:orphan: .. _ahelp_from3d: ****** from3d ****** .. contents:: :local: | .. code-block:: none Usage: from3d [options] -input fname -prefix rname Purpose: Extract 2D image files from a 3D AFNI dataset. Options: -v Print out verbose information during the run. -nsize Adjust size of 2D data file to be NxN, by padding with zeros, where N is a power of 2. -raw Write images in 'raw' format (just the data bytes) N.B.: there will be no header information saying what the image dimensions are - you'll have to get that information from the x and y axis information output by 3dinfo. -float Write images as floats, no matter what they are in the dataset itself. -zfirst num Set 'num' = number of first z slice to be extracted. (default = 1) -zlast num Set 'num' = number of last z slice to be extracted. (default = largest) -tfirst num Set 'num' = number of first time slice to be extracted. (default = 1) -tlast num Set 'num' = number of last time slice to be extracted. (default = largest) -input fname Read 3D dataset from file 'fname'. 'fname' may include a sub-brick selector list. -prefix rname Write 2D images using prefix 'rname'. (-input and -prefix are non-optional options: they) (must be present or the program will not execute. ) N.B.: * Image data is extracted directly from the dataset bricks. If a brick has a floating point scaling factor, it will NOT be applied. * Images are extracted parallel to the xy-plane of the dataset orientation (which can be determined by program 3dinfo). This is the order in which the images were input to the dataset originally, via to3d. * If either of these conditions is unacceptable, you can also
