Memory Allocation Error

[hkburns.18Participant]

Hello. I keep running into an error message, while running the normalization step. Do you know how I can allocate more memory?

Exception caught:

Hi Heather,

You can’t allocate the memory manually. The program will do it during running. The error you got indicates that you haven’t enough memory in your computer. You need at least 16G RAM (or even larger) to run ANTs based normalization.

Best,
Ningfei
