Dear Freesurfer experts,

I would like to use the Yeo_JNeurophysiol11_FreeSurfer parcellations with my dataset and I am not sure what I have to do. I have used the mris_annot_to_segmentation command but I have the following error:

mris_annot_to_segmentation BASGU lh inflated ./fsaverage5/label/lh.Yeo2011_17Networks_N1000.annot ../Yeo_JNeurophysiol11_MNI152/Yeo2011_17Networks_ColorLUT.txt test reading /freesurfer/BASGU/surf/lh.inflated... reading colortable from annotation file... colortable with 18 entries read (originally MyColorLUT) mri_read(): couldn't determine type of file /freesurfer/BASGU/mri/T1 (null): could not read T1 for template volume

I have a T1.mgz file inside mri/. Where could be the problem? Is this command appropriate?

Thank you in advance, Yolanda
