# Version 1.13.1

Release date: 16.04.2021

# Highlights

This release adds a single bufix.

# All changes

  • Fixed a bug causing excessive load on backend

# Version 1.13

Release date: 09.04.2021

# Highlights

This release brings several improvements to variant filtering rules, as well as a number of smaller fixes.

# Improvements to variant filters in ELLA

It is now possible to configure the Classification filter to only consider classifications that are still valid. With this option enabled it is possible to define that e.g. class 1 and class 2 variants should be filtered only if they have a classification that is still valid (not outdated).

# Improvements to pre-filters

The pre-filters (applied before import of variants into ELLA) are now configurable and has the added option of pre-filtering variants with low mapping quality (MQ<20). This latter option is relevant e.g. for variants called with Dragen-GATK, which unlike GATK does not automatically exclude variants with a low MQ.

# Upgraded IGV in VISUAL

IGV.js on the VISUAL page has been upgraded to v2.7.9 (opens new window). For ELLA users, this fixes a few bugs, but also brings new view mode options: Click the cog wheel to the right of a track to switch between "expand" (default), "squish" or "collapse" display modes (available options depend on track type).

# Breaking changes

With the improvements to pre-filters, the configuration in usergroups.json must be updated. The equivalent to the previous "prefilter" = True is now "prefilter": [["hi_frequency", "no_nearby_variant", "no_classification", "not_multiallelic"]]. See pre-filters for further details.

# All changes

# All changes

  • Fixed a bug causing ELLA not to start.
  • Fixed a bug causing excessive memory use in exports of variant interpretation database.
  • Fixed an error in test configuration.

# Version 1.12.1

Release date: 19.01.2021

# Highlights

This release adds a few bugfixes.

# All changes

  • Fixed a bug that caused pre- and postprocessing to fail.
  • Fixed a bug that caused missing "Requested" date on imported analyses.
  • Fixed a bug that caused performance problems.

# Version 1.12

Release date: 13.01.2021

# Highlights

This release includes many fixes and improvements, both to the frontend and backend/development environment. The most significant changes for users include changes to classification, history and variant warnings:

# Redefined classification choices

Variant classification choices have been redefined in line with ClinVar definitions (opens new window):

  • CLASS U was renamed to NOT PROVIDED, meant for recording various information (literature/research/clinical/phenotyping) without interpreting clinical significance. It is recommended to configure this class to be immediately outdated.
  • The choice RISK FACTOR was added, meant for variants that are interpreted not to cause a disorder but to increase the risk.

The classification choices are now:

# Improvements to history

History for changes to the variant CLASSIFICATION REPORT field was added, and the HISTORY pop-up now shows a drop-down for viewing previous versions instead of listing them:

In addition, when opening a previously finalized analysis, ELLA will now default to displaying the state corresponding to the latest interpretation round, i.e. showing variant interpretations, classifications and annotation exactly as they were presented at the time of the last finalization. The previous default, CURRENT DATA (along with any other interpretation round), is still available using the drop-down in the top bar. To prevent confusion, a warning was added when viewing historical data.

# Improved warnings

To improve visibility of the different variant warnings displayed on the CLASSIFICATION page, collision warnings are now shown in a yellow banner separate from annotation and user group warnings (red), and collision warnings are no longer included in the ! tag in the sidebar:

Figure: Collision and annotation warnings are now separate.

In addition, ELLA now displays a message at the bottom of the page if a finalized variant in an ongoing analysis has been updated and finalized by another user:

Note that the message is only displayed when a user finalizes another variant or manually refreshes the view.

# Select user group on custom imports

To better support custom gene panel imports that should be available to more than one user group, the custom gene panel import dialogue now includes an option to select user groups:
