Hi Andi - You're very welcome! I hope you'll find it useful.

That's correct, if you turn off these pre-processing options then trac-all will simply copy your DWIs, gradient table and b-value table from the location that you specify to the dmri/ directory and continue from there.

You can certainly use a past dmrirc file, trac-all is backwards compatible that way. But some of the defaults have changed, and you want to make sure you're not overriding the new defaults unless you have a reason to do so.

I've updated the page of the example dmrirc with the new defaults but also put a link in there to the old defaults so you can compare: http://surfer.nmr.mgh.harvard.edu/fswiki/dmrirc

The tutorial hasn't been updated yet to reflect the 5.2 defaults (ick!) but I'll get to that soon.

Dear Tracula Team,

first, thank you very much for the new version with its many improvements !

I have dwi data (as nii.gz) that have already been unwarped and eddy-corrected, the bvector-textfiles have also been rotated accordingly. So, I guess, when I use TRACULA on these data, I simply set dob0=0, and doeddy=0 and dorotbvecs=0 to indicate that these steps have already been performed outside of tracula, correct  ? (just want to be sure...)

btw. is it safe to use the dmrirc config file from the previous version in the new version ?

thank you very much and kind regards, andi
