Hello Doug, sorry for the delay. But thank you for going through the log and giving me helpful advice. The problems I was having with registration were down to the fact that the anatomical (brain mask) and functional were oriented differently and the flirt command line options (search angle in x

From the output it looks like the func-anat registration is off, probably because of the partial FoV is causing the FSL registration used to init BBR to be off (often happens with a partial FoV). Were the anatomical and functional acquired at the same time? If so, then you'll have to bypass r

The second warning you don't need to worry about. I should change that to not be a warning. reg-feat2anat is only registering the functional and anatomical. If the registration to mni152 does not look good, then that is an FSL issue doug On 01/30/2014 11:06 AM, Mariam Sood wrote: > Hello, > >

Which version of freesurfer are you running? At one point, reg-feat2anat was dependent on the feat registration, but "now" it is not. I don't know whether you fall into the "now" category. If you have a partial FOV, then it will probably fail. You can test this by running bbregister outside of

Dear all, I'm having a slight problem with reg-feat2anat to transform functional data (FSL) to anatomical (Freesurfer) in that the resulting transformation seems completely wrong. What I've done so far is the following: 1) run FEAT including the normal FEAT registration (which I know fails due to

Hello, I'm trying to display some FEAT statistics on a surface I created using Freesurfer using instructions from http://www.fmrib.ox.ac.uk/fsl/freesurfer/index.html. The automatic registration function reg-feat2anat seems to have failed and I'm not sure what I should do to re-orient the slices
