NAME

getwfdata - generate an ASCII dump of waveforms with downsampling  

SYNOPSIS

getwfdata [-h] [-ffreq] [-rstart,end] runfile wfnum ... > output.csv  

DESCRIPTION

Getwfdata dumps out the data of one or more waveforms from a runfile, as comma-separated ASCII values. The runfile argument, which must be specified, gives the name of the run file or analysis parameter file for the run of data to be dumped. One or more wfnum arguments give the waveform numbers for the waveforms to be dumped. The output goes to the standard output, which should be redirected to a file. A file name suffix of .csv is recommended for this output file. Output values are in mV by default, unless another type of units is selected for A/D sample display in the runfile's analysis parameters.  

Options

-h
Specifies that an extra header should be added to the output file, showing the time range and frequency requested or assumed.
-ffreq
Specifies the frequency to which you want the data to be downsampled. By default, it will output all data at the effective sampling rate of the first waveform specified.
-rstart,end
Specifies the start and end time in the runfile, in seconds. The default is the whole run, or whatever analysis range is selected in the analysis parameters. To override any analysis range set in the parameters and ensure the whole run is dumped, you can specify -r0,max or -rall.
--help
Causes the program to output a summary of command usage and options.
 

EXAMPLES

getwfdata -f10 apjedro4damp02 5 6 > apj402-56.csv
Extract waveforms 5 and 6 from a runfile at a sample frequency of 10 Hz.
getwfdata -r0,20s apjedro4damp02 7 > apj402-7.csv
Extract first 20 seconds of waveform 7 at its full rate.
