No problem! I don’t know why it has worked on another dataset with a similar size. Someone else might have more insight. I would definitely try it on a computer with either more RAM or more swap space.
Cheers!

I am confused though, as in the past I have run this command on a different data set (similar size) without a problem. I have sporadic access to a Mac w/ FSL and much more RAM, I can try on there to see if that will work.
