Summary0000130: Measurement frame incorrect for temporary DWI images (Command Line Module)
Description

The temporary dwi file that is written to the /tmp folder during the execution of the Stochastic Tractography Command Line module has a measurement frame that is different from the original dwi file in a way that is inconsistent with the rest of the orientation information in the header.

Additional Information

NRRD Headers for original dwi file and temporary dwi file passed to Stochastic Tractography Module. Notice in the temporary file the measurement frame has changed but the space,space direction, and gradient direction entries have not.
