To remove the instrument response completely you need "to none" at the end of the
"transfer" command. You might need to use "freqlimits" in your "transfer" command
to limit the low-frequency part of the signal; and I have always found it necessary
to run "rmean", "rtrend" and "taper" on a seismogram before attempting to remove
the instrument response.

I have a pole zero files to avoid instrument response from signal and I use the command like transfer from polezero subtype pz_file . Is this the true way to obtain signal which doesnt include instrument response.
Or I must add to vel end of the command line ?
