Rachel,
Those are the transformation matrices required to align each volume to the
reference volume in a 4D dataset. I don't think it would provide a good
measure of data quality.
Peace,
Matt.

Subject: [FSL] eddy_correct
Hi,
I have a DTI dataset for which I would like to create an index of data
quality for each subject (that I could regress out in correlations with
other measures). I was hoping to use an index derived from the output of
the eddy current correction program, but I am not sure how to interpret
the log file. What are the 4 columns and 4 rows for each volume, and what
do the numbers represent?
Thank you,
Rachel
