Hi Denis Let me CC this also to the HCP-users email list, where others might also learn something from it.
For the MEG1 release we had planned and documented that we would include the hs_file. But then we realized that 1) it has facial details in it (nose and around eyes), which we had agreed in general not to release for identification reasons 2) the high-res T1 anatomical MRIs that are released do not cover the full head and are anyway defaced So in the MEG1 release we already excldued the hs_file from release and in the MEG2 release wel also updated the documentation. The MEG1 documentation is incorrect as it mentions the hs_file in the list of released files. Important to note is that the data that we share in the anatomy package is already coregistered by means of an additional full head (not only brain) T1 scan that we made specifically for the MEG coregistration. So for each subject we match the hs_file to the (scalp and face optimized) full-head MEG specific T1, which we match to the (brain optimized) high-res defaced T1. The full-head MEG specific T1 is not shared, only the high-res defaced T1 is shared. That means that with the released/downloadable data you are not able to replicate the coregistration procedure to the level of accuracy that we have been able to do it with the unreleased T1 data. So you’ll just have to trust us on the coregistration. All coregistration details are shared in the SUBJID_MEG_anatomy_transform.txt text file. I hope those serve the needs of your analysis pipeline. If not, let us know. In case you need a stub file for the pipeline, you can find a hs_file on http://figshare.com/account/projects/3629. It is one from a non-HCP subject that was not recorded at the SLU MEG centre, but it should have the same format. best regards, Robert On 28 Feb 2015, at 15:30, Denis-Alexander Engemann <[email protected]> wrote: > Hi Robert, > > I'm currently working on MNE-Python support for the HCP data. > Having read the manuals and downloaded the unprocessed and processed MEG > data, I realised that the hs_file has apparently been removed from relase I > to release II.
