# environment¶

Settings from the system environment relevant to NIPY

 Return the closest possible equivalent to a ‘home’ directory. Get systemwide NIPY configuration file directory Get the NIPY user directory

## get_home_dir¶

nibabel.environment.get_home_dir()

Return the closest possible equivalent to a ‘home’ directory.

The path may not exist; code using this routine should not expect the directory to exist.

Parameters
None
Returns
home_dirstring

best guess at location of home directory

## get_nipy_system_dir¶

nibabel.environment.get_nipy_system_dir()

Get systemwide NIPY configuration file directory

On posix systems this will be /etc/nipy. On Windows, the directory is less useful, but by default it will be C:\etc\nipy

The path may well not exist; code using this routine should not expect the directory to exist.

Parameters
None
Returns
nipy_dirstring

path to systemwide NIPY configuration directory

Examples

>>> pth = get_nipy_system_dir()


## get_nipy_user_dir¶

nibabel.environment.get_nipy_user_dir()

Get the NIPY user directory

This uses the logic in get_home_dir to find the home directory and the adds either .nipy or _nipy to the end of the path.

We check first in environment variable NIPY_USER_DIR, otherwise returning the default of <homedir>/.nipy (Unix) or <homedir>/_nipy (Windows)

The path may well not exist; code using this routine should not expect the directory to exist.

Parameters
None
Returns
nipy_dirstring

path to user’s NIPY configuration directory

Examples

>>> pth = get_nipy_user_dir()
