Are those backslashes ("") in your command-line? If so, try removing them.

Hi there,

I've got a sample of subjects with T1 and T2 scans that I'm trying to compare. I did the entire longitudinal stream protocol, and am now doing the paired analysis protocol. I'm stuck on the Spatial Smoothing step: I've only gotten either a ">" or a message reading, "ERROR: Option -sval unknown." Is there any reason why? Thanks, -Reva
