Hi Freesurfer experts, 

For a data set of n=100, selxavg3 is erroring out on 10 subjects (GDDA086, 88, 
89, 91, 93, 94, 95, 96, 97, and 98). It says ERROR: dimension mismatch between 
mask and 1th run. Do you know why freesurfer is having trouble with these 
subjects in particular, and how I can avoid this error?

Thanks for your help,
Anais
