 Frequently Asked Questions (FAQ) for the SCEC [[Broadband Platform]]:
-'''* What it the most recent version of the Broadband Platform?'''
+'''# What it the most recent version of the Broadband Platform?'''
 * The most recent version of the Broadband Platform software is posted on a SCEC [[Broadband Platform]] wiki page. We expect to make new releases of the Broadband Platform every 3-6 months.
-'''* Which version of the Broadband Platform should I use?'''
+'''# Which version of the Broadband Platform should I use?'''
 * Several previous versions of the broadband platform have been released by SCEC. New versions of the platform incorporate software updates, improvements, and bug fixes. For this reason, we recommend all new users should use the most recent version of the platform, as posted on the Broadband Platform wiki page. We recommend users migrate their work to the most recent version of the broadband platform at the first opportunity. Previous versions of the platform are still available primarily to support reproducibility of earlier results.
-'''* How can I simulate earthquakes in California, Japan and Eastern North America?'''
+'''# How can I simulate earthquakes in California, Japan and Eastern North America?'''
 * The newest Broadband Platform distribution supports simulations for several 1D velocity models. These 1D velocity models were defined to represent structure in parts of California including Los Angeles Basin, Mojave Desert, Central California Coast, Eastern North America, including Virginia and Eastern Canada, and Western and Central Japan. Broadband Platform users can select a region, and simulate earthquakes in that region for one or more of the ground motion modeling software installed in the platform.
-'''* What region should I use for an earthquake in California?'''
+'''# What region should I use for an earthquake in California?'''
 * The Broadband Platform currently has 3 simulation regions for California: LA Basin, Mojave, and Northern California. Please take a look at this [http://hypocenter.usc.edu/research/bbp/california_gfs_16_5.pdf map (PDF, 133KB)] for a suggestion of what region to use for simulations in California. Please note that these are only approximate and somewhat subjective, but basically, for ruptures located in the Southern California, users should use the LA Basin region. The Mojave region should be used for faults in most of the inland part of Southern California, and the Northern California region should be used for ruptures located in the remainder of the State.
-'''* How can I simulate earthquakes outside California, Eastern North America, and Japan?'''
+'''# How can I simulate earthquakes outside California, Eastern North America, and Japan?'''
 * If users want to simulate an earthquake outside of California, Eastern North America, or Japan, they must select a velocity profile for their region of interest. In future releases of the broadband platform, it may be possible for the user to define a 1D velocity profile, generate Greens Functions for that profile, and then simulate earthquakes using those Greens Functions. Currently, the only platform does not include software to generate new Greens functions, for most simulation methods (EXSIM is an exception to this rule).  So, to use most methods, users should examine the 1D velocity profiles for each of the supported 1D models currently supported, and select the velocity model most like their region of interest. Then, then can run simulations using existing Greens functions. Given a 1D velocity model, simulations can be run with faults can be embedded within this 1D region, and stations can be distributed around the fault, and the ground motion simulations results can be representative of other regions.
-'''* I try to run the tests of UniTests.py. The result tells me that ImportError: No module named scipy.integrate. I wonder what wrong it is.'''

+*The error you are seeing relates to the python software that you are using.
 The Broadband platform using standard python libraries. It also requires several "optional" python libraries that must be added to most python installations. The error you are getting indicates that you need to install one (or more) additional python libraries. These additional libraries are free, but how you install them will depend on the system on which you are installing the broadband platform.

 '''* How can I simulate earthquakes outside California, Eastern North America, and Japan?'''
 * If users want to simulate an earthquake outside of California, Eastern North America, or Japan, they must select a velocity profile for their region of interest. In future releases of the broadband platform, it may be possible for the user to define a 1D velocity profile, generate Greens Functions for that profile, and then simulate earthquakes using those Greens Functions.
