The downloadable file models.tgz contains some velocity models that are used for creating synthetics. To unpack these for use in making velocity models, do the followin:
Create a directory named GREEN which will contain the Green's functions for the individual velocity models
Note the absolute path of this directory. For example this might be/backup/rbh/PROGRAMS.310t/GREEN
Set the environment parameter GREENDIR in the .bashrc
file if you use the bash shell. [If you use another shell, set up something similar]. The line to be added to .bashrc for the parameter above is
export GREENDIR=/backup/rbh/PROGRAMS.310t/GREEN
Refresh the environment
source ~/.bashrc
Note this will be done automatically when you login again.
Install the models:
cd $GREENDIR
gunzip -c models.tgz | tar xvf -
This will create the subdirectory Models with the model files
