Unformatted text preview: function ctf_write_mri(mri, fileName, force) % ctf_write_mri - write a CTF .mri file % % ctf_write_mri(mri,fileName,force) % % mri is a data struct returned from ctf_read_mri. It may contain % mri.file, in which case, you do not need the fileName input here. If the % file exists, you are prompted for a new file name, unless force = 1. % % The CTF MRI File format used by MRIViewer consists of a binary file with % a 1,028 byte header. The MRI data can be in 8-bit (unsigned character) or % 16-bit (unsigned short integer) format and consists of 256 x 256 pixel % slices, stored as 256 contiguous sagittal slices from left to right (or % right to left if head orientation is left-on-right). Each slice is stored % as individual pixels starting at the left, anterior, superior % corner and scanning downwards row by row. Therefore the coronal % position is fastest changing, axial position second fastest % changing and sagittal position slowest changing value in the % file, always in the positive direction for each axis (see section % on Head Coordinate System for axis definitions). By default CTF % MRI files have the file extension .mri % % <>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> % % < > % % < DISCLAIMER: > % % < > % % < THIS PROGRAM IS INTENDED FOR RESEARCH PURPOSES ONLY. > % % < THIS PROGRAM IS IN NO WAY INTENDED FOR CLINICAL OR > % % < OFFICIAL USE. > % % < > % % <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<> % % % $Revision: 1.1 $ $Date: 2009/01/30 03:49:27 $ % Copyright (C) 2003 Darren L.
