Hi Bruce,
I would like to confirm the relationship between a few papers and the algorithms they describe.
Does Sequence-independent segmentation of magnetic resonance images (Fischl et al., 2004) describe mri_ca_register, Whole Brain Segmentation: Automated Labeling of Neuroanatomical Structures in the Human Brain (Fischl et al., 2002) describe mri_em_register and High-Resolution Intersubject Averaging and a Coordinate System for the Cortical Surface (Fischl et al., 1999) describe mris_register? And what does Geometry Driven Volumetric Registration (Postelnicu et al., 2007) describe?
Also, I tried to create an account on the Freesurfer website such that I can update the wiki with links to these articles, and received the following message: "You are not allowed to do newaccount on this page. Login and try again.”
For other people reading this, here are links to those articles: Fischl 1999 - https://surfer.nmr.mgh.harvard.edu/ftp/articles/fischl99-morphing.pdf https://surfer.nmr.mgh.harvard.edu/ftp/articles/fischl99-morphing.pdf Fischl 2002 - https://surfer.nmr.mgh.harvard.edu/ftp/articles/fischl02-labeling.pdf https://surfer.nmr.mgh.harvard.edu/ftp/articles/fischl02-labeling.pdf Fischl 2004 - http://www.nmr.mgh.harvard.edu/~fischl/reprints/sequence_independent_segment... http://www.nmr.mgh.harvard.edu/~fischl/reprints/sequence_independent_segmentation_reprint.pdf Postelnicu 2007 - https://surfer.nmr.mgh.harvard.edu/ftp/articles/2007/2007_-_Postelnicu_et_al... https://surfer.nmr.mgh.harvard.edu/ftp/articles/2007/2007_-_Postelnicu_et_al._-_Information_processing_in_medical_imaging_proceedings_of_the_conference.pdf

I see. Thank you very much! Cheers, Ruy

Hi Ruy
they both register to a .gca atlas that is quite a bit more accurate than the MNI. The details are in the 2002 and 2004 papers.

Dear Freesurfer community,
I would like to get a better sense of how mri_em_register and mri_ca_register work. I understand the former is a linear registration and the latter is nonlinear, and that they are both meant to register an individual to a template space (MNI152?).
Would it be possible to update the wiki pages to give more information about the algorithms and cost functions used and other such details? And to provide references to the literature in support of the algorithms if possible?
Thank you. Best regards, Ruy _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
