Applications

COPASI is a software application for simulation and analysis of biochemical networks and their dynamics.

COPASI is a stand-alone program that supports models in the SBML standard and can simulate their behavior using ODEs or Gillespie's stochastic simulation algorithm; arbitrary discrete events can be included in such simulations.

COPASI carries out several analyses of the network and its dynamics and has extensive support for parameter estimation and optimization. COPASI provides means to visualize data in customizable plots, histograms and animations of network diagrams.

MODELS Models in COPASI are based on reactions that convert a set of species into another set of species. Each species is located in a compartment, which is a physical location with a size (volume, area, etc). This maps directly to biochemical reaction networks, but can also represent other types of processes (for example, the species could be cell types). COPASI automatically converts the reaction network to a set of differential equations or to a system of stochastic reaction events — the user does not have to write down the math explicitly, the software does that.

Models can also have:

• * Unlimited number of species, reactions, and compartments.
• * Arbitrary discrete events; these can be used to change the model, or just to monitor the progress of simulations.
• * Arbitrary differential equations; these have to be added explicitly by the user and can be mapped to species, compartments, or generic variables.
• * Compartments can have variable sizes (ie they can be variables of the model).
• * The rates of reaction can be picked from a set of predefined kinetic functions (the most common in biochemistry), or arbitrary functions defined by the user.

Models can be visualized through

• * the GUI interface, with tables for reactions, species, compartments, etc.;
• * an arbitrary number of network diagrams (including an SBGN-compliant option);
• * the full set of differential equations; these can be exported in Latex or MathML formats.

COPASI can import and export models in the SBML format (levels 1 to 3). Models can also be exported in XPP format, Berkeley Madonna format, and as C code (in addition to MathML and Latex). SIMULATION Simulation can be performed either with stochastic kinetics or with differential equations, and the software easily allows switching between them. The software provides an interface to create parameter scans (sweeps), parameter sampling and repeated simulations — including complex simulation scenarios mixing parameter samples with scans and repeats of simulations (or other analyses).

Algorithms available for simulation:

• * LSODAR for ordinary differential equation modeling.
• * Gillespie's direct method for exact stochastic kinetics.
• * Gibson-Brooke's version of Gillespie's algorithm for exact stochastic kinetics.
• * τ-leap algorithm for faster (approximate) stochastic kinetics.
• * Adaptive SSA/τ-leap algorithm for faster (approximate) stochastic kinetics.
• * Hybrid Runge-Kutta/SSA for hybrid simulations with stochastic kinetics and differential equations.
• * Hybrid LSODA/SSA for hybrid simulations with stochastic kinetics and differential equations.

Simulations can be of time courses or steady states. ANALISYS Models can be analyzed and modified with a large set of methods:

• * Stoichiometric analysis of the reaction network, including mass conservation analysis and elementary flux modes.
• * Optimization of arbitrary components of the model using a range of diverse algorithms.
• * Parameter estimation using a range of diverse optimization algorithms. This can be done over several different experiments simultaneously, including mixtures of steady-state and time course experiments.
• * Local sensitivity analysis.
• * Metabolic control analysis (a special form of sensitivity analysis).
• * Time scale separation analysis; this allows definition of fast and slow components of the model, in a time-dependent way.
• * Analysis of stochasticity using the linear noise approximation (allows estimating variances and co-variances even in the presence of large numbers of particles).
• * Cross sections, which allow to characterize non-linear dynamics properties, such as oscillations and chaos.
• * Lyapunov exponents, which allows to establish if the system dynamics are chaotic.

DATA VISUALIZATION COPASI allows users to visualize data in various ways:

• * Network diagrams can be used to visualize time course simulations as movies;
• * Network diagrams can also be used to visualize mass conservation moieties, and elementary flux modes;
• * Arbitrary 2D plots of any model variables and parameters (including trajectories in phase space);
• * A series of plots that are most commonly used are already pre-defined;
• * Color-coded matrices, for easily identifying large and small values;
• * 3D bar chart representation of matrices

DATA OUTPUT COPASI allows users to define report files where data is written to during simulations and analyses. These report files are useful for importing data onto other applications for further analysis and visualization.

"Cube" (CUBE Uniform Behavioral Encoding) is a presentation component suitable for displaying a wide variety of performance data for parallel programs including MPI and OpenMP applications.

Program performance is represented in a multi-dimensional space including various program and system resources. The tool allows the interactive exploration of this space in a scalable fashion and browsing the different kinds of performance behavior with ease. All metrics are uniformly accommodated in the same display and thus provide the ability to easily compare the effects of different kinds of program behavior.

"Cube" also includes a library to read and write performance data as well as operators to compare, integrate, and summarize data from different experiments.

Linsim is designed to read and then add path simulation to any monophonic wav file recorded at any sampling rate. It works particularly well with files that were created using fldigi’s audio capture and audio generate functions. The entire wav file will be saved to computer memory and then duplicated during the signal processing. The user should try to keep the length of the wav file at 20 Mg or less, but the author has tested some 200 Mg files on both Linux and Windows-8 without causing a program fault. These files were original VOAR broadcasts of about 30 minutes duration. The objective of this type of simulation is to finally measure the character error rate (CER) and bit error rate (BER) of a specific modem type and decoder design. For most modems a sequence of 1000 characters provides a sufficient level of confidence in the CER measurment.

Raspberry Pi Imager downloads a .JSON file from the Raspberry Pi website with a list of all current download options, ensuring you are always installing the most up-to-date version.

Once you’ve selected an operating system from the available options, the utility reads the relevant file directly from the Raspberry Pi website and writes it straight to the SD card. This speeds up the process quite considerably compared to the standard process of reading it from the website, writing it to a file on your hard drive, and then, as a separate step, reading it back from the hard drive and writing it to the SD card.

During this process, Raspberry Pi Imager also caches the downloaded operating system image – that is to say, it saves a local copy on your computer, so you can program additional SD cards without having to download the file again.
