  • Added a new flag to the Extra menu of NUCLEUSinv that allows to set all relaxation times < TE/5 to zero when lsqlin is used for the RTD inversion

Changed

  • Changed the default settings for NMR signal calculation in NUCLEUSmod (more realistic echo time TE of 200µs and the first echo within the time vector is actually TE or TE/2 and not 0)

Fixed

  • Fixed an issue when exporting data from UncertView GUI to NUCLEUSinv main GUI

0.1.14 - 2023-09-27

Added

  • New optional sub GUI FixedTimeView in NUCLEUSinv that allows to fix relaxation times (up to five) if the N free exp. (2-5) option for inversion is chosen and thus only the corresponding amplitudes are fitted
  • New import routine in NUCLEUSinv for the LIAG core scanner (several NMR measurements along a core)

Changed

  • Changed the import routines in NUCLEUSinv for BGR devices (Mouse and Helios) due to device software updates

0.1.13 - 2022-08-11

Changed

  • Changed the way the uncertainty region is displayed when the Multi modal fitting option in NUCLEUSinv is used (now it is [mean-2*std mean+2*std] before it was [min max])

Fixed

Added

  • New ConductView figure in NUCLEUSinv and NUCLEUSmod that shows the hydraulic conductivity and permeability
  • New import routines to NUCLEUSinv for IBAC institute
  • New parameter file values in NUCLEUSinv for the BAM TOM import

Changed

0.1.10 - 2020-09-10

Added

  • Added an updated CHANGELOG.md file to the repository.
  • Added a new Dart import routine. NUCLEUSinv
  • Added a complete status bar to NUCLEUSmod

Changed

Fixed

  • Fixed a nasty minimize / maximize bug for the panels in NUCLEUSmod

0.1.9 - 2019-10-30

Added

  • A last export entry added to the export menu. It always shows the last chosen export routine (speeds up exporting when handling a lot of data). NUCLEUSinv
  • Session files from an older NUCLEUSinv version can now be imported (starting from v.0.1.8). NUCLEUSinv

Changed

  • Within the context menu of the signal list the entry all was renamed to batch. Now it indicates what it is actually doing - batch processing of multiple files. NUCLEUSinv
  • Renamed the InvLaplace inversion option to LU (LU-decomposition) to resolve the confusion with a real inverse Laplace transform. NUCLEUSinv

Fixed

  • Fixed typos and several minor improvements.

0.1.8 - 2019-07-09

Added

  • Added a new color theme: black

Changed

  • Adjusted the dark color theme to new darker background colors
  • Extended the BAM NMR tomograph import filter to take care of background measurements. NUCLEUSinv
  • The Matlab internal lsqnonneg is now the default multi-exponential LSQ option even if the Optimization Toolbox is available. NUCLEUSinv
  • If the Optimization Toolbox is available the user can now choose between lsqnonneg and lsqlin. NUCLEUSinv

Fixed

  • lsqlin was not working properly (default settings adjusted). NUCLEUSinv
  • Fixed the tool tip update when changing the solver or regularization option. NUCLEUSinv
  • Several minor improvements.

0.1.7 - 2019-06-27

Changed

  • Extended the BAM NMR tomograph import routine to handle data files that do not belong to a lift-set (i.e. do not have a z-position defined in the par-file). NUCLEUSinv

Fixed

  • When importing a LIAG project where the calibration file is already inverted, and hence, automatically imported, the relaxation time is now used as Tbulk time for the sample. NUCLEUSinv

0.1.6 - 2019-06-24

Added

  • Added a new PhaseView subGUI to view and change the phase between real and imaginary part of a T2 signal. NUCLEUSinv
  • Added a new import filter for the BAM NMR tomograph. NUCLEUSinv
  • Added an export feature that allows to save T2 raw data into a csv-file (e.g. LIAG format); during save it is possible to overwrite the imaginary part with zeros. NUCLEUSinv

Changed

  • If a T2 signal is imported it is automatically rotated to minimize its imaginary part (the fit incorporates real and imag. part of the signal). NUCLEUSinv
  • The FitStatistics window layout is now in line with the PhaseView layout for consistency reasons. NUCLEUSinv

Fixed

  • If a signal is already inverted and the user changes one of the petro settings, these settings are now stored in the inverted data set too. NUCLEUSinv
  • Many minor improvements mainly regarding a consistent usage experience.

0.1.5 - 2019-03-27

Added

  • Restructured the Process panel and added an additional edit field to set the maximum numbers of echoes per time gate (if gating is activated). NUCLEUSinv
  • Added an option (Extra-Settings-Joint Inversion-menu) to set the inversion bounds for the surface relaxivity (only possible within the joint inversion). NUCLEUSinv
  • Added an option to plot AMP vs TLGM to the Extra-Figures-menu. NUCLEUSinv

Changed

  • Globally renamed rectangular to right angular to avoid any confusion.
  • Restructured the Extra menu to comply with the menu structure of NUCLEUSinv. NUCLEUSmod

Fixed

  • When importing ASCII or EXCEL data the ini-file gets now updated. NUCLEUSinv
  • Export menu now also works for joint inversion data. NUCLEUSinv
  • When switching Expert Mode on / off the availability of the Optimization toolbox is now properly checked and accounted for. NUCLEUSinv
  • Many minor improvements mainly regarding a consistent usage experience. NUCLEUSinv
  • Color theme switching now works (but default theme is used at every startup). NUCLEUSmod

0.1.4 - 2019-03-08

Added

  • Added error weights to the free exp. inversion (new routine fcn_fitFreeT2w). NUCLEUSinv

Changed

  • Due to the new error weights there is no default gating method anymore for the free exp. inversion. NUCLEUSinv

Fixed

  • T1 inversion recovery factor (1 or 2 depending on inversion or saturation recovery) was missing in free exp. inversion and free joint inversion (in Jacobian calculation for angular pores). NUCLEUSinv

0.1.3 - 2019-02-22

Added

  • Added a water content column to the csv-export of the LIAG archive-option NUCLEUSinv
  • Also importing porosity and surface relaxivity information when importing NUCLEUSmod data into NUCLEUSinv. NUCLEUSinv

Changed

  • Changed the y-label of all RTD and PSD axes to volumetric water content [vol %] NUCLEUSinv
  • When using NUCLEUSmod data in NUCLEUSinv and performing a joint inversion, the forward and inverted PSDs are now rescaled to the correct water content to be comparable (added a second rescaling after rescaling by the integral of individual PSDs). NUCLEUSinv
  • Noise is now handled as absolute value instead of percentage. NUCLEUSmod
  • Noise and porosity scaling get handled now within the same routine during forward NMR signal calculation (updateNMRsignals). NUCLEUSmod

Fixed

  • The error vector e is now correctly scaled at the beginning of the joint inversion routine runInversionJoint, therefore accounting for noise and porosity / water content. NUCLEUSinv

0.1.2 - 2019-02-12

Added

  • Added a residual (error) axes to the joint inversion signal axes panel. NUCLEUSinv
  • Added myui information to the session file (this is needed in the future for backward compatibility). NUCLEUSinv

Fixed

  • When a session file with joint inversion data is imported, the GUI is now correctly updated (this check was missing before). NUCLEUSinv
  • When importing a session file, the axes context menus get activated now. NUCLEUSinv
  • When selecting a NMR signal, the joint inversion plots did not get updated when there was already inverted data (fixed in onListboxData). NUCLEUSinv
  • When exporting joint inversion plots the legends were not shown correctly (fixed in exportGraphics). NUCLEUSinv

0.1.1 - 2019-02-12
