Hi FSL team,

I am using eddy_cuda to preprocess my DTI image (32 directions and 3 b0 volumes). Since my computer has limited memory, I cannot preprocess images with a high dimension of 256*256*74*35. I tried to downsample them using a reference image using this command:


flirt -in DTI.nii.gz -ref reference_DTI.nii.gz -o DTI_resampled.nii.gz -applyxfm


Now that I use fslinfo to look at the DTI_resampled.nii.gz, the dimensions are 100*100*74*1225.


How can I ensure that I have 35 volumes rather than 1225.


Thanks,

Sara
