Re: [caret-users] problems with Map Volumes
Hi Donna! I am back and was finally able to check. The metric file, as you suspected, only contains the header. I have uploaded the metric file, the functional volume (.hdr and .img in Analyze format) and the fiducial surface. I am working on a Debian Linux platform. Thank you for your help, Marco Hi Marco, The Unknown spec file tag can be safely ignored. My hunch is that the metric file is empty (except perhaps for the header). How big is the file? If 1K, then upload your metric, volume, and fiducial surface here: http://pulvinar.wustl.edu/cgi-bin/upload.cgi You were running Debian Linux, right?

[caret-users] Monkey atlas and stereotaxic coordinates
Hi! I have a question regarding Caret and the monkey atlas. There are 4 different files under Volume Files - Anatomy. Two of them are apparently AC aligned, the two others are aligned with respect to the inter-aural axis. I would like to use the latter ones since this is the stereotaxic coordinate system we are working with. However, there seems to be a misalignment between the surface viewer and the volume viewer whenever I load one of the InterAural_aligned files. The correspondence seems to be OK whenever I load one of the AC_aligned files. Am I doing something wrong? Thanks, Jochen. - Jochen Ditterich, Ph.D. Assistant Professor Center for Neuroscience University of California 1544 Newton Court Davis, CA 95616 USA office: +1 (530) 754-5084 lab:+1 (530) 754-6987 fax:+1 (530) 757-8827

Hi Marco, Could you also upload the topo file? Thanks, Donna On 06/20/2005 04:48 PM, marco tettamanti wrote: Hi Donna! I am back and was finally able to check.
