The package oro.nifti contains functions for the input/output and visualization of medical imaging data that follow either the ANALYZE, NIfTI or AFNI formats. This package is part of the Rigorous Analytics bundle.
Lightbox display of functional MRI “resting-state” acquisition using image(). The axial plane is used by default.
Lightbox display of functional MRI “resting-state” acquisition using image(, plane=”coronal”).
Llightbox display of functional MRI “resting-state” acquisition using image(, plane=”sagittal”).
Orthographic display of functional MRI “resting-state” acquisition using orthographic().
The latest version of oro.nifti (0.3.1) contains a substantial number of updates:
Visualization of NIfTI and ANALYZE S4 objects
Aspect ratio is now respected in the overloaded image() function for “nifti” and “anlz” class objects.
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.
Better treatment of Qform and Sform information.
