Cut channels from frames in frame files.
lalfr-cut list [file ...]
The lalfr-cut
utility cuts out selected channels (as specified by list
) from each file
and writes frames containing these channels only to the standard output. If no file
argument is specified, or if a file argument is a single dash (-
), lalfr-cut
reads from the standard input. The channels specified by list are comma-delimited channel names.
To cut the channels chan1
and chan2
from file framefile.gwf
and output frames to standard output:
lalfr-cut chan1,chan2 framefile.gwf
