[MSNoise] [EXTERNAL] Re: Possible to use data from ref2mseed?

The filenames take the serial number of the DAS automatically. I do not
think this behavior can be changed during conversion  The header values
are populated by a parameter file input by the user. Below is a few lines
of the parameter file:

#das;refchan;refstrm;netcode;station;channel;loccode;encoding;samplerate;ga
in
BACB; 1; 1; PA; CE1; HHZ; 00; INT32; 125; x1
BACB; 2; 1; PA; CE1; HHN; 00; INT32; 125; x1
BACB; 3; 1; PA; CE1; HHE; 00; INT32; 125; x1
B9F0; 1; 1; PA; R1A; HHZ; 00; INT32; 125; x1


I can change the 'station' parameter to match the 'das' parameter, or
write a script to batch rename the files to match the 'station'. I think I
would prefer to do the latter, as the DAS serial number has no geographic
significance, unlike the station value. For instance R1A, R1B are on Ring
1 of the array and R2A, R2B are Ring 2, etc. CE1 is the center element of
the array.

Do you want me to send you renamed data?

Best,
Rob
