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

[Jonathan HARLAP]

alternately (without the ambiguity of $MERGE) something on the order of...

if X is an attribute in a minc header...
minc_modify_header -sinsert "X=`mincinfo -quiet -attvar X original.mnc`" realigned.mnc

would be an inefficient but simple way to do it...

cheers,
