Sure! The more slices the better __ Maybe it would be possible to share norm.mgz (which is skull stripped and thus deidentified) and the segmentation? Or maybe even crop norm.mgz around the thalami with Freeview? Cheers, /E

Dear Eugenio,
thank you for your response. Unfortunately it is not possible to share the whole subject. Would it be helpful to send you more screenshots of all three views (coronal, sagittal, axial) with different mask opacities?
Kind regards, Franziska

Hi Cornelius
I found something that computes the overlap of labels across the same vertex when doing some research about this, not sure if this is what you mean:
https://secure-web.cisco.com/116MIwNJShgHoW9J9evPl5bCi0xgcx82bMJ48_l7VTkyo4r...
See specifically: --nhits <nhits_file> This option creates a diagnostic file showing whether the cumulative effect of all the label files happens to assign more than one label to each vertex. The output file is a FreeSurferhttps://secure-web.cisco.com/1QIgJhgEjv5N9NM6Uh6927wVezy6eduY2p7_2aAiUh0J8fE_QRjLZ5IwPbIC4gnKD6g26N7TVbaIwYLg5BdgQSCFY1LmWY1cDfBL-R49zhRDt-6TzW_S84l6Z-4U3QS-SBlj8HR82qBl0HjcfjS2buz3mtuIQomiilbbafLXzRw1wQSaUnmj1OITA84m-fC1C8HrL430p2kCyyotFmJGKKwiiXBgMYlYljQIFiqINhAJFUVeI9kbMvioqTgmQZvjStJ8ARcmqHgrk_981OzG8NQ/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FFreeSurfer 'overlay' format file, in which each vertex has an associated value, in this case the count of labels assigned to that vertex. This can be displayed in tksurfer as a color. Setting fthresh to 1.5 will distinguish good vertices (count<=1) from bad (count>=2).
I know there is also a command merge_labels that may help?

Dear freesurfers,
is there an elegant way of computing the intersection or overlap of different labels or - which would be even more useful for my application - annotations?
I only managed to find labels_intersect (which appears to be from MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://secure-web.cisco.com/16WQ5tQQPY74lwcUD6e-u4HAYMeACJcAQ4y9i44WDTIAnwC...https://secure-web.cisco.com/12D3ntbm8RDBV366hh41UjEkFWk2mrjQHSMiY8WEom0naUegbdbmI9Bk7UNIwOTDDV40505y4xUMucZzUUWAKig63gNPrAZl0JMYNPDR9rlE4fUcOuQETynMWSKJG67sRNzzZQq8VF7AEsupWpjkrPP17ola-zMVT-3GDtM_dSs0-j76spejYlLevtumd4uKC8BNXwnxiW47uZxy5cBV4IPlI1yL8DP4GKO7QCjCWHuSjiE1xMapPwxOxVnVfHUKM/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg11344.html ) which is awfully slow. In case this is of use for anyone else, I att ached a modified version using 'join' that runs much faster, only has some compatibility issues with Mac.
