MINC general attributes

These attributes apply to any variable in the file.

MIvartype

A string identifying the type of variable. Should be one of MI_GROUP, MI_DIMENSION, MI_DIM_WIDTH or MI_VARATT.

MIvarid

A string that identifies the origin of the variable. All standard MINC variables should have this attribute with value MI_STDVAR. Variables created by users should have a distinctive name that will not be the same as the names used by other applications.

MIsigntype

The NetCDF format does not need to know the sign of variables since it does not interpret values -- it is left up to the invoking program to worry about the signs of integers. Because the MINC interface translates variables, it must have this information. MIsigntype is a string with value MI_SIGNED or MI_UNSIGNED. The default values are MI_UNSIGNED for bytes and MI_SIGNED for all other types.

MIparent

A string identifying by name the parent variable of this variable (either in the data hierarchy or as the parent of this variable attribute).

MIchildren

A newline-separated list of the children of this variable (in the data hierarchy).

MIcomments

Any text that should be included with this variable.

MIversion

A string identifying the file version. The current version is MI_CURRENT_VERSION. Each version can be identified by a constant of the form MI_VERSION_1_0.

The constants MI_TRUE and MI_FALSE are provided for boolean attributes.
