[Mristudio-users] How to stop scanner averaging of DTI data?

[Susumu Mori]

In Siemens, if you do NSA = 2, they actually save two separate files
without in-scanner averaging.
If we do the same thing for Philips, I believe they save only one file
after averaging.
Both are fine, but the former way allows us to co-register the two separate
scans. This theoretically is more robust against motion.
I am not sure if 2 NSA are scanned next each other and if so, you may not
have to worry too much about it.
I wonder if somebody knows if that is the case.....
