External Email - Use Caution        

Hello,

I am running dt_Recon with the following specifications and am running into this issue? I wasn't running into this issue previously. Two changes I made are I added the --eres-save flag and I am running the code on the dev version instead of the freesurfer6.0 version. Any idea what could be contributing to this issue?

I am running the following 

mri_convert image000001.dcm /Volumes/DANIEL/dti_freesurf/diffusion_recons/${subj}.${cond}/dwi.nii.gz



dt_recon --sd /Volumes/DANIEL/dti_freesurf/diffusion_recons --i /Volumes/DANIEL/dti_freesurf/diffusion_recons/${subj}.${cond}/dwi.nii.gz --s ${subj}.${cond} --b dwi.bvals dwi.voxel_space.bvecs --eres-save --o /Volumes/DANIEL/dti_freesurf/dtrecon/${cond}.${subj}


and get an error at this point
