Slides
Slides program allows you to prepare selected tomographic cross-sections or layers for publication. It uses configuration files to perform these tasks. Therefore, there are no interactive functions besides those allowed by Matlab figure editor itself. Those Matlab figure editor functions are very useful especially for UNIX users where limited number of image editors is available.
1.
Getting started
First of all you must prepare your configuration files. There are two types of files based on the output configuration file of the Explore program: cross-section configuration file and slice configuration file.
Cross-section configuration
file example:
Seismicity z:\GeoVis\DEMO\seismicity.hyp 2.0 200. Seismicity keyword defines the seismicity plotting feature.
Data z:\DEMO\AMP-global-model.dat z:\DEMO\palT2.cpt Data keyword points to the model and color palette files.
Cut Cut keyword characterizes the cross-section features.
138.00 60.5 160.0 51.40 A' A Cross-section coordinates with corresponding characters.
1 9 1 Lines to be plotted for reference (numbers are layers).
2 Number of tags to be plotted.
139 59 O Tag coordinates (Lon and Lat) with corresponding characters.
140 58 I
Cut
137.0 56.3 159. 50.5 B'

End
End Data End data keyword
EndInput End file keyword
Keyword parameters:
Seismicity keyword can be omitted in the file. In this case no seismicity will be plotted on cross-sections. It is the less time-consuming way to plot the figures.
Once you decide to plot the seismicity following format must be used:
Seismicity [source_file] radius_of_balls width_of_cross-section_km
Source file name can be omitted, in this case seismicity will be taken from the database. However, radius of the plotted balls representing seismicity and width of the cross-section (km) must be specified.
Data keyword specifies the path and file name of the tomographic model and color palette. There are no any options at the moment so far.
Cut keyword specifies the beginning of the cross-section information and the way how to plot it. For example:
Cut Simple cut through the model
Cut 10 + Avg Shows average positive values within 10 km band along the cross-section
Cut 10 – Min Plots only minima negative values within 10 km band along the cross-section
Cut 10 All Max Plots maximum value selected from the 10 km band along the cross-section
Combination of all these parameters is allowed while it follows the same format.
Slice configuration file
example:
Data z:\DEMO\AMP-global-model.dat z:\DEMO\palT2.cpt Paths to the model and color palette files
Mercator 10. 5. Left Bottom 135. 49. 175. 65. Map projection, space between boundary ticks, axis to plot, limits of area.

Name of the map projection must follow the line describing the source data. Following map projections are available:
Stereographic
Orthographic
Azimuthal Equal-area
Azimuthal Equidistant
Gnomonic

Albers Equal-Area Conic
Lambert Conformal Conic
Mercator
Miller Cylindrical
Equidistant Cylindrical
Oblique Mercator
Transverse Mercator
Sinusoidal
Gall-Peters
Hammer-Aitoff
Mollweide
UTM
For example the command line
Azimuthal Equi 2 3 Bottom Left 135. 49. 175. 65.
will plot all layers using Azumuthal Equidistant projection showing bottom and left axis with space between ticks 2 degrees in longitude and 3 degrees in latitude direction. Only area defined by 135. 49. 175. 65. (LonMin LatMin LonMax LatMax ) will be visualized.

Running the Slides program
Type Slides in the command window of Matlab. Two windows will appear: the Main window and Control window.
Main window:
Control window:
Main window visualizes the figures while Control window allows users to control general representation.
Press right mouse button near the border of the Main window to call pop-up menu. Following options will be available:
Load Cuts Option to load cross-section configuration files
Load Slides Option
to load slice configuration files
Load Volcanoes Additional
option to load custom file with volcanoes location
Format Calls Command window.
Next Page Shows
next page of the figures not displayed in the current Main window
Prev Page Shows
previous page of the figures not displayed in the current Main window
Legend Allows
to select desired color-palette at the bottom of Main window if
multiple palette files were used.
Save Image Saves
image of the
Main window.
Print Prints

window
Quit
After loading cross-section or/and slices configuration files you should specify number of pictures in X and Y directions using corresponding slide-bars of the Control window. Press Row-wise button to specify the order in which they will be distributed in the Main window. Finally, press Set Format button to activate the settings.
You can plot volcanoes pressing Plot Volcanoes button.
Seismicity will be visualized only after pressing Plot Seismicity button. Remember – this option is activated only if corresponding information is provided in the cross-section configuration files.

you must press Plot Seismicity
button to visualize the seismicity on cross-section. Program Slides allows you
to visualize both types of files. You can load SLC and CUT files one by one
without exiting from the program. For example, if you download previously
discussed SLC and CUT files of the
Do not forget to specify 2 figures along Y or X directions on corresponding slide-bar and press Set format button to visualize both images together.
3.
Figure editing
All information and objects located on the Main window can be moved or edited. Additional comments,
lines etc. can be added as well. You must use standard Matlab
editing tool-bar 
located at the top of the Main window to perform these tasks. Please, use Matlab
manual for further information.
TIP: Use cut/past option to change the layer of objects or check out Hide box in axes properties.
