Some of the extended options available in PSS can result in large amounts of cpu use, and are best run in batch. This is hardly ideal for the investigation of the image, as different values for control parameters may be required to be run (eg. search thresholds).
PSS provides the RESTART parameter for this eventuality. Provided
the user has a valid significance map, PSS can be restarted with this map
and the program execution continues from the point where the range of the
significance map is written to the terminal. RESTART is a hidden
parameter, so must either be specified on the command line or prompted for
after using PROMPT. The following example illustrates the method
using the demonstration file,
> PSS MY_PSS_DEMO 1.01 MY_SRC ~ ; Create map on first search
MAP=SIG_MAP \
> PSS MY_PSS_DEMO 1.01 MY_SRC2 ~ ; Try with lower threshold
EXPERT RESTART MAP=SIG_MAP
SIGMIN=3.5
