Batch Requesting Data from the DMC
Tips, Tricks, and How-to's
The following guidelines will help in submitting a BREQ_FAST
request for data.
Use the correct format http://www.iris.edu/manuals/breq_fast.htm
Include Header Information so we can find you correctly
• .NAME, .INST, .MAIL, .EMAIL, .PHONE, .MEDIA, .LABEL, .END
• The .END line indicates to the parser that what follows is the data
being requested, so without it the request will fail.
No line breaks within a request line
• correct:
GNI IU 2004 03 26 19 30 00.0 2004 03 26 20 45 00.0 1 ???
• incorrect:
GNI IU 2004 03 26 19 30 00.0
2004 03 26 20 45 00.0 1 ???
Remember to ALWAYS left-justify all the lines, particularly the token lines
beginning with “.”
Keep it simple
Be sparing with wildcards
• The more requested, the longer it takes to process
Keep your email simple, plain text, and free of any attachments or special
effects: animations or signatures
Make sure your email server does not add additional characters or attachments
to your request
IRIS automated mail is not SPAM
Enable your email server to recognize incoming IRIS mail(s), otherwise
choose another email address in the .EMAIL token that will enable pass-through
Some institutions impose numeric limits to how many emails can be sent
to distinct users by configuring mail servers to block excessive messages
over fixed time domains. REMEMBER: IRIS will send you TWO automated emails
for each request, the first being an acknowledgement that it was received,
the second indicating that the data is ready for download.
Rejected emails get returned to IRIS and can clog up the IRIS mail queue
causing delays to your request(s) and other’s request(s)
How To Track the Status of Your Requests
There is a cyclic nature to the submission of breq_fast requests for
a variety of reasons. Most of the time, requests are processed within
minutes of being received. However, since the community
of researchers who access data from the DMC is globally distributed,
you may want to be able to see who your are competing with should there
be unexpected slowness. See below for tips on how to check the condition
of the request queue and more importantly, the status of your requests
specifically.
How to Check the Status of a Request http://www.iris.edu/data/
Click on ‘Mail Queue’ to check the status of new requests waiting
to be processed
Click on ‘request status’ to check the status of your request
as it is being processed
Click on ‘recent shipments’ to view recently completed requests
