Quick question, I ran recon-all with the qcache option and after converting the ?.thickness.fsaverage.mgh to an ascii text file via mri_convert I am noticing some vertices have 0mm thickness and it varies, for example, one subject had 53 vertices labeled as zeros while another had over 9,000 vertices. Is there a method I can use to have a thickness value for each of the 163000+ vertices? I am not sure if this is a possible registration issue to mni305. 

Thanks in advance,

Taha
