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 ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
