Dear FSL experts,

I usually use mricron to convert dicom images to 4D nii, but this time my 4D data has 1142 volumes and mricron did not work so used mri_convert or unpacksdcm from freesurfer. They produced the 4D data, but the anterior-posterior is (left to right) in opposite direction of previous 4D data or MNI atlas and the fsl registration is incorrect. what is the safest way to correct that?



I do appreciate your attention.

BR,
Elahe
