oh yeah, you're right. Unless no tal exists, in which case it's "volume scanner".

actually, I think it needs to be talairach coords. The next version will use indicies (and so will be independent of the tal transform).

you need to use the "volume scanner coords" in tkmedit, not the indices.

Hi surfers,

I experience a problem during the first step of the create surface routine : fill white matter. Specifically, the ponscall.dat file in mri/tmp is empty and at the start of step two (tessellate RH white matter) I'm asked to confirm that "the images in .../mri/filled/COR-0 cannot be found .... wmfill first."

I have already tried to enter the coordinates of the corpus callosum and the pons manually (paying attention to the fact that xTal = coronal, yTal = horizontal, zTal = saggital + to make sure the cc is disconnected), without result... (I use the values in the Volume Index, no Talairachs).

Do I have to pay attention to other things when entering coordinates manually?

Or does anyone of you have an idea about what's going wrong?

Any help appreciated!

Thanks and enjoy the holidays,
