Restricted Data Access

Restricted Data Access

Some data at the DMC is restricted. For more information about when/why data is restricted go to this IRIS page.

 

To request data for a restricted experiment, you must first contact the PI of the experiment for a 5-character password.

 

1) You need to have OpenSSl installed on your computer.

On Macs and Linux it is pre-installed under /usr/bin/openssl

On WIndows you can get it at this link http://www.slproweb.com/products/Win32OpenSSL.html

2) Register to request data for the experiment through IRIS
http://www.iris.edu/data/restricted_req.htm

3) You will recieve an email from IRIS with two passwords, one for authorized access and one for openssl.

4) After you have received that email, you can submit a breq_fast request for the data
IMPORTANT! USE THE EMAIL ADDRESS IN THE .EMAIL FIELD THAT WAS SENT TO YOU IN THE AUTHORIZATION EMAIL

5) You will receive an email that IRIS has received your request for data.

6) You will recieve an email from IRIS when you data is available

7) Follow the link in your email to download the data on the ftp site (the file name should be a .openssl file)

8) Decrypt the data by running a OpenSSL command on your computer
Use the 'openssl password' from the email
The command has the following structure:
/path/openssl enc -d -des-cbc -salt -in {seed.openssl} -out {seed} -pass pass:{passwd key}
where
/path/ is the path to your openssl program
{seed.openssl} is the name of your downloaded file
{seed} is the name you would like you .seed file to be called
{passwd key} is the openssl password key given to you in the email

This converts the .openssl file to a .seed file

6) Read the file using rdseed and converted to your preferred format (SAC, ASCII, etc.)
