- The plane of acquisition (axial, coronal, sagittal) may now be specified by the user.
- Min/max values of the data are properly interrogated if cal.min/cal.max or glmin/glmax are not specified.
- Added accessor/replacement functions for cal.min and cal.max NIfTI metadata fields.
- Fixed bug in pixdim<- replacement function, should work now.
- Fixed bug in writeNIfTI so that FSLView can correctly identify the min/max values.
