Generate a Summary File Using JWEED

Q: I am enquiring after I received the SEED file that I requested, how can I add the .summary file when using rdseed to extract the data. I want to add the
summary file because I want the output .SAC file with event information. I have read the tutorial on your website, but there is no mention of this problem.

A:
How to generate a summary file using JWEED.

Users can create summary files interactively by using the JWEED program. 
In JWEED, the user queries for events, then queries for stations, and finally creates a summary file by selecting the phases to time window from.

This process is covered in the JWEED Tutorial video at

JWEED Manual

Generate Summary File: When you click on this button JWEED will calculate the start/stop times and construct a summary file. Each event processed is appended onto the list.
 
A summary file is a text file used by JWEED as an intermediary format. JWEED will use the summary file to convert to BREQ_FAST /Net DC type request formats or the DHI server supported formats.
 
Being a text file, a summary file is easily viewable. Looking inside you will see each event listed. Underneath each event are the stations for which JWEED was able to calculate arrivals. Underneath this is a listing detailing the phase arrival time calculations.
