Rockspec Project
Tutorial
Here's one task you can try with Rockspec. These instructions assume that you have installed Java version 1.4 or higher and have been successful in launching Rockspec using the instructions on the Download page.
- Download these two files (click on the links and save them wherever you want).
- Launch Rockspec; if you're online can do this by clicking here.
- Click the button "Load Spectra."
- Open the file called "rock_spectra_microns_sorted.txt." These are the target spectra.
- Select the "Rockspec" format. Click OK.
- In the line labeled "Preprocessing Method," click "New."
- Right click where indicated and select "Insert Filter."
- Select "Interpolate..."; click OK.
- Right click on the filter just created and select "Edit."
- Type "7.5 to 24.5 by 0.01"; click OK.
- Click OK to close the Preproprocessing Method editor.
- Click the button labeled "Preprocess." This will filter all of the spectra in the Raw Spectra column and create a column of Preprocessed Spectra.
- In the line marked "Algorithm" (typo; says "AbstractAlgorithmWrapper" now; this will be fixed), click the button labeled "New."
- Select "Modified PC"; click OK.
- In the window that pops up, click "Load Spectra."
- Open the file called "ASUspeclib_v1.5m_microns_sorted.txt." These are the reference spectra.
- Select the Rockspec format; click OK.
- In the line labeled "Preprocessing Method," select the preprocessing method created in lines 6-11. (It will be the one that's NOT called "no preprocessing").
- Click "Preprocess." Now the target spectra are interpolated to the same domain as the reference spectra. (By the way, to view any spectrum in Rockspec, simply double click on its name.)
- To classify the target spectra, click the "Classify" button. The classification will take some time; as the spectra are classified, the results will appear in the Results column. (Depending on the algorithm, this may take some time.)
- To view any result, double click the result in the Result column you're interested in.
