Hello FreeSurfer Developers,

I am trying to follow the diffusion processing pipeline describe in this tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/DiffusionV6.0#dMRIDataA...

However, I keep getting an error when using dt_recon. For background, my input is 1700 dicom images. The code seems to run the Eddy/Motion Correct part. Once it reaches Fitting Tensors, I get the following messages:

I saw a previous post with a similar error, however there was no answer to it: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg56652.html. My computer has almost 20 GB of free space, so there should be space for the resulting files to be created.

Freesurfer version: freesurfer-Linux-centos6_x86-stable-pub-v6.0.0-2beb96c

Platform: Linux (Ubuntu) subsystem for Window 10

Thank you,
