Dear Wayne,
We have an idea of what the problem might be and will look into it soon.
Cheers,

Subject: [Freesurfer] kvlGEMSMatlab error: search direction is not a descent direction

Hello FreeSurfer Developers,
I'm attempting to run longitudinal segmentation of hippocampal subfields by using the development version of FreeSurfer, but for some of my subjects I get the following error:
*******************
Global iteration 3
*******************
***** Estimating subject-specific atlas *****
L-BFGS
Verbose: 0
MaximalDeformationStopCriterion: 1e-10
LineSearchMaximalDeformationIntervalStopCriterion: 1e-10

Subject atlas deformation, step 1 of 400
Did one deformation step of max. 0.38685 voxels in 7.733 seconds

Error using kvlGEMSMatlab

Error in kvlStepOptimizer (line 11)
Error in SegmentSubfieldsT1Longitudinal (line 1169)
Does anyone have any thoughts on how to trouble-shoot this one?
1) FreeSurfer version: freesurfer-x86_64-unknown-linux-gnu-dev-20180426
2) Platform: CentOS Linux release 7.4.1708 (Core)
