Aghermann -- a sleep research experiment manager and Achermann et al (1993)
aghermann [-l LOG_FILE
] [-n] [EXP_ROOT_DIR
is a 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
(plain EDF as well as EDF+C are supported). These recordings can then be
conveniently scored; scores can be imported/exported in plain ASCII. Scoring
can be outsourced to external scripts written in lua.
If run without arguments, your last session will be restored; an experiment
located in EXP_ROOT_DIR
will be selected otherwise.
With option -n
(and an EXP_ROOT_DIR
, which is non-optional in this
case), the experiment session in that directory will be initialised and
immediately closed, upon which Aghermann
will exit. No windows will be
open and no GTK+ code run; this option was implemented with the idea of
running the core structural part of Aghermann
With option -l LOG_FILE
, aghermann will write a log of its inner
workings to LOG_FILE
; if the latter is "-", stdout is used.
By default, (almost all) logging is suppressed.
For Aghermann to be able to manage an EDF file, all relevant fields in its
header must be filled out correctly, as follows:
- patient_id uniquely identifies the subject;
- recording_id identifies the recording session (out
of several other such sessions, each containing the same series of
episodes) and the individual episode. These two items must appear in one
of the following combinations:
- "Session : Episode"
- "Episode (Session)"
- recording_date and recording_time must not
overlap with other episodes in the same session and not be too far removed
from each other (more than 7 days).
- ~/.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.
