| + | |||
| + | ==== Getting the code ==== | ||
| + | |||
| + | Currently, the W-phase package is hosted as a github repository. To check out the W-phase repository: | ||
| + | <code> | ||
| + | git clone https://github.com/eost/wphase.git wphase_package | ||
| + | </code> | ||
| + | |||
| + | To update your W-phase repository (pull changes) | ||
| + | <code> | ||
| + | cd /to/the/wphase/directory/ | ||
| + | git pull origin master | ||
| + | </code> | ||
| + | |||
| + | For more details on using git for W-phase, [[wphase:repository|you can read this page.]] | ||
| + | |||
| + | ==== Dependencies ==== | ||
| + | |||
| + | The w-phase package have only been tested on Unix and Linux computers. You will need the following: | ||
| + | - csh shell | ||
| + | - gcc and gfortran | ||
| + | - python2.7 (or later) | ||
| + | - You have to install numpy, matplotlib, basemap and netCDF4 to run some python scripts which make figures. | ||
| + | - rdseed | ||
| + | - GMT4 | ||
| + | |||
| + | To install these dependencies on MacOs, [[wphase:macos|you can refer to this page]]. | ||
| + | ==== Building the code ==== | ||
| To install the code, we must first setup a few environment variables. If you use csh or tcsh: | To install the code, we must first setup a few environment variables. If you use csh or tcsh: | ||

| + | ==== Using ETOPO01 Global Relief Model ==== | ||
| + | |||
| + | ETOPO01 is a 1 arc-minute global relief model of the Earth's surface | ||
| + | provided by Amante et al. (2009): | ||
| + | <http://www.ngdc.noaa.gov/mgg/global/global.html> | ||
| + | |||
| + | If Basemap is installed, you can optionally draw ETOPO01 topography and | ||
| + | bathymetry. To do so, the path to the ETOPO01 netCDF file must be | ||
| + | assigned to the environment variable $ETOPOFILE which can be | ||
| + | done in your .tcshrc fil (or .bachrc, .cshrc, etc.). The make_grids.py | ||
| + | script have been tested only for grid-registered netCDF file of the | ||
| + | ETOPO1 bedrock file available at: | ||
| + | <http://www.ngdc.noaa.gov/mgg/global/relief/ETOPO1/data/bedrock/grid_registered/netcdf/ETOPO1_Bed_g_gmt4.grd.gz> | ||
