Structural Scans

Dear All, Thanks to some work from Andre, it has now been determined that the current structurals are fit for purpose. Although the scalp identification is a little noisy, the fits to the scalp information derived in MEG do not appear to be unduly compromised. So, structural scans can be acquired for the use with MEG data. Although Andre has checked the registration of the MRI and MEG scalp information on a few data sets, it really would be helpful if all users who acquire such data could visually inspect their registrations (the docwiki has information on how this can be done). Please alert us to any discrepant registrations and proceed with caution. Sorry for the rapid turn around on this issue. I am loath to recommend scanning when the images are clearly not of the quality that we have previously obtained, but in this case I think we can proceed (with caution). The change in the image quality will still be pursued with GE. Happy scanning! Tony
