#> Usage: fslswapdim <input> <a> <b> <c> [output]  where a,b,c represent the new x,y,z axes in terms of the  old axes.  They can take values of -x,x,y,-y,z,-z  or RL,LR,AP,PA,SI,IS (in the case of nifti inputs)  e.g.  fslswapdim invol y x -z outvol  or    fslswapdim invol RL PA IS outvol  where the latter will convert to axial slicing   (to match the avg152 images)
