which could be semiochemically significant (Adams, 1980).
