Dear FSL experts,
I am in the process of developing an automated preprocessing script for our DTI data. I’ve run “eddy_correct” on the same data set on two different computers (one runs OSX 10.8 and one runs OSX 10.9) and I am getting different results (as observed by taking the difference of these results using fslmaths). Both of these computers are running the same version of FSL (5.0.6) with the same input data and the same exact steps. The reason for two different computers is that a colleague can run my (OSX 10.8) DTI FIT processed data in TBSS for his study.
Any idea why this might be? Or how significant the differences in these results might be? Attached are three images. The first is data from OSX 10.8, the second is from OSX 10.9, and the third is the difference obtained using fslmaths.
Lastly, do you think that this difference may disappear if I were to use the updated “eddy” command (instead of “eddy_correct”)?
Thank you in advance,
Victor
