To The FSL Experts,
I'm running a First-Level FEAT analysis and in my Post-Stats output I get the following error.
/usr/local/fsl-bin/fsl-4.0.2_x86-64/bin/fslstats thresh_zstat1 -l 0.0001 -R
ERROR:: Empty mask image
ERROR:: Empty mask image
ERROR:: Empty mask image
ERROR:: Empty mask image
ERROR:: Empty mask image
ERROR:: Empty mask image
0.000000 0.000000
Strangely, this error occurs differentially amongst my subjects (i.e., some subjects get it for all contrasts, others only get it for a few). I am not using any Pre-Threshold Masking, so I am not sure what is causing the variability.
Any idea what caused this to occur and ways I could fix it?
With Gratitude,
Dave
