Dear experts,
When it comes to assessing the quality of fMRI integration in Freesurfer, is a value of > 0.5 considered a good registration? I was led to believe that from the multimodal tutorial website, and after checking the quality of my output I was satisfied with the result for each of my participants. However, I came back to the multimodal tutorial later after two weeks, and noticed that the page had been edited and now it says that any value <0.5 is considered a good registration. How would I go about resolving this issue, seeing as I visually inspected my output after each automatic registration and everything seemed fine? Most of my registration values were about 0.5-0.6.
Please let me know.
Thanks!
Arsenije
There is no way to give a hard-and-fast threshold on the quality. 0.5-0.6 is not considered bad. If the registrations look good to you visually then it is fine
