DESCRIPTION

"EC_MO_correction" is a modification of the "spm_coreg" algorithm written by John Ashburner (http://www.fil.ion.ucl.ac.uk/spm) for dealing with EC distortions and motion correction of diffusion weighted images based on a linear eddy current model described in Mohammadi at al. (2010).

NOTE

This toolbox comes with absolutely NO WARRANTY! It is especially not intended for any clinical or diagnostic use.

GETTING STARTED

The toolbox requires Matlab and SPM8 to be installed on your computer. After downloading the toolbox archive, extract the files into your SPM working directory. The archive contains a C-file "spm_hist2_z_exp_polyval2.c" which has to be compiled before using. In order to do this, launch Matlab in your working directory. Start the compilation by entering the command

mex spm_hist2_z_exp_polyval2.c

Now the installation is complete and you can start SPM and use the toolbox by calling the function "EC_MO_correction" in Matlab to estimate the EC distortions and motion parameters. Furthermore, you can write the data by calling the EC_MO_write_rFiles.
