Hi,
I would be very, very careful about flipping left and right in any
analysis.
The safest thing to do is to take a completely separate copy of the
data,
flip the ones you want to, and then do a wholly separate analysis,
making
sure that you effectively quarantine this data so that you never get
flipped
images mixed up in any other processing. Otherwise you will easily end
up with a mess where you are no longer sure what is left or right in
images.
All the best,
Mark
