The whereami program and all other afni programs can generate ROI datasets from the Talairach daemon on the fly. See the help for whereami and 3dcalc for some examples.
The Talairach daemon atlas is based on the Talairach-Tourneaux atlas of a post-mortem tissue analysis on half an individual's brain. There is no MRI template for that exact brain. Instead we use some other template that has been put into "Talairach space" using either a stereotaxic procedure (manual talairaching) or a specific transformation from another space. The TT_N27 dataset distributed with AFNI has been manually talairached. This procedure has some subjectivity, and the output brain will not be the same as the Talairach-Tourneaux atlas brain in any case. The structures will not match exactly, but should match approximately. If you're not seeing this, then there may be another issue in importing the data. Compare with whereami or 3dcalc's output of the same structures.
Consider using other atlases or templates. The ones distributed with afni are typically stored in the same directory as the binary. An easy way to view these datasets is to run afni on that directory:
