Dear everyone,

I know that this might be not exactly the right place to ask, but I unfortunately did not reach the authors of the publication so far.

I want to work with the evolutionary expansion map by Wei et al. published in Nat Comm (2019; MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://doi.org/10.1038/s41467-019-12764-8). On their website, they provide a download link leading to two mgh files (attached; MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.dutchconnectomelab.nl/wordpress/wp-content/uploads/Wei_et_al_2019_NatureComms.zip). I read them with the Matlab load_mgh.m function provided here (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MghFormat) and it shows a 163842 x 1 vector (which probably corresponds to fsaverage6 I guess...). I now want to convertthe 1D vector back into 3D. I have come across save_mgh.m but don't know what should be put in as M (4x4 vox2ras transform). Any ideas what is the correct way to do that?

Thank you!

Best, Melissa
