NAME

stripVme - strip hdrs or data from datataking recs (ao)

SYNOPSIS

stripVme [ -dhq ] [ -f firstScanNumber ] [ -l lastScanNumber ] [ -g firstGroup lastGroup ] [ -o ordinalScanToStart ] [ -n numberOfScans ]

DESCRIPTION

Standard Arecibo datataking records contain a header followed by data. stripVme will select a subset of scans and records within a file and strip off the headers, data, or neither. The input is taken from standard input and the output is written to stdout.

A selection criteria allows creating a subset of the file. For a record to be output it must satisfy all of these criteria. With options -f and -l you can specify the first and last scan numbers to include. Option -o choses the ordinal scan to start with (counting from 1) while option -n sets the maximum number of scans to output. Option -g will pick a subset of records within each matched scan.

OPTIONS

-d: Strip off the data passing only the headers.
-h: Strip off the headers passing only the data.
-q: Run quietly not outputing the current record number to stderr.
-f firstScanNumber: The first scan number to start processing.
-l lastScanNumber: The last scan number to process.
-g firstGroup lastGroup: The first, last record within each scan to output.
-o ordinalScan: The ordinal scan within the file to start with (count from 1).
-n numberOfScans: The number of scans to process.

EXAMPLES

Strip off the data passing the headers, then convert the headers to ascii.

: stripVme -d < inputfile|printhdrV|more

Output the data from records 5 through 10 of scans 919300005 through 919300012.

: stripVme -h -f 919300005 -l 919300012 < inputfile > outputfile

Output the data from the third through seventh scans.

: stripVme -h -o 3 -n 5 < inputfile > outputfile

DIAGNOSTICS

stripVme checks each header for the header keyword to make sure it has not lost its place in the file.

BUGS

stripVme can read from disc or a pipe. To input from tape you should pipe dd into stripVme.
