Hi, I also get this bad result and I'm not sure why. I'll keep looking into it, but I wanted you to know the news (good that you'd done nothing wrong, but bad that there isn't a quick and easy fix that I can see yet). All the best, Mark From: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> on behalf of Lino Becerra <[log in to unmask]<mailto:[log in to unmask]>> Reply-To: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> Date: Thursday, 12 May 2016 12:52 To: "[log in to unmask]<mailto:[log in to unmask]>" <[log in to unmask]<mailto:[log in to unmask]>> Subject: Re: [FSL] BBR misregistration Dear Mark: I'm running it through Melodic_gui and used BBR. I also used epic_reg and produced the same result. I uploaded the images you requested as well as the picture of the registration as it appears on the report_reg web page. I must add that it happens with a few subjects, not all of them. This is not an isolated case. Thanks so much for your help! Lino
