Hi,

The problem was found. Apparently you have to specify the extension '.tif' for the template file, otherwise you get the error shown in the message below. So to make a template of the right hemisphere from, for example, the Freesurfer example data 'bert', the following command seems to be working:

mris_make_template rh sphere bert template.tif

Cheers, Janne

Hi,

I asked about these things earlier (see http://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2004-June/000134.ht ml), but we're still having troubles. We're trying to create our own template for the registration procedure. The idea was to make the template by first registering all the other template surfaces to one single surface and proceed from there. We've tried the method 'mris_make_template', which we've interpreted to be the one intended for the procedure. However, we're getting an error when, for example, attempting to create a template from the Freesurfer example data 'bert':

mris_make_template rh sphere bert template_test

<OUTPUT> creating new parameterization... processing subject bert reading spherical surface /data/hamalja/freesurfer/subjects/bert/surf/rh.sphere... computing parameterization for surface /data/hamalja/freesurfer/subjects/bert/surf/rh.inflated... computing parameterization for surface /data/hamalja/freesurfer/subjects/bert/surf/rh.sulc... computing parameterization for surface /data/hamalja/freesurfer/subjects/bert/surf/rh.smoothwm... writing updated template to template_test...

So, are we doing something wrong, or could there perhaps be something wrong with our installation? Any help would be appreciated. Thanks in advance,
