NAME
artsasagg - utility to aggregate AS matrix objects in time domain

SYNOPSIS
artsasagg [-v] [-i ifIndexList] [-I ifIndexList] [-h hours]
          [-o] [-q] outfile infile(s)

DESCRIPTION
artsasagg is a utility that reads AS matrix objects from ARTS files (infile(s)) and aggregates them in the time domain, placing the resulting AS matrix object(s) into an output file (outfile). For example, you may use artsasagg to aggregate 5-minute AS matrix data to 1-hour AS matrix data.

OPTIONS

-v  The -v option causes artsasagg to print version information and exit immediately.

-i ifIndexList
    The -i ifIndexList option may be used to select only data which contains an interface index attribute in ifIndexList. In other words, the -i ifIndexList option lets you select data from particular interfaces or sets of interfaces. ifIndexList may contain hyphens (indicating an inclusive range) and commas. For example, -i 1,2,5-8 would select data with an interface index attribute of 1, 2, 5, 6, 7 or 8.

-I ifIndexList
    The -I ifIndexList option may be used to combine data which contains an interface index attribute in ifIndexList. In other words, the -I ifIndexList option lets you aggregate data across a set of interfaces. ifIndexList may contain hyphens (indicating an inclusive range) and commas. For example, -I 1,2,5-8 would aggregate all data data with an interface index attribute of 1, 2, 5, 6, 7 or 8. The resulting aggregate objects will contain an interface index attribute of 0.

-h hours
    The -h hours option may be used to specify the period of aggregation, in hours. The hours argument accepts a decimal value to permit aggregation by fractional hour values. When the -h hours option is not used, artsasagg will write a single AS matrix object for the entire time interval seen in infile(s) to outfile.

-o  By default, artsasagg appends to the output file, so you may accumlate aggregate AS matrix objects in a single file over multiple invocations of artsasagg. You may override this behavior with the -o option. This will cause artsasagg to overwrite the output file instead of appending to it.

-q  By default, artsasagg prints a '.' for each AS matrix object it reads and prints a '+' for each object it writes. You may suppress this behavior using the -q (quiet) option.

EXAMPLES

artsasagg -h 1.0 /tmp/asagg1hr.19980821 arts.19980821
