Details 





VMR 
yes 
 reoriented to sagittal  rescaling to 1mm3 (to isovoxel)  zero fill to 256 x 256 x 256 
yes 
 orientation w.r.t. scanner preserved in qform matrix  sform: if in Talairach space, sform code = NIFTI_XFORM_UNKNOWN sform fields: empty else, sform_code = NIFTI_XFORM_ALIGNED_ANAT sform fields: (composed) transformation matrix 
FMR 
yes 
yes 
 orientation w.r.t. scanner preserved in qform matrix  
AMR 
yes 
 resized to 256 x 256 pixels  rescale intensities between 0255 
yes 

MAP 
yes 

yes 
 cal_max and cal_min set, dependent from map type 
VMP 
yes 
 resized to 256 x 256 x 256 voxels  resolution 1mm3 (same as VMR)  if map type unknown, set to ttest  currently only the first map  rescale values, range dependent from map type 
yes 
 data are reoriented to default in NIfTIcoordinate system  cal_max and cal_min set, dependent from map type 
VTC 
yes 
 rescaling to 3mm3 (to isovoxel) 
yes 
 data are reoriented to default in NIfTIcoordinate system  to data type float (32 bit) 
GLM 
no 

yes 
 choice of statistical map type that can be exported possible types: beta weights, x*y, mean corrected sum of squares, multiple regression coefficient, mean time course, autocorrelation of order 1 (when present). Currently, all map types are set in the NIfTI1 header to 'correlation'. In the next version, this will be improved. 
SRF 
no 
possible with NIfTI 2.0 
under consideration 
 export of vertex coordinates and triangles to separate files  dim[0] set to '5' 
MTC 
no 
possible with NIfTI 2.0 
under consideration 

SMP 
no 
possible with NIfTI 2.0 
under consideration 
dim[0] set to '5' dim[5] indicates number of statistical maps supported SMP versions: 13
