Hi All,

I hope someone can locate the problem for me. Here is what I did. 1. clicked for "flattened" surface on csurf, which opens tksurfer (I see a flattened surface window) 2. clicked "load overlay" on tksurfer, which asks two inputs. For "Load overlay", I typed in XXX for XXX_000.bfloat Use registration, I used register.dat, which seems OK. 3. Then click OK 4. No functional overlay is made. I mean no functional data show up on the flattened surface.

I looked at the XXX_000.bfloat, which is around 3 Megabytes.

Question: 1. Is there a way that I can verify that *.bfloat is valid? (I used mri_convert XXX.img *.bfloat to create those files) 2. What is a way of creating *.w files from functional data?

Any lead would be welcome. Thanks Nam.
