Hi Andi - I'm pretty sure we were already planning to change some of the mutualinfo's to corratio's in the next release, so no, this is in no way an official endorsement!

Dear Tracula Team, i noticed that TRACULA uses fsl's flirt with "mutualinfo" as cost function to register the anatomical individual T1 brain (brain_anat.nii.gz) to the MNI152 space T1 template (MNI152_T1_1mm_brain.nii.gz), i.e. for an intramodal registration. I was wondering why "mutualinfo" (which is often used for intermodal registrations) is also used for a an intramodal registration in TRACULA'S implementation rather than e.g. least squares or correlation ratio, the latter being the fsl default. Is "mutualinfo" preferable not only for intermodal (e.g., b0 -> t1) but also for intramodal t1->t1 registrations for your purpose ? - I am just curious to know :) kind regards, andi
