Hi everyone!
I am starting a study and I am not able to overlay the fMRI data on the anatomical one, using FSLView.
I have an AFNI dataset and I converted it to NIfTI using 3dAFNItoNIFTI. When converting it, I found out that the fmri data were oblique with respect to the anatomical image. So I run 3dWarp -deoblique on them and then converted them.
At this point I tried to flip them using fslswapdim and visualizing them with fslview but I got an error: unable to load incompatible overlay!
So I run fslsize and found out that the data have different dimensions:
Anatomical after 3dWarp -deoblique:
dim1 310
dim2 320
dim3 256
dim4 1
pixdim1 0.750000
pixdim2 0.750000
pixdim3 0.750000
pixdim4 0.000000
Functional after 3dWarp -deoblique:
dim1 66
dim2 66
dim3 38
dim4 190
pixdim1 3.750000
pixdim2 3.750000
pixdim3 3.750000
pixdim4 2.000000
How can I make them to have the same size?
Thank you so much,
Carlotta.
