-i{ijk}s will change the voxel size of the columns, rows, and slices, respectively

-i{ijk}d will change the direction cosines of the cols, rows, slices

Dear Freesurfer experts,

Could someone please let me know what is the meaning of the arguments -iid, -ijd, -ikd, -iis, -ijs, and -iks of mri_covert?

From the internet and by typing mri_convert on the command line I only managed to find the following information:

-iis, --in_i_size <size>

-ijs, --in_j_size <size>

-iks, --in_k_size <size>

-iid, --in_i_direction <R direction> <A direction> <S direction>

-ijd, --in_j_direction <R direction> <A direction> <S direction>

-ikd, --in_k_direction <R direction> <A direction> <S direction>

However, I don't still understand what is the effect of those argumnents in the following command:

mri_convert gre_000.bfloat data.mgh -iid 1 0 0 -ijd 0 -1 0 -ikd 0 0 1 -iis 5 -ijs 5 -iks 5

Are the arguments describing the direction and voxelsize of .bfloat?

Best,

Maria
