Fmriprep-docker: Talairaching fails, 3T18yoSchwartzReactN32_as_orig.4dfp.img does not exist!

Hello Everyone,

running fmriprep-docker on a few participants that have no functional data, just anatomical data.

Here’s my command:

fmriprep-docker BIDS derivatives participant --fs-license-file freesurfer_license.txt --low-mem --output-spaces T1w --anat-only

For 5 out of 8 participants, the following happens:

ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm FAILED (p=0.0000, pval=0.0000 < threshold=0.0050)

Manual Talairach alignment may be necessary, or
include the -notal-check flag to skip this test,
making sure the -notal-check flag follows -all
or -autorecon1 in the command string.

and in transforms/talairach_avi.log we see this:

So it seems that fmriprep-docker does not have access to that file, which is available in my local freesurfer installation, but the bigger issue is probably that the standard Talairaching fails.

I think this may be related to this topic and that I may just have to do manual Talairaching before passing my files to fmriprep, but not exactly sure how to do that and whether to change my fmriprep call after doing it.

I should mention that the data are quite poor quality, in my estimation, but the quality does not seem drastically worse between the participants that succeed and those that fail.

Loving fmriprep-docker.




Have you considered running Freesurfer independently? Then you can have more control over these errors. When Freesurfer completes you can use the outputs in fMRIPrep, or if you are just working with T1 images, you can use sMRIPrep.


Hi Steven,

Thanks for your reply. Yes, I could do that. However, even though my use case is fairly minimal here, adopting an alternative workflow seems somewhat at odds with the reproducible computing goals of using fMRIPrep (and sMRIPrep) in the first place.

Question: Is sMRIPrep different from running fMRIprep with --anat-only?



I don’t think this is a big issue, the documentation for fMRIPrep expressly says that pre-existing FreeSurfer outputs can be reused.

In theory, no, but it is possible that the most recent sMRIPrep may be at a newer version than that which is bundled with fMRIPrep.


I guess my point was more that whenever I introduce “manual” steps in addition to just running fMRIprep, those steps are by definition not reproducible.
