Re: [Freesurfer] [TRACULA] Issue with registration to diffusion space

Hi Anastasia,

It looks as though some but now all have updated -

Hi Lauren - Can you run "ls -l" in this subject's dmri/xfms/ and check the creation dates of the files to see if they were updated?

Hi Anastasia,

I just re-ran the trac-preproc script with the bbregister command set to 0 in the configuration file, and I'm afraid I got the same erroneous result. Do you have any other ideas as to where the problem could be coming from?

Lauren

Hi Lauren - I suspect that TRACULA is not using your corrected bbregister registration file. That's because the -intra step in TRACULA doesn't just run bbregister, but also does a bunch of other things with the output of bbregister, like transform, invert, and compose a bunch of registration files. Because you skipped the -intra step, these things were not updated. You can temporarily comment out the bbregister command in the trac-preproc script, and run the -intra step so that it updates all those other files.

Hope this helps!

Hello experts,

I'm in the midst of processing a series of subjects for analysis in TRACULA, and have come across one subject which doesn't seem to be registering correctly. I edited the registration manually using tkregister2 (photos "lowb_brain_anat" and "T1" attached), and then ran bbregister myself using this new registration. I then re-ran TRACULA -prep starting at the inter-subject registration, skipping the steps up to and including intra-subject registration (using the new files from my manual bbregister). However, the registration still doesn't seem to have completed correctly (see photos "aparc+aseg_vs_FA_cor and "aparc+asef_vs_FA_sag"). Any advice as to why this bad registration could still be happening and how to correct it?

Thanks, Lauren Ostrowski
