Couple of atlasviewer questions - "finding" reference points and installing atlas
Hello! I have two questions about atlasviewer.
1. When I import subject specific MRI anatomy and am prompted to select reference points (Cz, Iz, Nz, LPA RPA), should I just select these points by "eyeballing" and estimating where these points are on the head? Any tips on how to improve the accuracy of selecting these points?
2. I have a segmented atlas file available in -.nii format that I'd like to import into atlasviewer to identify which specific regions my probe is covering. When I use the dropdown "install atlas" function in the atlasviewer GUI, it states that the folder where my -.nii file is located is not a valid directory. Is there any way to get the -.nii file in the appropriate format so that I can import it into atlasviewer?
Thanks for your help!
I gather you already looked at the lecture here
I just looked at the lecture and it doesn't explicitly state the format needed for importing MRI... strange.
That lecture maybe does provide pointers on choosing the ref points though. Also, a series of papers by Ippeita Dan speaks to this point. Here are some of the paper citations:
There are specific details on how to import MRIs on the wiki here
