The psignifit engine source code can be compiled to run as a command-line executable. On the UNIX or DOS command line, it can receive its input through stdin or through named files, in the manner of most command-line utilities. Under Classic MacOS, the utility takes all its input from a text file called "prefs" in its own directory. On the download page, you can download the standalone utility, ready compiled for various platforms. The archive contains:
On MacOS 9.x and below, the flexibility of the standalone application is limited. All its input comes from a text document called "prefs" in the application folder. Edit the "prefs" document, then simply double-click on the application to run.
On Windows, the flexibility of the standalone is limited simply because the flexibility of the command-line is limited. It is highly recommded that you download Cygwin, and then use a Cygwin-compiled version of psignifit under the bash or tcsh shells.
As a command-line executable, psignifit can accept input in a number of different ways:
See the enclosed help documents for an explanation of the preferences format, a list of available options and a glossary of common terms. Note in particular the #WRITE_... options described in psych_options.txt), which allow different parts of the output to be redirected to named files, or to the standard output. If no #WRITE_... options are specified, then certain matrices are printed to stdout by default - this is the output you will probably see the first time you run the utility, and the parts you are most likely to be interested in are the TH_LIMS and SL_LIMS matrices, whose format is as follows:
