Seisgram2k Instructions

[dave d]

A suggestion for the Raspberry Shake help guide for Seisgram 2k.

Present Instruction:

Example seisgram2k execution:

$ java -cp SeisGram2K70_SCHOOL.jar net.alomax.seisgram2k.SeisGram2K  -seedlink "raspberryshake.local:18000#AM_R5DCF:00SHZ#300"

Replace “R5DCF” with your Raspberry Shake’s station name.

___________________

Add:

For Windows:

Create a batch file containing this text using a text editor (notepad) to start the program and connect to your Shake

SeisGram2K70_SCHOOL.jar net.alomax.seisgram2k.SeisGram2K  -seedlink "raspberryshake.local:18000#AM_R5DCF:00SHZ#300"

Replace “R5DCF” with your Raspberry Shake’s station name.

Save the file to the Seisgram2k directory ; example :  (Seisgram2k.bat)

Opening the batch file will load Seisgram2k and connect to your Shake.

Great suggestion. I have added it. This will be reflected when I push the changes up to the cloud later tonight or tomorrow. 

Yours,

David D, thank you.  The BAT file works fine.  I was at a complete loss on HOW to use seisgram2K.  This bat file helps tremendously.  I have to read the manual and figure out how to use it.  Specifically, how do you look at, grab and analyse an event that happened some time past?

Seisgram2k http://alomax.free.fr/seisgram/beta/ Works best for either monitoring live data streams in realtime using the seedlink tools or for analyzing already saved event files.

Swarm is great for looking at data aver extended periods but does not have much in the way of analysis tools. I would recommend using swarm to look over past data and once you have found an event that you want to look at in more detail you can select that event ( not forgetting to include 5- 10 minutes of pre-event signal ) and saving this as an event file. Swarm lets you do this in a number of different formats, I would recommend using .mseed. Or .sac Note by default swarm always saves files with the same name, if you are keeping records of events you have recorded you should rename these files.

Seisgram2k can then be used for a more detailed analysis by opening these saved event files. Available analysis includes, numerous filtering and spectrogram analysis, theoretical travel time picks using selected earth velocity models, instrument response deconvolutions, interactive distance estimation using hodograms ( sliding a seismograph around on a p and s travel time graph to get the best fit ) and three component particle motion analysis (if you have access to three component data )

Seisgram2k does have an option to look at data from the past in big chunks if they are available on web servers in BUD directory structures, usually as day long miniseed files, at the moment this is only available in the IRIIS data server for professional stations but might be interesting to compare your data with that from a nearby prof station. Instructions for using the BUD options are in the short PDF guide at http://alomax.free.fr/seisgram/beta/

Paul, my version (2.62) of SWARM does not allow saving anything except "config files" in the LAYOUT folder.  Sorry, but I don't follow your instructions for SWARM.  I've read other posts referring to SAC files "saved", I haven't a clue how to do that.

The attached Word document shows how to transfer your archived  shake files to Windows and then open them in Seisgram2k.
