GC IMAGE - GC Image GCxGC Edition - User Guide 2024R2

New Features and Improvements in Release 2.4

GC Image GCxGC Edition Release 2.4 (September 2013) has many new features and improvements. See the GC Image GCxGC Edition User Guide for full documentation. GC Image GCxGC Edition Release 2.4 requires Microsoft Windows XP Service Pack 3 or later operating system. GC Image GCxGC Edition Release 2.4 (64-bit) requires a 64-bit Windows operating system. For Agilent MassHunter or JEOL AccuTOF users, the software requires Microsoft .Net Framework 4.0 or later.

64-bit Support

GC Image R2.4 has a 64-bit version that can take advantage of the full memory space provided a 64-bit Windows operating system and can handle very large data sets.

New and Improved Operations and I/O Support for HRMS and MS/MS

GC Image R2.4 has new and improved I/O facilities for high-resolution MS and MS/MS data, including:

• Exporting and importing mass calibration settings with other configurations.
• Working with profile spectra in JEOL AccuTOF 4G data files.
• Supporting multiple MS/MS scan groups through interpolation.
• Supporting mixed Profile and MS/MS scan groups.
• Supporting MS/MS data files acquired with Shimadzu GCMSsolution.
• Improved mzXML and mzData readers with MS/MS support.

Support for HRMS and MS/MS data is provided only in the HRMS Edition software.

New and Improved Operations with CLIC Expression

GC Image R2.4 expands the Auto CLIC feature to support more constraints. When adding blobs to a template, the software can automatically generates Qualifier CLIC based on retention times, linear retention indices, spectral match factors and reverse match factors. In addition, the software introduces several new built-in CLIC functions, including:

• LRI(1|2), that returns the retention index of a pixel or a blob apex if linear retention index calibration is configured.
• IDOf("< name >", BLOB|AREA), that returns the id of a blob or area object with the specified name.
• FeatureAtArea(id, "< feature >"), that allows access to computed attributes of other area objects.
• HasMS(), that tests if spectral data are available.
• Logical functions: IF(), NOT(), OR(), AND().
• STRMatch(pattern, string), that tests if a string matches with the specified wildcard pattern.
• A more complete set of math functions.

Also, CLIC Calculator's key pad has two new buttons, Space and Comma.

New and Improved Operations in Image Investigator™

Image Investigator in GC Image R2.4 supports:

• Saving and loading an existing analysis without reloading all chromatograms.
• Updating an auto-generated feature template by removing or adding some chromatograms.
• Normalization options when auto generating a feature template.
• Using batches as class assignment when investigating chromatograms in a project.
• Keeping compound names assigned by library search when auto generating a feature template.

New and Improved Operations with Methods

Methods in GC Image R2.4 supports:

• Skipping baseline correction as a part of a method.
• Exporting the image as CSV or Text MS files as a part of a method.
• Update option when applying a LRI table.
• Update option when matching a template.

New and Improved Slice Report (SIMDIS)

Slice Report in GC Image R2.4 supports:

• Sorting region-based groups by ID, name, or description.
• Sample chromatogram as a part of a slice report.
• Region-based group table with names and descriptions as a part of a slice report.

New and Improved I/O Support

GC Image R2.4 has new and improved I/O facilities, including:

• Support for selecting positive/negative polarity when importing MassHunter data files.
• Support for selecting a data channel when importing MassHunter data files acquired with multiple detectors.
• Support for DANI's .TOF files.
• Support for Shimadzu LCD files (The support is experimental and requires Shimadzu LCMSsolution Version 3 installed).
• Displaying correct retention times for chromatograms cropped at importing.

Also, GC Image R2.4 can import and display chromatograms acquired with variable modulation. The feature of variable modulation is experimental and should be used with caution.

New and Improved Operations

GC Image R2.4 has many new and improved operations, including:

• Better axes in the Image Viewer and Summary Report.
• F2 hot key for copying now works with MS chromatogram views.
• Save Blob Table and Blob Set Table as a XLS file.
• Update Template now asks users to choose the update option.
• Save button on the tool bar of Template Object Table.
• Delete hot key now works in Template Object Table.
• The behavior of Library Search action is now based on current selection.
• Better UI layout for Shift Phase, Arithmetic Operations, and Run Script.
• 3D View now has the view and control panel in a single dialog.
• GC Project now has new method menus and better menu organization.

Also, the software has several new and enhanced features for user support, including:

• About dialog displays the software license and update information if available.
• Now users can request a trial license activation code online through a link on the Trial License dialog.
• A new Help menu item directs users to the online user forum site.
• A Toolbox UI for delivering standalone user-requested or experimental utilities.
