p:IGI+/Metis version 2.0 release notes

Version 2.0 of our software is a significant upgrade for both p:IGI+ and Metis. It is a strongly recommended upgrade, that involves significant changes to the underlying data storage, offering the opportunity to further improve things moving forward.

The changes made require a ‘migration’ of existing projects and databases to the new format (preserving the original .pigi /.Metis file). The process to migrate older projects to version 2.0 will begin automatically when selecting to open a previous version project file in the new software. A separate application will start to run the migration, and then, as p:IGI+/Transform 2.0 has been registered to open .pigi2/.metis2 files, once finished p:IGI+/Transform v2.0  will launch opening the migrated project. The need for project migration means projects created/edited in version 2.0+ will no longer be usable in version 1.xx of the software.

Migrations are not supported on network drives. Please copy your projects to a local / OneDrive folder before conversion. They can then be used from network drives once migrated.

Full details of the release notes, which are extensive, is available as a pdf. A high level summary of the features is provided below.

New/Improved features (p:IGI+ and Metis Transform)

  • Performance has been improved across the software. Memory usage has been reduced in many places, and speed enhanced in some. This remains a work in progress. There are known performance issues when exporting all data from large projects (>30,000 samples)
  • The .pigi2 and .metis2 file extensions will be registered with Windows as part of the installation, meaning the files can be double clicked to open in the applications, and will have the p:IGI+ and Metis icons associated with them
  • Date-time support has been added across the property model and software features
  • Sites on maps can now be labelled
  • Sample data can be exported directly in Excel format from p:IGI+ and Transform
  • Increased the limited on the number of shapefile that can be added to Maps. Users can now add a maximum of 20, but the user is reminded that large numbers of shapefiles will impact the performance of pan-zoom on the map
  • Samples can be selected for brushing from pages using a right-click option or keyboard shortcut Ctrl+B on an active page (Ctrl+Shift+B clears the selection of single samples) styling of brushed and selected points has been enhanced to show selection alongside all other stylings
  • Ctrl+L works to clear the whole brushed set across all contexts, not just graphs
  • Users can link to external resources (described using a URI – web pages, web links, file paths) from pages and visual query. Users can quickly launch dynamic links to open the resource in whatever viewer is registered for this on their system. Add a text link like https://www.igiltd.com/ or D:\Data\Chromatograms\XYZ1234a.png to a text cell and this becomes navigable if the link resolves to a resource on your computer
  • Updated the right click menus on pages to reduce clutter. Put page configuration actions on the page’s property header right click menu, and sample manipulation / data actions on the data grid right click menu
  • Improved the treatment of properties IGI has deleted from the property model. On pages, the page can be opened, and the deleted property is automatically removed from the list of properties shown.
  • Added many symbols to the shape palette to provide the user with 100 distinct shapes.
  • Editing of discrete palettes has been improved, allowing the user, when in the edit palette assignment dialogue, to sort the palette entries alphabetically, or on frequency of occurrence
  • The Import data route has been heavily revised, to improve the robustness and performance of the autodetection, and improve the flexibility of what can be imported
  • The use of aliases in the property search has been enhanced to make it simpler to find properties based on their aliases
  • The import well data route has been revised, adding autodetection of incoming well file structure to determine the well information being imported (p:IGI+ well file, stratigraphy, well information from Excel etc.)
  • Well names are now case sensitive across the software
  • For dynamic sample sets a descriptive Expression Summary has been add to the create dialogue. This is automatically generated as the associated query string is built up
  • Removed the ‘out of range’ data shortcut icon from the toolbar (as it was previously unclear whether the feature had been toggled on or off). Operation of the out-of-range feature now sits on the Page menu with options to turn it on or off
  • Added an application help dialogue with information about where to get support – linking to the online user guide, and providing the support email. This is location on the Help Menu
  • Added several new autographs
  • Various graph name, plot title, and axis title edits made across existing autographs

p:IGI+ specific features

  • PCA has been updated to make it a full artefact, allowing retraining and providing improved sharing between projects
  • Clustering has been added – the first version provides k-means clustering

Metis Transform specific features

  • As well as the general improved performance and scalability, the scalability of upload to Staging has increased, allowing more efficient updating of data.

Metis Discover specific features

  • Query performance has been significantly improved
  • Introduced several new types of criteria that can be used to query data
  • Queries can now be bookmarked and saved for later use. They can also be shared with colleagues, edited, and removed
  • Wellbore viewer. Each wellbore returned by a query can be viewed in detail.
  • Export performance has been significantly improved. Users can now export up to 40,000 samples
  • As well as exporting data by analysis groups, data can also be exported by properties. Up to 20 properties can be selected to export a subset of the data
  • Discover can be integrated with an ArcGIS or Web Map Service (WMS) to show layers on the map. Layers are configured at a server level, as a result they are visible to anyone who has access to the environment. IGI are happy to provide support to configure this feature
  • Metis now captures queries and exports performed by users in an activity log. The activity log is only viewable by data mangers within an organisation. The who, what and when of each query or export, along with the time taken, is recorded

Property model changes

  • Added a series of mode, min & max VR equivalent reflectance properties to the MatCalc property group
  • The interpretation aspect of the property model has been completely overhauled
  • Added a rig name property to the well property group
  • Added sample temperature (Sam Temp) to the physical analysis group
  • Added the reservoir mode properties S2a and S2b properties to the PyrolHawk & Extr analysis group
  • Added specific bulk and extracted TOC.Any properties (TOC_Bulk & TOC_Extr) and updated relevant pyrolysis equations to use the appropriate .Any property as an alternative to the analysis specific TOC property as a fallback
  • The Pol-GCMS analysis group has been expanded to include ethyl- & dimethyl-carbazoles, Fluorenone & methyl- equivalents and Xanthone & methyl- equivalents
  • Deleted several duplicate properties in the model, with a migration of the data to an appropriate property. Data is preserved in the target property if that is already populated
  • A series of Alkylbenzene ratios, 1-12, added to the WO-GC and Py-GC analysis groups
  • Extended the range properties measured from the m/z 183 ion trace in the Sat-GCMS analysis group
  • Added a series of Alkylcyclohexanes (13-34) from the default 83 and alternative 82 ion channel trace, with associated n-Alkylcyclohexane CPI equation properties
  • Extended the range of Alkybenzenes in the Arom-GCMS and WO-GCMS analysis groups up to 34ABenz
  • The sequence and biostratigraphy properties in the Geol property group have been redefined to be reported properties, capturing values reported alongside the sample
  • Source properties have also been added to record where the sequence and biostrat values came from


  • The software will now work on high resolution 4K displays, at all font scaling sizes
  • When creating project properties the equations are now shown using the correct display names for properties
  • Users can no longer harmonise on well name – this never worked correctly – instead users should delete incorrectly named wells and assign the samples to the correct well(s). Users are advised of this, but can still access the list of distinct well names provided in the harmonise dialogue
  • It is possible to edit the long name for project properties without changing the short name
  • Auto-import is more robust, having improved the auto-detection of the column separator
  • The definition, and interaction with numerical palette bins has been improved, with clearer feedback to users
  • Fixed an issue where it was possible to crash p:IGI+ by resizing a graph to be too small. Also made the resizing of graph windows more responsive, and improved the speed of interaction with graphs slightly
  • Fixed a map visual query bug that left a site looking selected when it was not even brushed
  • Fixed the positioning of axes ticks / grid lines on the multi-depth plots
  • Fixed clipping of ticks on inverted graph axes
  • Fixed an issue with the display of formation tops on depth plots, where tops could be drawn at the wrong depths with a very specific combination of different datums being used
  • Added a scroll bar to visual query to prevent the window becoming unusable if too many properties were added

Known issues

  • It is not possible to migrate .pigi projects to .pigi2 projects on network drives. Please update projects on a local drive. This will also be more performant.
  • It is not possible to use the project merge in Metis Transform using date-time properties if there are missing values for those properties – this is being addressed and will be fixed in the next release.
  • The “Sitka” font family does not work when copying graphs – it displays fine, but the graphs will not copy correctly. We advise users to not use this font family, which has some known issues in Windows
  • When a lot of graphs are open at the same time, or after long use of p:IGI+ sometimes you get no points shown on a graph, and a text error message saying “E_OUTOFMEMORY: Ran out of memory (****)”. To address this save the project, close p:IGI+, restart, and open the project. We are still exploring the issue
  • Occasionally when resizing graph windows the data view can pan unexpectedly. This is a rare event, and we have not yet been able to isolate a fix. If the original zoom extent is saved, then the user can recover to the desired view by opening graph manager (Ctrl+G) and selecting to restore the zoom

Installation issues

  • Requires .NET framework version 4.8
  • Projects will be migrated from earlier version to .pigi2 / .metis2 files. This can take time for large projects
  • Requires DirectX 9 for the graphs to work

It is possible some files will have problems when migrating. In this case we suggest you send these files to support@igiltd.com and we will investigate and fix any issues.
