It still doesn't work.  The error message is the same as the one I
previously sent.  Am I doing something wrong?

mri_surf2surf --srcsubject $SUBJECT --sval-xyz smhead.surf --trgsubject
ico --trgicoorder 7 --tval
/imaging/dw01/simulation/subjects/p002/surf/p002_outer_skin --tval-xyz
--hemi lh



  

Try it without the --sval (it will get the sval from the xyz in the
surface).

Hi Doug,

Thanks.

I tried this and got the following:

[dw01@lws003 test2bem]$ mri_surf2surf --srcsubject $SUBJECT --sval-xyz
smhead.surf --sval /imaging/dw01/simulation/subjects/p002/surf/
--trgsubject ico --trgicoorder 7 --tval
/imaging/dw01/simulation/subjects/p002/surf/p002_outer_skin --tval-xyz

Try this instead:

mri_surf2surf --srcsubject $SUBJECT
--sval-xyz $SUBJECTS_DIR/$SUBJECT/surf/lh.smseghead
--trgsubject ico
--tval $SUBJECTS_DIR/$SUBJECT/surf/$SUBJECT'_outer_skull' --tval-xyz
--hemi lh


It is admittedly a little obtuse. mri_surf2surf was originally
programmed to accept surface overlay and not surfaces themselves.
--sval-xyz indicates that the input is a surface. --tval-xyz indicates
that the output should be saved as a surface instead of an overlay.

Hi,

I have a question (I believe about mri_surf2surf).  First, I'll
describe
my goal:

I want to take a surface created with mri_tessellate and modified with
mris_smooth and convert it to an isomorphic equally subdivided
icosahedron
(like mri_watershed creates).

e.g. take the lh.smseghead created by mkheadsurf and resample it:

mri_surf2surf --srcsubject $SUBJECT --srcsurfval
$SUBJECTS_DIR/$SUBJECT/surf/lh.smseghead --src_type surf --trgsubject
ico
--trgsurfval $SUBJECTS_DIR/$SUBJECT/surf/$SUBJECT'_outer_skull' --hemi
lh

I get the following error:

ERROR: could not determine type of
/imaging/dw01/simulation/subjects/subject_02/surf/lh.smseghead

If this is possible, I want to know how I can correct my command.

Cheers,
Dan
