Hi Srishti, you will need to be much more specific to allow me to help you. mni152_subject is not a file that can be input to recon-all (it should be a dicom or nifti or mgz). If you use the same input to recon-all that you used to view it in spm, then the FS output should align with your map.

What is the "MNI template" that you are using. I mean an exact file used. Did you use this file when you ran recon-all? On 04/12/2018 10:23 AM, srishti goel wrote: > Yeah, I am unsure where to go from here as well. So the results can be > viewed in SPM and on the MNI template space itself, sinc

Yeah, I am unsure where to go from here as well. So the results can be viewed in SPM and on the MNI template space itself, since SPM typically does not have a problem showing multiple images in different sizes. Best, Srishti Social/Clinical Research Specialist Child Imaging Research and Life Exper

When you use bbregister, it is expecting the input nii file to represent the actual anatomy of the subject, so it does not surprise me that it does not work that well. I'm not sure what to do about this because a meta analysis image will never have decent anatomy. In theory, it should be alread

They are not in registration. Try running bbregister to create a registration file (lta), then pass the lta to tkregisterfv instead of --regheader On 4/9/18 11:49 PM, Bruce Fischl wrote: How did you generate the registration? And give us the details of what you are trying to register Cheers

Hi Srishti the directory you are in doesn't matter. YOu either need to set SUBJECTS_DIR in the environment, or use --sd to specify the directory that contains your subjects. I think you can also give it the full path to a target volume if you want, but maybe Doug can comment as he knows this

Those commands look ok. My suspicion goes to the use of --regheader. See whether the registration is ok with tkregisterfv --mov negative_allsocial_proportion.nii --regheader --s mni152_subject --surfs --reg reg.deleteme.dat On 04/05/2018 08:34 AM, srishti goel wrote: > Hi, > > I am trying to c

Hi, I am trying to compare my volume maps (negative_allsocial_proportion.nii) to someone else's (SN_like_cortical_lh.nii.gz) who have it on a surface (mni152_subject). So I used the steps for mri_vol2surf command as follows: Commands: mri_vol2surf --src negative_allsocial_proportion.nii --reghead
