External Email - Use Caution 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 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 attached a modified version using 'join' that runs much faster, only has some compatibility issues with Mac. >time labels_intersect precentral.label frontal.label out1.label > /dev/null real 1m41.862s user 0m31.052s sys 0m30.757s >time bash bash_labels_intersect.sh precentral.label frontal.label out2.label real 0m0.193s user 0m0.118s sys 0m0.015s >diff -w out1.label out2.label > Thank you and best wishes Cornelius -- Cornelius Kronlage Assistenzarzt Klinik für Neurologie | Neurologie mit Schwerpunkt Epileptologie Universitätsklinikum Tübingen Hoppe-Seyler-Str. 3 | 72076 Tübingen
