Dear Lino, Please upload your input images (example_func, structural + any fieldmaps) to the following: https://oxfile.ox.ac.uk/oxfile/work/extBox?id=68312615463381F4C Also, can you let me know how you were running it (e.g. through the FEAT GUI) and what parameters you are using. 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: Wednesday, 11 May 2016 16:47 To: "[log in to unmask]<mailto:[log in to unmask]>" <[log in to unmask]<mailto:[log in to unmask]>> Subject: Re: [FSL] BBR misregistration Hi Mark: Yes, the structural image displays a good WM segmentation and the EPI image has reasonable GM/WM contrast. The initial registration (I used flirt) also looks good. How do I upload the images? Thanks for your help Lino
