Scream!'s source tree has two main parts: Files, which contains all the
files you have replayed (including automatic replay: see
), and Network, which represents your seismic network.
Beneath Network is a list of all the network servers Scream! is
connected to, plus the entry Local for your computer's own serial
ports.
The next layer contains the serial ports themselves. These icons are
provided to help you identify the instruments, as well as providing
direct terminal access.
You can tell Scream! to ignore a particular instrument by right-clicking
on its icon and selecting Ignore. When you do this, Scream! will
discard any blocks it receives from the instrument. They will not
appear in the stream buffer or be recorded to disk. Select Ignore again
to stop ignoring the instrument.

Icons
Instrument icons change colour to provide you with a quick overview
of the instrument's timing and mass position status:
If both halves of the instrument icon are clear , Scream! has not
received any information from the instrument since the program
started.
If the top half is green , the instrument has reported a satisfactory
timing fix.
If the top half is yellow , the instrument has reported a gap in the
timing stream. This will occur if the GPS signal deteriorates to the
point where the receiver cannot keep a lock on the satellites.
