It remains puzzling why folks keep using gyral and sulcal parcellations when multiple better options are available now.

Subject: [hcp-users] How to map T1w/T2w contrast to the Desikan-Killiany atlas?
Dear experts,
I am trying to map T1w/T2w contrast myelin maps to the Desikan-Killiany atlas parcellation and have followed the publication by King et al., 2019 for this
(https://doi.org/10.1162/netn_a_00123). They recommend to use the “cifti-create-dense-from-template” and “cifti-parcellate” function, followed by “aparcstats2table” in Freesurfer.
I have T1T2.nii files and tried to first convert them into cifti and then follow the description from above, but I got the warning in the attached file. Moreover, aparcstats2table requires the --meas (measurement) flag which specifies the measure that should be extracted (select from area, volume, thickness, meancurv, foldind, curvind - but not myelin map which is unitless...). I have tried to run it with the default --meas area flag, but Freesurfer automatically looks for the stats file, which is not available in the cifti-T1T2.nii file.
Does anyone have some tips?
Best,
Melissa Thalhammer
