Dear experts,

I am interested in using the Arterial Atlas available in NITRC.
However, there is a discrepancy between the dimentions of the file that I downloaded (dim1:181, dim2:217, dim3: 181) and the MNI152_T1_1mm_brain.nii.gz (dim1:182, dim2:218, dim3: 182).
Can you please clarify which is the anatomical reference image for this atlas (with same dimensions) and provide a link to download it? I tried adding voxels to the original grid on my own but I would prefer to have the original reference image, just to make sure that the alignment between anatomy and the atlas is correct.
Thank you in advance for your help and support.
Best Regards,

Laura

Thank you very much for providing the link. I had zero padded the Atlas to the T1 MNI standard dimension before writing in the forum, but I wasn't sure that this granted the desired overlap because some voxels of the brain were not classified. I'll refer to the JHU_MNI_SS standard.
Thanks again for your help.
Best regards,

Laura

Dear Laura,
Thank you for your interest. Our Atlas is based on JHU_MNI_SS (181x217x181). For compatibility with the MNI152 template from FSL (182x218x182), you can either "zero pad" the Atlas to the last dimension or "crop" the last dimension of MNI152-FSL. The JHU_MNI_SS (original and "MNI152-FSL compatible") is downloadable from https://github.com/muschellij2/Eve_Atlas...
