NAME

	    Aghermann -- a sleep research experiment manager and Achermann et al (1993) model simulator

SYNOPSIS

	    aghermann [exp_root_dir]

DESCRIPTION

       Aghermann is GTK+ program designed to run Process S simulations on Slow-Wave Activity profiles from EEG recordings as outlined in Achermann
       et al (1993).  In this capacity, Aghermann produces a set of sleep homeostat parameters which can be used  to  describe	and  differentiate
       individual sleepers, such as short vs long sleepers, early vs late, etc.

       Also  provided  are  general-purpose facilities for displaying EEG and accompanying recordings, such as EOG and EMG, saved in EDF (European
       Data Format) files.  These recordings can then be conveniently scored; scores can be imported/exported in plain ASCII.  For the particulars
       of how Aghermann treats the various fields, see edfhed(1).

       If run without arguments, your last session will be restored; an experiment located in exp_root_dir will be selected otherwise.

FILES

       ~/.config/aghermann/sessionrc, contains a list of paths to recent experiment trees.

       ./.agherman.conf and ./.expdesign.conf, saved settings of the experiment located in
	      this tree.

       The  project's git repository is kept on sf.net and also on github.com; more details on the Achermann model as well as on usage and project
       background can be found at http://johnhommer.com/academic/code/aghermann.  Locally, please refer to /usr/share/doc/aghermann/README[.gz].

NAME

       gpiv_scale - Scaling of PIV data.

SYNOPSIS

       gpiv_scale [-h | --help] [-p | --print] [-s M |-S M] [-t dT |-T dT] [-v | --version] [-zp x0 y0] [-zv x0 y0] [filename] < stdin > stdout

DESCRIPTION

       gpiv_scale  applies  the  image	magnification and the time between successive recordings to the PIV estimators. This results that particle
       displacements [px] are modified to velocities [m/s] and their positions from [px] to [m]. A physical reference for the positions of the PIV
       data can be applied by means of the image zero-offset option.

       If  filename  is used, the parameters and options to be used for gpiv_scale are subsequently read from the image header (filename.h in case
       of raw binary images) or from the configuration resources (containing the IMG and POST keys). The parameters may be overruled by  the  com-
       mand line options, as explained below.

Options
       -h | --help
	      On-line help.

       -p | --print
	      Prints parameters, command line options and input and output filenames to stdout.  The output is identic of filename.par, in case -f
	      is used.

       -s M   spatial scaling with magnification factor M [m/px]

       -S M   Inverse spatial scaling with magnification factor M [m/px]; returns scaled data to their original magnitudes.

       -v | --version
	      Prints version information on standard output, then exits successfully.

       -t dT  Translates particle displacements into velocities by devising them with the time between subsequent recordings dT [s].

       -T dT  Inverse time scaling. Returns velocities into displacements [px]

       [-z x0 y0]
	      Relates the positions of the observations of velocities/displacements to a physical location in the experiment by image zero offset-
	      ting. x0 y0 denote the physical position of pixel (0,0) in the image.

       filename
	      Input PIV file. Overrides stdin and stdout. The output will be written to filename.sc.piv. Parameters are stored in filename.par and
	      may be used for future use by including them in ./gpivrc.

BUGS

       The program has been tested for PIV data. So far, no bugs have been found.
