There have been lots of recent changes to the Rock Mass Data Analyser. Some of these changes just add features, but as part of these changes we have had to re-organise how the data is structured in the app. This means that the individual databases for all of the data now come in as aliases in the root folder under Settings/#Site Setup/RMDA/Inputs folder (instead of places such as Rock Mass Characterisation/RMDA/Database/2 Rock Mass Quality).

We are excited to announce our new inspections and data entry app. This app is a general purpose data entry app designed for offline use with tablet devices which can be customised to fit each site's exact needs.

There has been some rearrangement to the ! folder within the root folder, which may affect some of your apps. This was primarily a move of tools which are not seismic specific from the ! folder to !/Base (so that mines without the seismic suite can use these tools). The most commonly used parts of this migration are anything that uses Filter Volumes, Grid definitions or Plane definitions.

There have been a number of recent updates to the Short-term Response Analysis app. These include:

• Chart for determining re-entry using different parameters: This chart gives you values for a particular parameter over time (based on a user-defined time window size and step). A threshold value for that parameter can be set, allowing you to see when the seismic data drops below that threshold. The parameter investigated can currently be set to energy, event count, hazard, background ratio and activity rate probability. For more information about these parameters, see Tierney et al. 2019.

If you use Datamine at your site, we now have a tool to help you batch convert the datamine TR and PT files into mXrap-readable dxf files.

The Large Event Analysis app has receieved a number of upgrades recently. These upgrades focus on analysing seismicity in the immediate time before/after a large event. A new window, called 'plane based analysis', allows the user to investigate the source parameters around the location of an event before/after it occurred.

There are a number of updates to the Grid Based Analysis app. The first is the ability to use multiple planes for analysis instead of just a single plane.

CheX is mXrap's new system for setup and support. It is a checklist-based website which helps users to follow step-by-step instructions to complete tasks such as setting up a root folder, applying a patch and doing a default backup.
