Hello FSL users,
Some of my attempts using verbena for DSC processing have failed; and i have noticed the "igamc underflow error" message shown on the terminal, but not sure if that is the cause. There is no outputs in the vm and vm_mv folders, but the modelfree results seem fine.
Here is the command i used,
verbena -i ${out_dir}/$sub/unwarp/unwarp.nii.gz -m ${out_dir}/$sub/unwarp/unwarpbrain_mask.nii.gz -a ${out_dir}/$sub/unwarp/aif.nii.gz -aifconc -tr 1.59 -te 0.0146 -modelfreeinit -mv -o ${out_dir}/$sub/unwarp
, where the unwarp.nii.gz is the 4D dsc data.
Thank you,
Ping
