parseFN2STA

get station from file name

Description

station and component are assumed to be the last elements of a file name - this function returns a list with these text strings.

Usage

parseFN2STA(fn, ista, icomp, sep="\\.", dir=0  )

Arguments

`fn`	text file name
`ista`	index of station name counting from the end of the file name
`icomp`	index of station name counting from the end of the file name
`sep`	separator token in file name
`dir`	integer, default=0, direction for counting. see details

Details

Some seismic data formats store the station in the file name rather than the seismic header. The default (dir=0) assumes that the station name and the component name are the last items on the file name seperated by a period. So ista and icomp are computed from the end of the file name, i.e. ista=1 and icomp=0. If (dir=1) the counting is from the beginning of the string and the count starts at 1. Remember to count double tokens, they return a blank.

Value

list(sta='text station name', comp='compname')
