So, I have figured out how to read the surface file into matlab - I first convert the surf file to ascii using mri_convert and then use the read_asc matlab code. When trying to visualize this though, I run into the issue where the curv file and surf file have different dimensions. Is there any

Hi Hannah, I'm not sure I know what you mean. Do you have a label on each subject? If so it will look for it in the subjects label directory. As for the second issue, that sounds like a bug. If you want to send us the subject directory we'll fix it. cheers Bruce On Fri, 19 Mar 2010, Bruehl, H

Hi Hannah, mris_anatomical_stats computes anatomical properties. To map the label, I think you can use mri_label2label. Sita. On Fri, 19 Mar 2010, Bruehl, Hannah wrote: > > Hi there, > > I have got 2 questions: > > 1) is there way to use mris_anatomical_stats to map back the label I have >
