JASON 4.0

This release brings a number of improvements in various areas.

  • We keep working on analysis of the “arrayed” NMR experiments. Our ROSY processing got even better and is now able to handle T2 and saturation-recovery relaxation experiments.

  • Try our new processing function for reference deconvolution. We have made this advanced NMR processing technique as straightforward and simple as possible. It can improve your spectra in a few simple clicks.

  • Fully automated deconvolution and peak analysis for 1D NMR spectra got even better: it’s now possible to fix selected peak parameters during deconvolution. This gives users more control over analysis and provides more robust results

  • The new compress processing step reduces memory usage and file size.

  • Charts can be manipulated in a similar way to spectra. Most handy mouse modes like zooming and panning can be selected from the floating context toolbar.

  • Multiple improvements for annotations, rules, tables and beyond.

  • As usual, we made a few “under the bonnet” improvements for usability and performance and destroyed a few nasty bugs.

See what the new JASON 4.0 version can do for you.

  • Arrayed and relaxation analysis:

  • ROSY analysis of T2 and saturation-recovery

  • New analysis options can be selected for T2 CPMG and T1 saturation recovery experiments in addition to the T1 inversion recovery. The automatic option selects the correct model based on experiment identification. See corresponding equations in the fitting dialog

  • Relaxation analysis reports either the relaxation rate or time

  • Select either time (top left) or relaxation rate (bottom left) option in ROSY processing. The results table contains T1or R1 data, respectively. The fitting details are visualized for the methyl proton on the right top, and arrayed table contains all integrals used in this example.

  • All traces of a pseudo-2D stack can have the same color

  • NMR processing:

  • Reference deconvolution processing

  • Parameters of the reference deconvolution processing (left) and its use for improving quality of DOSY (right). The same processing with (bottom) and without (top) reference deconvolution was used by fitting each data point of the spectrum.

  • “Compress” processing reduces memory usage and disk storage by removing imaginary components from the processed data. The imaginary components of the original raw data (FID) are retained.

  • During peak fitting, individual peak parameters can be fixed

  • Individual peak parameters can be fixed and not changed during the automatic fitting routine

  • SMILEQ plugin for qNMR:

  • Interactive Summary tables

  • Summary report displays average and standard deviation per run.

  • Annotations:

  • Work better with DOSY plots

  • More annotations shapes

  • Rules:

  • Support predefined peaks/integrals/multiplet lists

  • Spectral cuts can be added to a rule

  • Tables:

  • Tables have titles (see ROSY and Arrayed table examples in Figure 2 above)

  • Further improvements for table resizing

  • Mouse modes (zoom, pan, cursor) for charts

  • Updated interactive integral baseline handling. Easier to set baseline offset and tilt for individual integrals.

  • JASON can export bitmaps with transparent background

  • More consistent handling of Peaks/Integrals/Multiplets analysis parameters.

  • Homonuclear 2D NMR spectra are displayed as square by default

  • Updated Qt 6.5

Please note, macOS Catalina support has been discontinued. Users of macOS Catalina can continue to use JASON 3.2

We also performance-tuned our software and fixed a few bugs.
