101 What it does
|
|
|
102 -------------
|
|
|
103
|
|
|
104 This tool generates flux samples starting from a model in JSON or XML format by using CBS (Corner-based sampling) or OPTGP (Improved Artificial Centering Hit-and-Run sampler) sampling algorithms.
|
|
|
105
|
|
|
106 It can return sampled fluxes by appliying summary statistics:
|
|
|
107 - mean
|
|
|
108 - median
|
|
|
109 - quantiles (0.25, 0.50, 0.75).
|
|
|
110
|
|
|
111 Flux analysis can be perfomed over the metabolic model:
|
|
|
112 - parsimoniuos-FBA (optimized by Biomass)
|
|
|
113 - FVA
|
|
|
114 - Biomass sensitivity analysis (single reaction knock-out). It is the ratio between the optimal of the Biomass reaction computed by FBA after knocking-out a reaction and the same over the complete model.
|
|
|
115
|
|
|
116 Accepted files:
|
|
|
117 - A model: JSON or XML file reporting reactions and rules contained in the model. It can be ENGRO2 or a custom model.
|
|
|
118 - Context-specific bounds: generated by RAS to Bounds tool. This can be a collection of bounds too (one bounds file per context).
|
|
|
119
|
|
|
120 Output:
|
|
|
121 -------------
|
|
|
122
|
|
|
123 The tool generates:
|
|
|
124 - Samples: reporting the sampled fluxes for each reaction (reaction names on the rows and sample names on the columns). Format: tab-separated.
|
|
|
125 - a log file (.txt).
|
|
|
126
|
|
|
127 **TIP**: The Batches parameter is useful to mantain in memory just a batch of samples at time. For example, if you wish to sample 10.000 points, than it is suggested to select n_samples = 1.000 and n_batches=10.
|
|
|
128 **TIP**: The Thinning parameter of the OPTGP algorithm is useful to converge to a stationary distribution (see cited articles by Galuzzi, Milazzo and Damiani).
