Copy .qp file, usually through a filter, to make a new qp file. This example shows selection of two time intervals (or exclusion of all data not in these two intervals).
cl> xray
xr> ximages
xi> qpcopy
input qpoe file name: xdata$rp110590.qp[time=(1606720:1607484, 1611613:1612817)]}
region description: ``'' # This is the ``null string'' which will cause
# entire image to be copied.
output filename: comal
event definition: medium # possibilities are: peewee, small, medium, large, region.
If the command line is too long, there may be problems. If many intervals are specified, the filter should be put in a file and the task directed to the file. e.g. Make a file intervals which contains the line:
time = (a:b,c:d,e:f,...).
Then type input file name
xdata$rp110590.qp[@intervals]
If the input file is time ordered (e.g., *_sti.qp), there is a parameter which must be reset.
qpcopy.qp_mkindex = no
qpcopy will now operate on the time-ordered input file.
