Flux Activity Analysis

This process is used to analyse the activities of fluxes in a collection of flux vectors. A flux is considered to be inactive if it equals zero and active otherwise. For each vector of fluxes supplied to this process, the number of active and inactive fluxes will be written to a specified output file.

Here is the set of keywords this process understands, along with a description of their possible corresponding values. See the command line documentation for more information about keyword-value pairs.


Required Keywords Possible Values
Process FBA Flux Activity Analysis
Reaction File The name of an FBA Reaction File containing a stoichiometric network.
Flux Vector File The name of a text file containing the flux vectors whose activities are to be analyzed. See Multiple-Flux Vectors Files for further information.
Flux Vector File Format The format of the specified flux vector file. See File Formats for further information.
Zero Cutoff The amount by which fluxes can differ from zero, but still be considered equal to zero. See Zero Cutoffs for further information.
Activity Count File Name The desired name of the file to which the number of active and inactive fluxes in each vector will be written. The i-th line in this file corresponds to the i-th flux vector in the input file.
