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

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
