The new MassHunter DAC B.08 provides supports for the new compression format for profile data, and IMS data.
The support is experimental and limited to GC data.
Compatibility: Tools > Manage Plugins > VUV Reader > Configure > set Wavelength Step Size to 0 results in VUV spectra with wavelengths different from old versions. Old versions maps 0 to 0.05 and the new version maps 0 to 0.2.
The software now automatically detects the missing Microsoft Visual C++ runtime dependencies for MassHunter and Waters Raw data readers, and notifies users.
The new Processing > Extract Ion Peaks as Area Objects replaces the Extract Ion Peaks to Areas plugin included in the previous versions. The new function includes several major improvements. See Ion Peak Detection for more information.
The new Compare Images - Side-by-Side tool adapts the reliable peak region alignment methods from Investigator, enables comprehensive peak matching between two chromatograms, and automates difference detection. The tool provides a set of visualizations that allow users to interactively review two chromatograms, the alignment transformation, and peak matches. See Compare Images (Side-by-Side) for more information.
When File > Load Images in Investigator, the Load Options' Attributes tab lists SNR and Peak Value under Blob/Area for easy access.
The new Compound Finder tool in Investigator allows analysts to detect common and unique compounds across many samples with specialized detection and identification constraints that use chromatographic and mass spectral information to distinguish marker compounds. See Compound Finder for more information.
The new Investigator ML is a plugin tool for supervised pattern recognition and classification. An experimental version of Investigator ML is included in the software. See What's New 2.8 for more information.
File > Import failed on Shimadzu QGD files randomly with error code 0x80030057 after Windows 10 Fall Creator update (version 1709) installed . The error occurred more frequently with 2.7 or 64-bit versions. The fix significantly reduces the occurrence of the problem.
Workaround: Updating Windows 10 to the latest update (version 1803) fixes the problem.
File > Import failed on Thermo Raw files acquired with certain MS/MS modes (e.g. targeted MS/MS) with error code 0x80010105.
Tools > VUV Tool failed with uncaught exception for 2.7r2.2 and later versions.
For example, Edit > CLIC Expression > Select Blobs with an expression "0 & !((Peak_II > 2.2) & (Peak_II > 2.6) & (Peak_I > 28.6)" selected all blobs, but the expression should always return false.
Workaround: Apply ! to individual terms, for example, "0 & (!(Peak_II > 2.2) | !(Peak_II > 2.6) | !(Peak_I > 28.6)".
Processing > Register Image > check Re-detect blobs and uncheck Show the evaluation report > OK, then the Blob Detection UI showed Before Count as 0 no matter what.
The problem is not exposed by any built-in feature in v2.7 or older versions, but may be exposed by a custom report plugin.
Windows XP is no longer supported as a compatible operating system.
Tools > Extract Ion Peaks is replaced by Processing > Extract Ion Peaks as Area Objects.
