Hello All

I am working on fsl preprocessed data for simple correlation analysis . I have my data in anat.nii.gz and rest.nii.gz format.
I am doing transformation on my data using following code

@auto_tlrc -base /usr/share/afni/atlases/TT_N27+tlrc -input AnaT.nii.gz /////////// for anatomical

3dresample -dxyz 2.0 2.0 2.0 -prefix pcc_2.nii -inset pcc.nii (pcc.nii is my seed region exract using whereami)

and now transform my resting data using 3dresample -master

3dresample -master pcc_2.nii -prefix rest2 -inset rest.nii.gz ///////////////// for functional

Now my question , Is this transformation correct ?

My correlation map does not overlay proper with their anatomical data. What should I do?

my terminal suggest me to do like this..........when I run transformation on rest.nii.gz
viewing/combining it with volumes of differing obliquity,
you should consider running:
3dWarp -deoblique
on this and other oblique datasets in the same session.
See 3dWarp -help for details.

what is this obliguity? Any other previous need to do seed based connectivity on fsl preprocessed data .Need some suggestion.
And kindly suggest me proper steps for doing transformation. I would love your help.

Thanks
Arvind
