Preliminary Tests and Downloads


Instructions:

1. Download all four of the files below by clicking on the "Download" links

2. The first two files are gzipped "tar" files.  Decompress these (first by using "gunzip", then "tar", though most systems will probably do this automatically if you double-click).  Email me if you have problems decompressing these -- when you're done you should have two directories, one called "SegyMAT" and one called "SeismicLab", which contain matlab scripts called by class_filter.m.

3. Put the data file ("latest_shot_corrected.segy") in a directory where you want to keep seismic data.

4. Open the file class_filter.m in Matlab.  This is the main script to run.

5. Change Line 5 of class_filter.m, which currently reads... [Data,SegyTraceHeaders,SegyHeader]=ReadSegy('/Users/sholbrook/Documents/Hydrates/Storegga_Cruise/Sioseis_jobs/latest_shot_corrected.segy');

...by substituting the correct path name for the blue text above (i.e., the path name of the directory you chose in step #3 above).
6. Make sure that the path names of the directories "SegyMAT" and "SeismicLab" have been added to Matlab's path (using the "File -> Set Path..." command).
7. Run the script "class_filter.m" in Matlab.  You should see a two plots -- one of seismic data and one of a power spectrum.

Let me know if this works!
