Hi FS experts: I have two questions about FS. (1) Is there a way that can map volume data(.hdr and .img file) to brain surface in FS? (2) I find a way that can extract cortical thickness automatically,first,the statistical significant areas derived from group analysis on qdec are converted to annotation file using mri_surfcluster,then i use mri_annotation2label to convert the annotation file to label file,finally, mri_label2label and mri_anatomical_stats are used to map the label file to each subject and obtain cortical thickness. I want to know if the process is correct.
any help appreciated
1. Yes, mri_vol2surf will do this if you have registered the surfaces to the data (using bbregister for example).
2. Yes, this sounds correct although it's hard to say without all the details
