New Features and Improvements in Version 2020
GC Image GCxGC Edition 2020 has many new features and improvements. See
the GC Image GCxGC Edition Users' Guide for full
What's New in Version 2020 Release 1 (July 2020)
Version 2020R1 includes a new 64-bit framework that provides
improved performance and system stability for all operations when
processing data larger than 2GB. Due to the new framework, the
software no longer supports the Microsoft Windows Vista or older
Version 2020R1 introduces the Command Line interface
that allows processing a single raw data file or re-processing a
chromatographic image with a Method
or scripting. The interface can be used to create workflows that
integrate multiple tools or software for automating routine analysis
or complicated processing with a large number of data files.
Version 2020R1 has new improvements on generic
retention index calibration especially
for batch processing, including:
- A new Retention Index Method (.gcrm) file that allows
the user to export and import the RI table and settings together
either manually or through a Method;
- Default retention index calibration settings now can be
configured and exported through Configure
> Settings along with other settings;
- Import and Refresh an RI table now keeps current settings;
- A clear error message, instead of an empty table, is
displayed if a linked RI table file is empty or invalid.
In addition, the software now supports
- Base 10, in addition to natural log, for the log-linear
- Converting other retention properties of a blob to retention
indices with two new CLIC
functions, LRI1() and LRI2().
Version 2020R1 has two new filters for
Processing > Extract Ion
Peaks as Areas:
- New Min Qualifier Ion Count filter that allows the
user to specify the minimum number of apexing ions required;
- New CLIC Filter that allows the user to specify a
customized constraint using all properties computed for a targeted
ion apex peak, for example, retention times or a combination of peak
width and qualifier ions.
The operation now can be added to a Method,
and supported by batch processing with Project
or the Command Line interface.
In addition, the Context
MS mode has the following improvements to make it easier to examine
spectra deconvolved by the operation, including:
- Reference MS, where the deconvolved spectrum are
stored, is loaded to the MS View automatically;
- Only the primary spectra are set to be visible by default for
a less cluttered display;
- A spectrum can be set to Active and Visible separately to
allow fast toggling of the displayed spectra in MS Viewer.
Version 2020R1 has new improvements for
- Spectra view in the Compounds Perspective
now supports sending a selected spectrum to the NIST Library for
- Compound Finder
now displays the results next to the main perspectives, which allows
cross examining the information of resulting compounds from the main
Version 2020R1 has other improved operations, including:
Blob Detection now has a new Apply and Save as Defaults
button that allows the user to save detection settings as the default
configuration. The button replaces the old Set-to-Configuration
option and question.
Blob Detection now sets only the Min threshold, instead of
both Min and Max thresholds, by default when SNR or other threshold-based
suggested properties are added.
- The software now supports smaller font sizes (i.e. 4 - 7)
than 8 for Text
annotation on small chromatogram images.
