Added 'gaussian'-based thresholding, which automatically selects a masking threshold for a multi-echo sequence when a threshold is not chosen Added NIfTI to BIDS conversion script Added logging functionality with several levels (INFO, WARNING, ERROR) - logs are written to file in the output directory Separated masking functionality into interfaces/nipype_interface_masking.py Added qsmxt_version.py to get the QSMxT version, which is now used to provide version details in the detalis_and_citations.txt file in the output folder Improved BIDS compliance - test datasets now pass using the BIDS validator Fixed a bug where no processors were used in run_2_qsm.py when < 6 GB was available JSON files are now read and written using UTF-8 to avoid problems with UTF-8 characters such as umlauts Some refactoring of the run_2_qsm.py script to make it more readable Removed references to FSL since this is being removed from the QSMxT container; replaced BET with standalone 'bet2' along with a new interface Updated relevant tests and citations
