Ok - thank you! I will speak to the person who generated the files then.

I don't know how you (or someone else) generated the nifti files in the first place, so I can't help there. If you did not generate them, then talk to the person who did. I do not really recommend trying to do it by hand. You can get AP and SI correctly, but you'll never know whether they are LR reversed or not

Ah, I see - how would I be able to do either of those? And would I have to check the geometry of each scan individually? Not sure how that works, but I have a substantially large dataset.
Thank you for your response!

That means that geometry information (ie, what is left and right, anterior or posterior) is not part of the nifti file. Without that information, the anatomical analysis cannot be done. You will either have to fix it yourself (ie, imbed that info into the file) or, better, recreate the file with the proper geometry info On 09/11/2017 01:52 PM, Ariana Vajdi wrote: > Hello, > > Hope this message finds you well. > > I was beginning to run recon-all on a dataset and was encounteringa
