read traces from q-file
command: READ <qfile> <rec-list> [<lo-bound> <hi-bound>]
Reads traces from a q-file. The traces read are added to the display list.
parameters
- <qfile> parameter type: filename (without extension)
Name of the q-file to be read.
- <rec-list> parameter type: list of integer (or string "ALL")
Position numbers of traces to be read.
- <lo-bound>, <hi-bound> parameter type: real
Time window read from file. If not specified the whole traces are read. The time window refers to the start time of each trace unless the "/POS"-qualifer is used (see below).
qualifiers
- /swap
Swaps bytes of binary file after reading.
- /zero
Sets zoom value of new traces to zero. Useful for quick redraw.
- /pos=<time-info>
Changes the reference time of the time window specified by parameters <lo-bound> and <hi-bound> from the start time of each trace to the value specified time info entry <time-info>. In this case <time-info> must be of time-type. If <time-info> is of real type it is assumed to be a distance value which is used in combination with the value of a "/vel=<velocity>" qualifier to compute a reduced velocity time window.
examples
- read MYQFILE 1-3,5,6
- reads traces 1,2,3,5,6 from q-file "MYQFILE"
- read MYQFILE ALL
- reads all traces from file "MYQFILE"
- read MYQFILE ALL 20 100
- reads all traces from file "MYQFILE" cutting the traces at 20 and 100 sec
- read/pos=P-ONSET MYQFILE ALL -20 100
- reads all traces from file "MYQFILE" and cuts each trace 20 sec before P-ONSET and 100 sec after it.
