make the scanner software apply the correction to fMRI data during data acquisition but I can, in principle, apply 2D or 3D correction to fMRI data afterwards. This only works, though, after splitting up the MOSAIC data. The software version we are using on the scanner is VE11. Cheers, Kri

Hi, I would like to use gradunwarp for offline gradient nonlinearity correction of some data acquired on our local Siemens scanners. I used dcm2niix to convert the dicom data to nifti format. After applying gradunwarp to a T1 image in nifti format (the one that originally has the _ND

Hi Aaron, I'm not sure if it is possible to export the colormaps directly. In any case, I think that one could recreate the colormaps based on the relevant code sections (take a look at
