Dear FreeSurfer experts,
I have 2 questions on the talairach.m3z file generated by recon-all.
1) What exactly does it contain? I read its the displacement field for a non-linear transform from native space to some freesurfer space. But from which input file (or space) to which other one does it transform?
2) What's the file format? Is there a spec somewhere?
Thanks,

Hello all,
Forward this here as it seems relevant to this mailing list. Do not hesitate to circulate this on your institute mailing lists, and ask your collaborators and friends.
Thanks

The neuroimaging quality control (niQC) special interest group (SIG) aims to standardize and develop best practices for niQC and Quality Assurance (QA). Learn more here: tinyurl.com/WeNeedNiQChttp://tinyurl.com/WeNeedNiQC
We invite you to fill this survey, to help us to get a sense of various types of QC/QA that is done in the neuroimaging community. We would like you to cover the "full life-cycle" of neuroimaging research, including but not limited to data collection, preprocessing, intermediate outputs and final results. We request you to provide details into the various QC/QA processes you conduct in your projects. We plan to analyze all the responses from the community to identify the challenges our community is facing, consolidate and review existing research, develop protocols, compile manuals, improve tools, and make recommendations for best practices.

This survey is fully anonymous and we do not track anything. We plan to publicly release your input, in its raw form as well as in various forms of aggregate summaries. In addition to the aforementioned uses, your response will be used for anything else the group would consider necessary in the future to advance its mission. Your participation is voluntary and you can withdraw from this survey anytime.
Hi oTim
sorry, it's not well documented, but the I/O code is distributed if you want to take a look. The .m3z stores a dense deformation field, plus some associated information such as the input and output ras2vox matrices, the resolution of the mesh, etc...
