Hi everyone,
I have started using CAT12 to perform a lognitudinal morphometric study. I would like to use the cortical thickness measure provided by CAT to test my hypotheses. I am playing around a little bit to see the results of segmentation/surface reconstruction for some subjects, and to check the QA for my acquisition.
I can correctly visualize the central surface and the thickness using freeview, however I would like to check if the surface actually follow the grey matter boundary. To do so, I would need to overlay the surface onto the correct T1, however, I can not find the correct T1 to use for this check: the T1 that I used as input to CAT is in a different space than the surface, as it is the average T1 and all the other volume that can be found in the output of CAT.
Is there a volume that I can use to check for the quality of the surface ?
