[MINC-users] time and time-width dimension in dynamic image

[Sylvain MILOT]

Yes this is fine for attributes but how do you do this for variables ?

time and time-width are extracted with :

mincinfo -varvalue time dynamic.mnc
mincinfo -varvalue time-width dynamic.mnc

How do you do this with minc_modify_header ?
