Hi,<br><br>I would like to try running recon-all for some subjects using two source images in combination. The first image is a FLAIR with dimensions 288x288x30, while the second is a T1 with dimensions 256x256x165. Furthermore, the each FLAIR voxel has dimensions of 0.79x0.79x4.5 mm, while each T1 voxel has dimensions 1x1x1 mm.<br>
<br>I tried running the following command:<br><br><b>recon-all -i FLAIR/FLAIR_P00004210_S0001.nii -i T1/T1_P00004210_S0001.nii -subjid FreeSurfer_FLAIR</b> <br><br>But I got the following error message: <br><br><b>ERROR: inputs have mismatched dimensions!</b><br>
<br>Is there an inbuilt command in FreeSurfer that will override this error message and perform a linear registration of the two images into the same space automatically, or do I need to perform the registration manually before starting with recon-all?<br>
<br>Thank you,<br>Deirdre<br>
