Hi Donna and John,I was running into a strange observation when using the "Surface Outline" function in Caret's MRI viewer. When applying it to your macaque cortex datasets there seems to be a relatively substantial misalignment between the MRI and the layer 4 surface model, especially for the left hemisphere. Have you noticed this before or am I doing something wrong?
There are multiple versions of the macauqe fiducial surface and the volume data in SumsDB, and not all of them are properly aligned with one another. Below are screen shots from a combination that is well aligned.
The relevant data files are accessible from the Atlases directory, along the top row of the SumsDB home page. Select the MACAQUE/ directory (http://sumsdb.wustl.edu/sums/directory.do? dir_id=679531&dir_name=MACAQUE), then the hemisphere(s) you want. You can then view the data in WebCaret and download what you like.
Alternatively, you can directly download the following two surfaces and one volume that should be well aligned:

Let us know if alignment problems persist or if there are other issues that arise.
