The second level analyses seems to have worked and there are no spaces in my files. Where would I upload my feat directories so you could take a look?

Hi - did the second-level analyses complete ok?
Please check that you have no spaces in your folder or filenames, if
you're still not sure what's going wrong then feel free to upload your
complete second-level FEAT output directories for us to have a look at.
Cheers.
