TARQUIN Files

Changes and fixes:

- Spectra can now be manually phased and ppm referenced in the gui after the preprocessing phase.
- Automatic phasing and referencing can be disabled in the advanced fit dialogue.
- Increased the precision of the sampling frequency, transmitter frequency and echo time options from 6 to 12 digits in the advanced fit dialogue. This fixes minor fitting differences between the quick fit and advanced fit dialogues.
- Added row, col and slice controls to the gui for improved navigation of CSI data.
- All CSI voxels can now be viewed and selected/deselected for subsequent analysis.
- Added line-broadening, zero-filling and baseline smoothing options to the gui and command line options. These now influence the exported csv spectra and gnuplot pdf exports. Note - these are postprocessing parameters only and will not change quantitation results.
- The Philips DICOM MRS reader has been improved for dynamic and non-localised data.
- A rare bug causing TARQUIN can hang in the NNLS part of the algorithm has been fixed, thanks to Antonin Skoch for helping out with this.
- Added ext_pdf option for outputting pdf plots of individual fitted basis signals.
- Bug fix for some spectra where initial phasing was 180 degrees out.
- Preprocessing phasing algorithm should now be more robust to poor data.
- The first data point for the simulated signals is now divided by 0.5, reducing the distance between the data and baseline. (see Otting et al 1986 JMR 66, 187-193 for details).
- Eddy current correction is now applied after water removal (when selected) and an option has been added to the gui.
