Actually you decode the base64 to binary data, then decompress compressedLen bytes of that data to get the binary peaks info you're already used to dealing with. For an example have a look at * http://sashimi.sourceforge.net/trunk/jrap/sax2/src/org/systemsbiology/jrap/SAX2ScanHandler.java *
Not perl, I know, but gets the idea across.
