[MINC-users] Modify frame times in mincheader

[Robert D. Vincent]

Hi Thomas,

Vlad is correct. There is no minc command other than mincedit that allows
you to modify the contents of a dataset - and the acquisition times are
stored in a dataset.

If this is something you need to automate in a script, it would be pretty
easy to extend minc_modify_header to support this case.
