Would you mind sharing some images, showing how/where the LGN is oversegmented, please? It would be very helpful to better understand the problem. Kind regards, /Eugenio -- Juan Eugenio Iglesias http://secure-web.cisco.com/1QoIHWx0-hhjdJ0DHeheLrwQhSDhTxo2XFs4j5D-wBNZ1ih6sPPQa2t13EECj5Df99U7LY8RGoIyAjBi2MQ6IZNBKFqsEhCaCedMvm2IrHmMbqabcwaZSor4gBsQob8wCMYvn9C08bR0VCspvYjMVmnfzcHedoy8pxV_u8NaU2hAXrVAeJfeNJsalCsA-zW0CrpGybs4sh3Bq_qm7u6iiZ8WuDy9EsvTFAgexWCNkM0RRt09ySDyAVsp3BRPW6013DbwJT7tWomQi_dquOdGaCB5X6jiByiu-OSW67rhdMDsJ9heMidoHybr-QiQcCYon/http%3A%2F%2Fwww.jeiglesias.com From: freesurfer-boun...@nmr.mgh.harvard.edu <mailto:freesurfer-boun...@nmr.mgh.harvard.edu> <freesurfer-boun...@nmr.mgh.harvard.edu <mailto:freesurfer-boun...@nmr.mgh.harvard.edu> > on behalf of Katharina von Kriegstein <katharina.von_kriegst...@tu-dresden.de <mailto:katharina.von_kriegst...@tu-dresden.de> > Date: Monday, February 26, 2024 at 5:16 AM To: freesurfer@nmr.mgh.harvard.edu <mailto:freesurfer@nmr.mgh.harvard.edu> <freesurfer@nmr.mgh.harvard.edu <mailto:freesurfer@nmr.mgh.harvard.edu> > Cc: Chelsea Jarrett <chelsea.jarr...@tu-dresden.de <mailto:chelsea.jarr...@tu-dresden.de> >, Hannes Ruge <hannes.r...@tu-dresden.de <mailto:hannes.r...@tu-dresden.de> > Subject: [Freesurfer] Too large volumes thalamus segmentation in version 7.2 Dear List, We are using the thalamic segmentation and have encountered too large nuclei volumes. We are aware of the bug in previous Freesurfer versions reported here https://secure-web.cisco.com/1IbBjsoyLKSxbo51anCmnlGJ7AZlAHQC-iMHoutsQKt5emo sDTMTW0h4Zr4x8Fc3T9saf02_wRcDR4wCu6Bbm5CK3KosJDQPCWk4MW2zsevWOrjnSh5jM2PW-7j yJglBbcd_IBcCbhj_w5aPS8oA8bdObZ2aQtO0bkdTaFt-ZXIN_6DMcK3rdono_RSBISep330s0lC -NWLL2L995DdOML88nS0YAsEYEHjhvIbvRvggLG_elezRlsrqWsMD5NxHP-plyRmABs74rTKJp7V aC_-aW9rIG1-vzaz7ad-hqGB27LbybsrMc4ojdXtNr86G-/https%3A%2F%2Ffreesurfer.net% 2Ffswiki%2FThalamicNuclei . In version 7.2 this bug is fixed. Does someone else have similar difficulties with too large volumes? For example, our LGN is 259 mm3 (left) and 304 mm3 (right), while in the original paper for the thalamus segmentation (Iglesias et al. 2018), it is 124 mm3, which is close to the size reported by histological studies. Thanks for reading!
