THE SIMIND.INI FILE
Stored in the special directory (smc_dir) is a file called simind.ini
which is an ASCII file containing default values for some of the
variables. This file allow the uses to set up values differently for
different systems. The ini file can also be defined for special
projects. An application is here a simulation were different values of
the density for the Zubal phantom needs to be defined. Then, the used
can give a special ini file name at the command line level. For example,
if the special file is called proj1.ini then the command looks like
c:\> simind intput output proj1.ini/tr:11
It is important that the file name is gives as the third name and the extension *.ini is included
!.
The simind.ini can also be defined in some different ways. If the environmental variable SMC_INI is set
to the proper path and name of the ini file then this will be used. Alternatively if a ini file
is copied to simind.loc and stored in the SMC_DIR then this will be used instead of the simind.ini
