This help file contains a brief introduction to waves+ operations anda list of waves+ global parameters and commands.  For more information, see the full waves+ man page.  To do so, run "eman waves+" in ashelltool window or, if you are using X Windows, click on the "waves+ manual" button in the control panel.WAVES+ STARTUP==============Waves+ starts up with the following steps: (1) It checks to see if any optional DSP board is installed (by tryingto open /dev/dsp32).  If a board is found, waves+ will use it forspectrograms and speech output, and all FEA_SD files will be read inas SHORTs.  If no board is found, waves+ will use external ESPSprograms for spectrogram computation and speech output, and it willnot transform the type of FEA_SD files.  (2) It reads global parameter settings from a startup file.  The fileis (in order of precedence) (a) whatever is specified by the -woption; (b) the file .wave_pro in your home directory; or (c)$ESPS_BASE/lib/waves/.wave_pro.  Any file specified by -w or in theprofile is searched for on the path "$HOME:$ESPS_BASE/lib/waves/.wave_pro".The search path used can be overriden by setting the unix environment variableWAVES_PROFILE_PATH before starting xwaves+.(3) It processes whatever signal or command files may be listed on thecommand line.WAVES+ CONTROL PANEL====================The values of panel items ending with a colon may be modified by leftmousing (to activate the item) followed by text or numeric input.  Use<delete> to delete the previous character entered and <CTRL-u> toremove the entire line.  Any new or changed value must be "entered"(while activated) by hitting the return key.  The "PAUSE", "CONTINUE,""QUIT!," "HELP!", and "waves+ manual" items perform the correspondingfunctions immediately when moused.  Here are brief explanations of thepanel items.  For details, see the man page. INPUTfile:       The relative or absolute pathname of a signal to be      displayed.  A search path ".:$ESPS_BASE/lib/waves/files"       is used, but can be overriden with the environment variable       WAVES_INPUT_PATH.  Multiple views on a given file may be       established by entering the same file name several times.        Files with ESPS headers, SIGnal headers, and no headers are       handled.  OUTPUTfile:      Base name of files to be created by the "save      segment in file" function.  NO CHECK IS MADE FOR      OVERWRITING EXISTING FILES! A list of all files      generated during a given run of waves+ may be browsed      by right mousing the OUTPUTfile item.   OBJECT name:     The name by which to refer to a display ensemble.  All     data views in an ensemble have their time cursors and     markers synchronized and are treated as a unit during     interaction and in other respects.  If a new object     name is specified, subsequently generated data views     become part of a logically distinct ensemble of signals     and displays.  COMMAND(or @file):     A direct command to the xwaves+ program or to an object     displayed by xwaves+, or the pathname of a text file     (preceded by the "@" character) containing commands.     This item may be changed at any time (even in the middle      of execution of a command file).  The default search path     ".:$ESPS_BASE/lib/waves/commands" is used for command files,     but can be overriden with the environment variable      WAVES_COMMAND_PATH.  PAUSE     Mousing this item while a command file is running causes the      command file to suspend execution, much as though a "pause"      command had been encountered in the file.  CONTINUE     Mousing this item causes waves+ to resume reading from     a command file after encountering a "pause" in that file (or     after the PAUSE button has been moused).   Attach:     The name of a function to attach to waves+.  If the     function is in ESPS/bin it may be referred to simply by     its basename.  Otherwise, its full pathname must be specified.  Overlay name:     The relative or absolute name of a SIGnal formant-bandwidth      file or any ESPS FEA file.  Each element of each FEA field is      overlayed with a separate track labelled with the field name      and element number.  By default, the overlay takes place on      the most recently read or computed spectrogram display.    HELP     Mousing this item displays this file.   QUIT     Mousing this item causes waves+ to clean up (saving files),      return the license, and exit.  WAVES+ GLOBALS ==============The waves+ global parameters can all be initialized at startup fromthe .wave_pro file in your home directory.  To change them after waves+ starts, enter          set <global name> <global value>in the space after the "COMMAND(or @file):" prompt in the controlpanel, or enter the name of a command file containing a sequence of "set" commands.  Here is a list of the current globals, with brief descriptions.  For details, see the man page.   bg_color       background color for window frames (6 digits; 2       each for red, green, blue) (see also fg_color)  colormap       file name of an RGB color map (see "COLORMAPS"       below)  command_step       Allows the user to single-step through command       files.    ctlwin_x       x coordinate of upper left of control window  ctlwin_y       y coordinate of upper left of control window  debug_level       > 0 causes debug messages to be printed.    def_header       filename of a header for use with headerless       data; the default startup profile       ($ESPS_BASE/lib/waves/.wave_pro) sets this to       $ESPS_BASE/lib/waves/files/def_head.feasd, which       is an ESPS FEA_SD header for single-channel,       SHORT, sampled-data, with sampling rate 8000 Hz.       A default SIGnal header is in       $ESPS_BASE/lib/waves/files/def_head.sig.  The       default search path used for default header file       names is ".:$ESPS_BASE/lib/waves/files"; this       can be overriden by setting the unix environment       variable WAVES_INPUT_PATH before starting       waves+. If the environment variable DEF_HEADER is       defined when waves+ starts up, its value takes        precedence over def_header.  Thus, if you want       def_header to change for different input files while       waves+ is running, then DEF_HEADER should not be defined.  do_color       0 or 1 to enable B&W or color operation; This       global is set automatically on startup prior to       reading the startup profile.   dsp32_wait       Specifies the number of attempts (at one second       intervals) that waves+ will make to use an       installed DSP32 board before giving up.   edit_ganged       1 to edit all signals in object, 0 for just one  fea_sd_special       1 to treat ESPS FEA_SD files as a special case,       0 to treat in standard FEA manner.  If       fea_sd_special == 1, the sampled data from ESPS       FEA_SD files are read in as SHORTs (regardless       of their external representation).   fg_color       foreground color for window frames (6 digits; 2       each for red, green, blue) (see also bg_color)  first_x       x coordinate of upper left of first window created  first_y       y coordinate of upper left of first window created  funcname       an attached function (like "label" or "spectrum")  f0_min       minimum frequency to display for F0 files  f0_plot_specs       plotting method and optional ASCII symbol to use.    f0_range       range in Hz to display for F0 files  f0_size       fraction of canvas for plotting F0 for F0 files  image_clip       This is used by the digital halftone algorithm       when spectrograms are displayed on a monochrome       monitor.  Values between MAX and (MAX -image_clip) 	    are displayed in black.   image_range       Everything below (MAX - image_clip - image_range)        is shown in white for spectrograms on monochrome monitor  inputname       default pathname to appear at "INPUT file" prompt  invert_dither       If set to non-zero, this causes digital-halftone images       to appear with black and white pixels reversed ("inverse video").    line_type       plotting algorithm to use for plotting generic vector signals.    left_op       text corresponding to desired left button operation.  max_buff_size       determines a limit on the number of bytes of       storage that waves+ will attempt to allocate for       in-memory data storage for any one signal.  middle_op       text string corresponding to desired middle button op  min_spec_height       minimum height in pixels of spectrogram windows  min_spec_width       minimum width in pixels of spectrogram windows  nb_spect_params       file with parameters for "narrowband" spectrograms 	    (see also wb_spect_params)  objectname       default name to appear at "OBJECT name" prompt  options       hexidecimal magic number (see "OPTIONS" below)
