Hello,
I’m trying to confirm the contents of two output files from eddy: dwi_post_eddy.eddy_parameters and dwi_post_eddy.eddy_restricted_movement_rms to evaluate movement in my data. Could you please confirm the following?
- The .eddy_parameters file contains per-volume 3 translation / 3 rotation / 10 eddy current estimates (in that order). What is the precise formatting and axis conventions of the file (mm for the translations and radians for the rotations)?
- The .eddy_restricted_movement_rms file has 2 values per volume. Do these correspond to the root-mean-square of the 3 translation and 3 rotation components, respectively (of what it thinks movement was before correction)? What is the .eddy_movement_rms file?
Many thanks for your help.
Regards,
Juan
