hi
the niftilib do it well i mean seperate .nii into .img and .hdr files as suggested by bob.but i am readiing MRI-T1 images only, my program reads the .nii file and giving me all the information about the header file and on the basis of this i am deciding that i do not missing any information about the .nii file.
i am putting below the result of my program just for information that i want to confirm that am i right or not?

thankx for such a quick response.
