Hi,

I am a little bit confused on how to proceed to register an individual surface into an Atlas. The 'Caret5 Tutorial: Segmentation, Flattening, and Registration' explains how to perform a spherical registration using the 'Human.colin.L.REGISTER-to-INDIVIDUAL.03-05.71785.spec' file. My questions are:

1) What spec file should I use to register into the right hemisphere?
2) If I choose to register into PALS-B12 atlas, what files should I use?
The answer to both 1) and 2) is use the PALS_B12 LR combo registration target dataset:

http://sumsdb.wustl.edu:8081/sums/archivelist.do?archive_id=6057499

And use the template deform_map included in that dataset to preset your registration parameters. See this page and "Erin's cheat sheet" (linked from the page below) for more details:

http://brainvis.wustl.edu/help/landmarks_core6/landmarks_core6.html

This is what we do. There are separate landmark datasets for the left and right, but they differ very little, and using the LR combo enables you to do cross-hem or inter-hem analyses. The way we look at it, there's very little down side to using the combo dataset, but a lot of up side to doing so. So we routinely use the LR combo now.

We stopped using colin as a registration target a couple of years ago, but some documentation may still refer to it.

Thanks,
Mateus
