The
program GUI is composed of a menu bar (Menu), an image
display window (Display), an image
display/editing
toolbar (ToolBar), several
monitors (Monitor),
a group of operation buttons (OpMode), a set
of control panels (OpPanel),
a message bar (Message),
and one system status indicator (SysState). The interface is
designed so that the most frequently used functions (e.g., parameter
definition) can be easily accessed from the control panels, while the
less frequently used functions (e.g., file input/output) can be called
from the
menu entries.
The main display
window (Display) is for micrograph,
template, particle stack and 3D model
display.
Under certain functional modes, this window is also used for chart
plot. For image display, view-panning and zooming are enabled by using
the
computer
mouse: press the left button and drag the cursor to pan, press the
right
button and drag the cursor to zoom.
The modular functions of the
system are grouped into various control panels (OpPanel). An OpPanel can be
activated by one of the OpMode buttons.
Information
generated by the program in a computing session will be displayed in
the
message bar. Normal messages will be shown in yellow text, while error
messages will be displayed in red. No error message should appear if a
dataset is correctly processed. A green-red indicator (SysState)
shows the
FREE / BUSY status of the system. When
the system is in the BUSY state, it is performing complex numerical
computation and will not respond to further user interactions.
