By the looks of it the `cat t1_blood` is not doing what you intend - it seems to be passing the string “cat t1_blood” into oxford_asl rather than reading in the value from the file. I am not quite sure what aspect of the shell that is causing this, but presumably if you manually put the relevant number on the command line it will run correctly - which might at least sanity check whether my diagnosis is correct.

Hello Experts (Michael),

I receive the following error when I run oxford_asl (oxford_asl -i ASL_10TI_diff_mcf.nii.gz -o Oxford_ASL --tis 0.25,0.5,0.75,1,1.25,1.5,1.75,2,2.25,2.5 --t1b `cat t1_blood` --spatial -m M0_mean_brain_mask.nii.gz)

Any idea on how to resolve this error?
