September Update BUILD 20201002 02/10/2020
Gorilla Roadmap
This month marks the first of our Gorilla Roadmap releases. Features suggested by Gorilla Users, for Gorilla Users!
Task Builder: Audio recording filenames
Audio Recording files (as well as Video Recording, Mouse Tracking and Eye Tracking files) are now labelled with the participants Private ID.
Task Builder: Upload many spreadsheet with one file
Using a single .xlsx file, upload multiple spreadsheets to Gorilla. The sheet name in the file is used as the Spreadsheet name in Gorilla.
Questionnaire widgets can now be expanded/collapsed to facilitate easier construction of very large questionnaires.
Data: Include manipulations in metrics
Manipulations will now appear in the data download for each Task node.
Gorilla: Informative page titles
Window/Tab titles will now reflect the content of the page.
New Features
Task Builder: Reading Zone
Allow manual setting of font size in the reading zone.
Task Builder: Localisation
The text content of all Task Builder zones, including many error messages, can now be edited, allowing fuller localisation of Tasks.
Task Builder: Post-task uploading screen
When uploading task metrics and additional files at the end of task, Gorilla now presents an uploading screen. This is to prevent participants from thinking the page has crashed, by keeping them informed during loading stages.
Task Builder: Improved client side error logging
Increased usage of and improved quality of data returned by client side error reports. This will help us in resolving some rarer, harder to diagnose issues.
Task Builder: 'Download to Disk' option for Audio Recording zone
To facilitate collection of larger audio files, allow files to be downloaded to the participants harddrive and uploaded separatly via a third party. This allows for audio files longer than 2 mins to be collection. Make sure you set up the third party uploading and provide suitable instructions for the participants on how to use it.
Fixes & Enhancements
Data Generation: Fixed issues where individual files and zip folders would fail to build! Huzzah!
Task Builder: Resolved issue where Reading Zone mask would spill into other lines.
Task Builder: Improved layout of Calibration zone content, to better fit smaller screen sizes.
Task Builder: Improved performance of Progress Bar when using large spreadsheets.
Task Builder: Improved performance of image rescaling when using the Screen Calibration zone.
Task Builder: Resolved issue where populating the Web Audio zone via Embedded Data would work incorrectly.
Task Builder: Resolved issue where populating the Video zone via Embedded Data would cause a 'Video missing error to appear'.
Questionnaire Builder: Fixed incorrect response indexing text for Checklist widget.
Questionnaire Builder: Fixed bug where Questionnaire builder would detect duplicate keys incorrectly, preventing changes from being committed.
Known issues
Task Builder: Stimuli loading and data uploading screens can't be localised. This will be resolved in a future update to Gorilla.

Experiment Error Checking
We've enhanced the error checking for experiment trees, and now run it automatically when you commit, to prevent you from using a broken tree design. The new tool detects orphaned nodes, dead ends, branch nodes with no default branch and layouts which would cycle indefinitely.
Restore To Previous Version
You can now restore a previous version of a task, questionnaire or experiment to be the current version
All Participants have a PublicID
All participants now have an autogenerated PublicID, if one hasn't been specified in advance. This prevents situations in unblinded experiments where participants cannot be identified in downloaded data as they have a blank PublicID
Save Task Builder Response As Embedded Data

In the Task Builder, moved Go To setting to own zone, rather than always being present on the screen
Added multiple enhancements to Bulk Subscription Management tools
Fixed issue in Task Builder tasks where use of Time Limit Section could break the Trial Number counting
August Update BUILD 20170809 09/08/2017
New Features
Pay-per-participant
New pricing model that allows you to pay a small fee per participant. All existing users on Free accounts are now on Pay-per-participant accounts. All existing users on Code or Pro accounts are now on Unlimited accounts, which allow them to run an unlimited number of participants.
Recruitment Targets
You can now set a recruitment target for your experiment, and Gorilla will automatically stop accepting new participants once the target has been reached. Users on Unlimited accounts can still set their recruitment target to Unlimited, which will continue to accept participants until it is disabled.
Reject Nodes
You can now use Reject nodes in place of Finish nodes for situations where a participant should be rejected rather then continuing with the experiment. These can be used to screen out participants who don't meet your recruitment criteria. Rejected participants don't count towards your recruitment total.
New collaboration rules
You can now assign the ability to make changes to your experimental designs and the ability to download participant data separately. This means you can add collaborators who can make changes but cannot download data, or alternatively add collaborators who can download data but can't make changes to your experiments.
All projects now have an Owner, and anyone else on a project is now a Collaborator. Existing collaborators who had read/write or admin access have been set to be able to make changes and download data, and those with read access only continue to only have read access.
Fixes & Enhancements
Pay-per-participant account tier now has access to the Code Editor
New pricing offers both academic and commercial rates

New Features
Background Report Generation
Experiment data generation is now done in the background, meaning that large reports can be built without requests timing out.
Small reports should be ready for download within a few seconds. For larger reports, you can request to be emailed when the report is ready. Once generated, a report can be downloaded by you and your collaborators.
Task Builder Branching
Screens in the Task Builder can now be set to advance to a named screen in the same display, rather than always advancing to the next screen.
Screens which have a correct answer set can advance to a different screen depending if the response was correct or incorrect.
Task Builder Progress Bar
There is a new Task Builder widget for displaying a progress bar, to show your participants how far through the task they are
Click Painting
There is a new Task Builder widget for capturing spatial input, where your participants are shown an image and can click anywhere on it. The coordinates of where they clicked are then recorded as part of the response.
Audio Feedback
There is a new Task Builder widget for playing audio feedback, depending on whether the participant's response was correct or incorrect.
Time Limit
There is a new Task Builder widget called Time Limit, which replaces the existing Auto Advance functionality and adds the ability to show the number of seconds remaining.
Existing Auto Advance settings will still work, but new tasks should use Time Limit instead.
You can elect not to show the remaining time, which makes the new Time Limit behave identically to the old Auto Advance.
Custom Feedback Images
Feedback (Accuracy) zones can now be given custom images to display, instead of the default green tick and red cross.
Feedback Honesty
You can now give Feedback (Accuracy) zones a percentage chance to give dishonest feedback. You can use this to implement probabalistic learning paradigms.
Checkpoint Node
There is a new Experiment Tree node called Checkpoint, which updates the participant's status to show the most recent checkpoint they passed through. The most recent checkpoint is shown on the Participants screen, and all checkpoints passed will be come through in metrics data.
Fixes
Added ability in Task Builder for Likert inputs to be one-click-only (thus making them an active response)
Added ability in My Account screen to disable emails for particular channels
Tree Node key is now shown on the experiment tree
Changed name of Response Paragraph (Text) and Response Paragraph (Rich Text) to Response Button Paragraph (Text) and Response Button Paragraph (Rich Text) respectively

Added ability in Task Builder for Go/NoGo widgets to have an additional image to use for the wait time, rather than a fixation
Fixed issues where updating all nodes in a tree to a new version didn't work correctly
Fixed issue in Task Builder where passive responses didn't store embedded data correctly
Fixed some issues around uploading a new version of a stimuli asset that had previously been deleted
Fixed issue where search text in Code Editor was white (and so invisible)
