Standalone Version of STP Program recommended for repeated searching of archive
The program can be run standalone on the user's local computer by downloading the software from our product download page. Users who use the standalone version of the software can retrieve the waveforms directly to their local machine.
The newest version of the standalone STP client is 1.6.2. This version corrects a bug that caused a segmentation fault on 64-bit machines when the main STP server was overloaded.
