Hi FreeSurfer Team,
I was hoping I might be able to get some information about TalAviQA. I have read that this number is a spatial correlation between the input image and the image transformed to the Talairach atlas. Is that correct? Can you tell me any more about how this correlation is calculated?
I hope this isn't a silly question, but besides the Euler numbers and the mris_jacobian command, are there any other quantitative metrics of how much warping was necessary for a particular subject's recon-all? Also, are there multiple ways to run mris_jacobian such that you can get information beyond lh/rh.white.preaparc? Might you be able to offer any hints as to other files to feed the mris_jacobian command besides 'mris_jacobian ../surf/l(r)h.white.preaparc ../surf/l(r)h.sphere.reg ../surf/l(r)h.jacobian_white'
Finally, is there a complete set of documentation somewhere for the QA Tools package of scripts? Are these scripts up to date and compatible with Freesurfer 6? https://surfer.nmr.mgh.harvard.edu/fswiki/QATools suggests that v1.1 came out in 2012 and the current release for download is v1.2...
Thanks for your time, thanks for your efforts creating and maintaining Freesurfer! Alex
cc'ing Avi who is the best person to shed light on TalAviQA. Not sure about the jacobian answer
