v1.2.2.6

Release date: 3 December 2023

This is a patch update.

Bug fix

• Support read Input/Output information from sepia_config.m
• Phase DICOM values are rescaled using the max/min values in the data instead of rescale slope/intercept of the NIFTI

Note that the load_config button only supports SEPIA generated sepia_config.m.

v1.2.2.5

Release date: 13 October 2023

This is a patch update.

Bug fix

• Fix the mismatch between SEPIA defined B0 direction and LPCNN when it is not along the z-direction
• Fix the shared library issue when using ROMEO with latest versions of Matlab on Linux (see here)
• Allow user to define atlases' directory paths

v1.2.2.4

Release date: 7 April 2023

This is a patch update.

Bug fix

• Fix bug when importing SEPIA pipeline configuration files (sepia_config.m) to the GUI for using VSHARP and FANSI

v1.2.2.3

Release date: 7 March 2023

This is a patch update.

Bug fix

• Fix bug for using BIDS directory as input where the exported 4D magnitude image does not use the rescale slope and intercept in the NIFTI header for R2star mapping

v1.2.2.2

Release date: 9 February 2023

Bug fix

• Fix bug for using BIDS directory as input where the exported 4D magnitude image does not use the rescale slope and intercept in the NIFTI header

v1.2.2.1

Release date: 2 February 2023

Bug fix

• Fix bug when using optimum weight total field computation with odd matrix size dataset

v1.2.2

Release date: 27 January 2023

Toolbox related

• Make sure all holes inside the ROI mask are filled after the background field removal step
• ROI (brain) mask is applied on the fieldmap regardless of what method is chosen

Bug fix

• Fix bug for non-double type input for MATLAB's strel function

v1.2.1.1

Release date: 12 December 2022

Toolbox related

• Support enabling/disabling GPU processing options for native NDI implementation and FANSI

v1.2.1

Release date: 7 December 2022

Bug fix

• Missing file for R2* mapping with nonlinear least square fitting algorithm
• Error when using image with odd number dimension
• Remove unnecessary requirement of input weighting map for the TKD method from MRI Susceptibility Calculation tool

v1.2.0

Release date: 11 October 2022

This back-to-back update brings you some new exciting features on SEPIA!

Toolbox related

• Support several deep learning based methods (BFRnet, xQSM, QSMnet+ and LP-CNN) on Linux
• Support atlas-based subcortical structure segmentation (CIT168 Reinforcement learning atlas, MuSus-100 and AHEAD) on Linux and macOS
• Integrate R2* mapping toolbox into SEPIA
• New function to further refine brain mask by thresholding high R2* voxels on brain edges
• When magnitude image is used for NDI, the image will be weighted by the intensity of the 99th percentile of the masked voxels instead of the maximum to improve robustness
