Your mris_convert command looks correct. I’m able to do the conversion like this with dev version:

mris_convert --annot label/rh.aparc.annot.gii surf/rh.white.gii rh.aparc.annot

I’m wondering which Freesurfer you are running. If you do ‘mris_info surf.gii’, what does it report?

Best,

Hi

I'm trying to create an .annot file from a label.gii file using an HCP fsavarage.surf.gii file (eg mris_convert --annot my_label.label.gii fsaverage_template.L.surf.gii lh.my_annot.annot). However I keep getting the error

** failed to open GIFTI XML file 'fs_L-to-fs_LR_fsaverage.L_LR.spherical_std.164k_fs_L.surf.gii'

mrisReadGIFTIdanum: gifti_read_image() returned NULL

Is there a better way to read/open CIFTI files using mris_convert?

Best and thanks

Karin
