Both the fmri data registered to orig is mismatched, and also the original raw fmri data are mismatched with orig, see the link here showing our raw data (fmri, orig and 152MNI) shown in fslview http://vedlegg.uib.no/?id=297a1242fa82b4b7565b470806254c5a It is orig.nii converted from orig.mgz

And the functional is test.nii.gz? If so, can you upload vol0001.nii.gz, register-test.dat, test.nii.gz, and orig.mgz to our file drop? doug On 04/25/2012 07:49 AM, Erlend Hodneland wrote: Both the fmri data registered to orig is mismatched, and also the original raw fmri data are

What images are mismatched? Specifically, which anatomical image are you loading into fslview? If you have not loaded the orig.mgz (converted to nii), then there will be be a mismatch. doug On 04/24/2012 04:29 AM, Erlend Hodneland wrote: Hi again, We are trying to do the same as was done

Hi Erlend, while the images in the tkregister2 pics are oriented correctly the registration is way off. What images are you loading into fslview? You'll need to convert the orig.mgz into nii and load that to check the registration. doug On 04/22/2012 04:16 AM, Erlend Hodneland wrote: Hi

Hi again, the registration looks fine in tkregister2, but is apparently wrong in fslview (and also mricron). See the attached files (as link from http://vedlegg.uib.no/?id=399ad2cce1a3138f8eb4f6a06f4acfc4) showing screenshots of fslview and tkregister2. How can this be explained, and how can we

Hi, we are trying to register fmri FEAT data (example_func.nii) to the anatomical scan (processed in Freesurfer) using bbregister to opt. the affine registration before running FNIRT. However, the orientation of the registered image is flipped around and is incorrect after applying bbregister.

what do you mean that it is in the wrong orientation? It should be in the same orientation as the anatomical. How does the reg look in tkregister2? Note that fslview can display volumes in odd orientations even when the orientation is correct. doug On 04/13/2012 03:31 AM, Erlend Hodneland
