Weird. I'm curious: Have you tried loading another, existing metric file before mapping (e.g., one that comes with the tutorial, or one you have mapped previously)? It shouldn't matter, but I have seen other features under Surface: Measurements fail, if an existing surface shape file was not already loaded (e.g., like it needed some sort of priming column to exist).
This is not what the error implies, and it should not be necessary. But I have come across this behavior myself, and I don't understand what triggers it. I'm just suggesting easy things to try, in hopes that a quick-fix is found. The only other suggestion that comes to mind is trying options similar to the one you want. For example, mapping to Caret, rather than to a spec with atlas, may not be as easy, but it might be more reliable. You can find the SPM target surface in /usr/local/caret/data_files/fmri_mapping_files/*AVG*SPM*coord. Load it in caret; copy to your directory; and map directly. Save the metric. See if you can get it to work that way, because mapping to spec file writes directly to the metric file, while mapping to caret just stores it in memory; you have to explicitly file: save as metric to save the results. More work, but perhaps fewer obstacles. ;-) On Aug 31, 2013, at 8:02 AM, tony han wrote: > Hi, I'm trying overlay t maps created by spm. I've gone through this many > times without error.
