You can look in the recon-all.log file to see how wmparc.mgz is created.
Which version of FS are you using? If V6, then the command will be
mri_aparc2aseg. If V7, then it will mri_surf2volseg. Either way, modify
the command to use your annotation.

External Email - Use Caution
Dear Freesurfer experts,
I have a surface parcellation (annotation) with 318 labels; see
attachments for each hemi. I wish to extract volume-based features (FA
and MD) corresponding to these 318 labels. I believe I should perform
something like surf2vol to extend the labels into FA space. However,
my surface parcellation is not a surface overlay (which I need for
--so). Any other ways to do this?
I wish for the output to be a single volume-based parcellation of 318
labels, corresponding to the two surface parcellation annotation
files. I will then use this output to get FA measures for each of the
318 regions.
Thank you,
Ellen
