Matlab is a programming language for general scientific computing, well-adapted to the rapid prototyping of new algorithms. Neuroimaging pipelines can be implemented as a Matlab script, e.g., DPARSF (Chao-Gan and Yu-Feng, 2010), fMRIstat 1 (Worsley et al., 2002), SPM 2 (Ashburner, 2011), or brainstorm 3 (Tadel et al., 2011). The analysis of a neuroimaging database typically involves a large number of inter-connected processing steps, collectively referred to as a pipeline (or workflow) (Deelman et al., 2009). The rapid development of public databases in neuroimaging (e.g., Evans, 2006 Biswal et al., 2010 Burton, 2011) is opening exciting avenues for data mining. The benchmark results showed that PSOM is a powerful solution for the analysis of large databases using local or distributed computing resources. We ran several benchmark experiments on a public database including 200 subjects, using a pipeline for the preprocessing of functional magnetic resonance images (fMRI).

The package has no external dependencies besides Matlab or Octave, is straightforward to install and supports of variety of operating systems (Linux, Windows, Mac).

PSOM is distributed under an open-source MIT license and can be used without restriction for academic or commercial projects. The PSOM execution engine provides a number of automated services: (1) it executes jobs in parallel on a local computing facility as long as the dependencies between jobs allow for it and sufficient resources are available (2) it generates a comprehensive record of the pipeline stages and the history of execution, which is detailed enough to fully reproduce the analysis (3) if an analysis is started multiple times, it executes only the parts of the pipeline that need to be reprocessed. All steps of analysis are instead described by a regular Matlab data structure, documenting their associated command and options, as well as their input, output, and cleaned-up files. PSOM does not introduce new language constructs to specify the steps and structure of the workflow. The pipeline system for Octave and Matlab (PSOM) is a flexible framework for the implementation of pipelines in the form of Octave or Matlab scripts. Sqwave = -abs(saw)./(saw+sawzeros) %.The analysis of neuroimaging databases typically involves a large number of inter-connected steps called a pipeline. Sawzeros = (saw = zeros(size(saw))) %elminates division by zero in next step Saw = 2*mod(x, wavelength)/wavelength-1 %start with sawtooth wave You might want to consider why the mathematical shortcuts in these programs produced the desired waveforms.įunction saw = sawtooth(freq, samplerate)įunction sqwave = squarewave(freq, samplerate)
To create your own sawtooth, square, or triangle wave in Octave, you can use the Octave programs below. There is no square or sawtooth function in Octave. Then you can play the sound with your favorite media player. You also can use a wavwrite function (which exists in both MATLAB and Octave) to write the audio data to an external file. To play the sound, you need to use the play sound function rather than wavplay. The linspace function is the same in Octave as in MATLAB. The fplot function is the same in Octave as in MATLAB except that for colors, you must put a digit from 0 to 7 in single quotes rather than use the name of the color. If you try to do the above exercise in Octave, most of the functions are the same.

There are versions of Octave for Linux, UNIX, Windows, and Mac OS X. It has many but not all of the functions of MATLAB. Octave is a freeware, open-source version of MATLAB distributed by GNU.
