v2.0.0

FastSurfer 2.0

Finally, we are happy to release a new major version of FastSurfer! After thorough testing we now base FastSurfer 2.0 on our VINN (voxel size independent neural network, see https://www.sciencedirect.com/science/article/pii/S1053811922000623 ) and support full brain segmentation on sub-mm MRI (1.5 and 3T) natively. Note, that command line arguments have changed, in order to support inclusion of future modules, such as the cerebellum segmentation which will come soon (at least for 1mm images).

Overall the performance has improved over our - already excellent - first version of FastSurfer (segmentation accuracy, test retest reliability, sensitivity to disease effects and processing time). We also solved an issue previously inherited from FreeSurfer of misaligned cortical areas (pre- and post-central) predominantly in the left hemisphere, by initializing spherical registration with our own code. Furthermore, although experimental, FastSurfer now runs on Windows (CPU via Docker), MacBooks (CPU and natively on GPU ( --device mps ) of the M chips!) and with AMD GPUs, in addition to the Nvidia GPUs or regular CPUs in Linux.

We hope you enjoy this release and please post any issues. While we perform extensive release tests on a hundreds of images from a variety of datasets, there can always be remaining bugs or issues and we appreciate your help in finding and solving them.
