For all my subjects I am trying to process on 17.f when I run

Preprocessing: default preprocessing pipeline for volume-based analyses (direct normalization to NMNI space), then remove slice timing correction

I get the following error.  I hit continue but I do not think that it ignores the error and continues to run.  

The following modules did not run:
Failed: Realign & Unwarp

ERROR DESCRIPTION:

Error using MATLABbatch system
Job execution failed. The full log of this run can be found in MATLAB command window, starting with the lines (look for the line showing the exact #job as displayed in this error message)
------------------
Running job #1
------------------
CONN v.17.f
SPM12 + DEM FieldMap MEEGtools
Matlab v.2017b
storage: 865.9Gb available
spm @ /Applications/Imaging/spm12
conn @ /Applications/Imaging/conn

File background and history:  Scanning on a 3T Philips, burn cd from scanner, import scanner dicom into Oxirix and export images into a single dicom file. 
Convert images to NII using MRIcroGL/MRIcro.app.  Tried using both the dicom image file and the nii image file in CONN and get same error. Tried on multiple subjects (ran individually) and get the same error. Suggestions?  I also moved CONN up in the Matlab path (above SPM EEG tools) and same error.

Update: I ran on a different computer with 17d and did not get the error.
