Hi,
I keep getting this warning when trying to run 3dDeconvolve on one run of fMRI data:
*+ WARNING: Input polort=1; Longest run=514.8 s; Recommended minimum polort=4
I got this initially when I set “-polort A” but have since changed it to “-polort 4” as per the recommended minimum. I’ve been able to successfully run 3dDeconvolve with a two run version of the task and using “-polort A”, but keep getting this warning when running 3dDeconvolve on only 1 run. My script is pasted below.
