First, what is you evidence that "ig=-1" is not using a different seed for
each run? (The seed chosen is printed in the output file). This sounds like
a bug, but we need to know the version of Amber, the compiler (+version) and
OS you are using.
Second, note that you generally cannot use "ig=-1" for TI, since the
integration scheme (which depends on ig for ntt=3) needs to be the same
for each of the two groups. So, for TI, you have to manually choose a
different seed for each run, and make it the same in the two mdin files.
