Hi Andreia, Nothing will prevent you from running FS6's hippocampal subfields on 5.3-processed subjects, even though I'd recommend processing everything with the same version for the sake of reproducibility. Cheers, /Eugenio

Thank you, Andreia Citando Eugenio Iglesias < e.igles...@bcbl.eu >: Dear Erik / Angela, the atlas in 5.3 was derived from manual annotations on in vivo images that relied largely on geometric rules, and led to volume estimates that did not agree well with histology studies. The new atlas is based on ex vivo MRI and agrees better with histology. Moreover, it also has the option to input higher resolution images (in addition to the standard 1 mm T1), which yield a much better fit of the internal structure of the hippocampus. That said, IMHO you can still publish papers with the old tool; you just need to be careful with the interpretation of the results, and discuss these issues in the submission.

Does this mean that the outputs are completely unreliable and unstable? Should it be parked until the release of version 6?

I am writing a paper using hippocampal subfields (ver 5.3). What is the problem with segmentation using this tool? Is it reliable at least on some of the subfield? When will Freesurfer 6 be released? Thank you Angela Hi Georg, we will be releasing with FreeSurfer 6 a new hippocampal subfield module based on a more accurate atlas built upon ex vivo MRI scans. However, if what you are interested in is the whole hippocampal volume, the results from the new module won't be too different.

I am interested in volumes of the whole hippocampus. Are these volumes still valid and can you estimate when a new version will be available? Can you provide maybe a brief comment on the decision to deprecate the current version?
