What it does
-------------

This tool generates flux samples starting from metabolic models using CBS (Corner-based sampling) or OPTGP (Improved Artificial Centering Hit-and-Run sampler) algorithms.

Two upload modes are supported:
1. **Model + bounds**: Upload one base model and multiple bound files (one per context/cell type)
2. **Multiple complete models**: Upload multiple complete model files, each with integrated bounds

It can return sampled fluxes by applying summary statistics: 
   - mean
   - median
   - quantiles (0.25, 0.50, 0.75)

Flux analysis can be performed over the metabolic model by using the objective function already set in the model. The following analyses are supported:
   - parsimonious-FBA (optimized by Biomass)
   - FVA (with configurable optimality percentage)
   - Biomass sensitivity analysis (single reaction knock-out)

Output:
-------------

The tool generates:
   - Samples: reporting the sampled fluxes for each reaction (reaction names on the rows and sample names on the columns). Format: tab-separated.
   - a log file (.txt).

**TIP**: Bounds generated by RAStoBound are grouped in a collection. You can select collections by clicking on "Dataset Collection" option in the "Bound file(s):" input parameter.

**TIP**: The Batches parameter helps maintain memory efficiency. For 10,000 samples, use n_samples=1,000 and n_batches=10.

**TIP**: The Thinning parameter for OPTGP helps converge to stationary distribution.

**TIP**: FVA optimality percentage allows you to explore suboptimal flux ranges. 100% restricts to optimal solutions, while lower values (e.g., 90%) allow broader flux ranges.
