Version 0.2.0

This release is mostly concerned with correcting field map output and filling in obligatory JSON fields to meet minimal validator requirements.

Added

• New input field for the dataset name in the GUI.
• Creation of the dataset_description.json file with basic (obligatory) contents.
• Removal of JSON sidecars for fieldmap magnitude images.

Changed

• Fieldmap files now don't have the _e2 suffix from dcm2niix.
• General Mapping Window task column was changed to task name column, and the task label is now derived from its content by removing non-alphanumeric characters (rather than taken literally).
