MINC 2.0 Global Attributes

These two attributes, each consisting of text string, apply to the entire MINC file. They are therefore attached to the ``minc-2.0'' group.

1. history - A global string attribute which is used to implement an audit trail. This is a character array with a line for each invocation of a program that has modified the dataset. All MINC applications should append a line containing: date, time of day, user name, program name and command arguments for each processing step. This attribute should be considered mandatory.

2. title - A global string attribute which provides a description of the MINC file's contents. In practice this is optional and somewhat rarely used.
