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.
