Hi there,

I encountered a similar problem using @auto-tlrc - I have updated Ubuntu an version of AFNI but an still receiving the following error messages:

*********** Warning *************
Dataset centers are 63.587600 mm

parts of the original anatomy gets

input data using this command:
@Align_Centers -base /usr/local/afni/TT_N27+tlrc \\
-dset MI_anat+orig \\
-child ./*.HEAD\\

Then rerun @auto_tlrc using the _shft
version of your datasets.

The anat and func datasets both look good and are well aligned so that\'s not the problem.

Any ideas what the problem might be?

Many thanks
