External Email - Use Caution Hi all,
I have a question regarding checking the output of mri_vol2surf. I am converting a manually segmented volume ROI into a surface label in order to gain information such as cortical thickness. What is the best practice for quality control and checking the surface rendering of the ROI? Are there any protocols or suggestions? As slight changes in projfrac change the output by a large degree, it's difficult to assess what is the closest to the original volume ROI. The suggestions also vary (others say projfrac 0.5, others to use projfrac-max or projdist). The main output statistic I'm interested in cortical thickness of the region (if this influences the options). How do you choose and establish what is the best option? Thanks Marianna
