SUBJECT: mri_segstats error: dimension mismatch between input volume and seg

Hello FreeSurfer Developers,

I'm attempting to compute average contrast in anatomical ROIs constrained by functional activation, as described on the MultiModal FMRI tutorial (https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultiModalFmriIndividual_freeview), but for some of my subjects I get the following error when I run the mri_segstats command:
 
  ERROR: dimension mismatch between input volume and seg
  input 1 1 145283
  seg   145283 1 1

I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the recon-all.log in case it's of any use. 

1) FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0
2) Platform: CentOS release 6.7 (Final)
3) uname -a: Linux sand 2.6.32-573.3.1.el6.x86_64 #1 SMP Thu Aug 13 22:55:16 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
