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.

Examples

parseFN2STA('/data/wadati/bourbon/GUATEMALA/SEGY/R009.01/07.009.22.25.34.CAS.E')

fn  <- "2011-11-06-0637-21S.SI01__003_SI01__SH_N_SAC"

parseFN2STA(fn, 4, 1, sep="_"  )
### or:
parseFN2STA(fn, 4, 7, sep="_", dir=1  )
