The MRtrix configuration file | |
|---|
MRtrix applications will attempt to read configuration information from a number of possible locations, if they exist. There will in general be a system-wide configuration file, and a user specific configuration file. Their exact location is platform-dependent, as detailed below:
| platform | location |
|---|---|
| Unix | system: /etc/mrtrix.conf user: $HOME/.mrtrix.conf |
| Windows | system: C:\mrtrix.conf user: $HOME\mrtrix.conf (e.g. C:\Documents and Settings\username\mrtrix.conf) |
The system-wide configuration file will be read first (if found), followed by the user configuration file (if found). In case of conflict between the system-wide and user configuration, the user settings will be used. If a particular configuration parameter is not defined, MRtrix will use hard-coded defaults.
The configuration files are text files, with each line containing a key: value pair. For example:
Analyse.LeftToRight: false NumberOfThreads: 2
Note: key names are case-sensitive.
The value entry may be interpreted by MRtrix applications as either:
These parameters are currently interpreted by MRtrix:
| Analyse.LeftToRight | bool | specifies the order in which voxels are stored in Analyse format image data files. |
| NumberOfThreads | integer | number of threads to lauch in multi-threaded applications (e.g. csdeconv) |
