External Email - Use Caution *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 MaximumNumberOfIterations: 1000 BFGS-MaximumMemoryLength: 12 Subject atlas deformation, step 1 of 400 Did one deformation step of max. 0.38685 voxels in 7.733 seconds

Subject atlas deformation, step 2 of 400 Error using kvlGEMSMatlab /autofs/space/panamint_005/users/iglesias/software/freesurfer/GEMS2/ kvlAtlasMeshDeformationOptimizer.cxx:327: itk::ERROR: AtlasMeshDeformationLBFGSOptimizer(0x2b53b9427df0): search direction is not a descent direction!
Error in kvlStepOptimizer (line 11) Error in SegmentSubfieldsT1Longitudinal (line 1169)
Does anyone have any thoughts on how to trouble-shoot this one?
