Sync your experiment trials to a linked Foundry dataset with one click, writing a snapshot of all trial data as a Parquet file.

---

What's included​

Sync button on the trials page​

A new Sync button sits in the top-right toolbar of the experiment trials page, next to the Add and Upload controls.

• Click Sync to export all trials for the experiment to the linked Foundry dataset
• The button shows a loading spinner while the sync runs and toasts the number of rows synced on completion
• The button is disabled when there are no trials or no Foundry dataset is linked to the experiment

What gets synced​

• Only trials where all parameters are complete are included, regardless of state
• Each sync overwrites the previous snapshot

---

Notes​

• The Sync button requires a Foundry dataset to be linked to the experiment at creation time
• Each sync is a full snapshot — incremental/append writes are not currently supported

Save and reapply chart configurations across Plot Builder and Correlation analysis. Build up a view by adding chart settings one tab at a time, then share a link to reproduce the exact setup.

---

What's included​

Views menu​

Use the Views button in the study toolbar to save, apply, and manage your chart configurations.

Save chart configurations as views​

• Use Save as new view… to create a named view from your current chart configuration
• Saved views are stored per study and can be selected, applied, and deleted at any time
• Applying a view restores your axis selections, colour, symbol, and trellis encodings in Plot Builder, and your column and colour selections across all Correlation tabs

Build up a view across multiple charts​

• Each chart page (Plot Builder, Correlation Matrix, Correlation Ranked, Correlation Pair Plot) contributes its own configuration slot to a view
• Use Save to "[view name]" to add or update the current page's settings into the active view without overwriting the other slots
• Navigate between charts and keep saving to build up a view that spans multiple chart types

Share a view​

• When a view is active, the URL contains a ?view= parameter — copy and share it to let a colleague open the same configuration directly
• Views are study-scoped, so the recipient must have access to the study

---

Notes​

• Correlation tab settings (columns, colour) are saved independently per tab type, so Matrix, Ranked, and Pair Plot each have their own slot within a view
• Clearing a view (the × button next to the Views menu) returns each chart to its default state; it does not delete the saved view
• Views currently work for Plot Builder and Correlation only — support for PCA, Survival, and other chart types is coming soon
• This is an incremental update during beta

Catalyst Assist can now answer questions about the data in your study — counts, averages, distributions, and filtered breakdowns — by querying the dataset directly.

---

What's included​

• Ask data questions in natural language — "average overlay error by tool?", "how many wafers failed process control?", "distribution of risk score by lot" — and Assist queries your study dataset to answer
• Answers are computed from your actual data, returned as markdown tables, with a brief takeaway drawn from the results
• Date and duration math is supported — group by year, compare timestamps, measure elapsed time between events
• Platform and feature questions still work exactly as before — Assist picks the right mode for each question

---

Notes​

• Data answers come only from your dataset — Assist never invents, estimates, or extrapolates figures
• Data questions are available when Assist is opened from within a study
• Data queries run on the study's worker, so it must be provisioned and active; otherwise Assist still answers platform and feature questions but can't query the dataset
• AI responses may not always be accurate. If you receive an unexpected result, let us know with the thumbs up/down on the response, or share it via Support → Contact Support
• This is an incremental update during beta

The folder picker is now easier to navigate, supports deeper search drill-down, and lets you create folders in the right place.

---

What’s included​

Easier folder navigation​

• You can now drill into folders directly from search results instead of starting over in the main tree
• Search breadcrumbs stay clickable, so it’s easier to move back up when you’ve drilled in
• Search results only show folders you can actually use, so there’s less dead-end clicking

Folder creation in the right place​

• The picker follows the same folder structure used in Foundry: space -> project -> folders
• A space is like a shared drive, and its first-level listings are project resources
• Admins manage projects, so you can browse into them but cannot create new folders at the project level itself
• You can create folders once you’re inside the folders within a project, including after drilling in from search

---

Notes​

• Folder creation is only available once you’ve drilled into a valid folder location inside a project
• If a folder does not appear in search, you may not have permission to use it

Ask questions about Catalyst and get instant, documentation-backed answers — right from the sidebar.

---

What's included​

• Click Assist in the sidebar to open the panel from any page
• Ask a question and receive a focused, markdown-formatted answer grounded in Catalyst documentation
• Source excerpts are shown beneath each reply so you can verify or explore further
• Follow-up questions are supported — prior context is carried forward within the same conversation
• Use the + button to start a new conversation at any time

---

Notes​

• Answers are based solely on Catalyst documentation — the assistant will not speculate or invent features
• AI responses may not always be accurate. When in doubt, refer to the official documentation for authoritative guidance
• If you receive an unexpected or unhelpful response, please share it via Support → Contact Support
• Conversations are limited to 20 messages; start a new one for unrelated topics

Create PCA clusters from sigma bands and compare only clusters that contain points.

---

What's included​

Create clusters from sigma bands​

• Open the cluster menu in PCA -> Cluster Analysis to create ready-made Inside nσ and Outside nσ clusters without drawing a brush
• Sigma-based clusters automatically assign matching points as soon as the PCA view finishes loading
• The matching sigma contour adopts the cluster color so you can see the selected boundary at a glance

---

Compare populated clusters only​

• Cluster comparison menus now show only clusters that currently contain points
• If a selected cluster becomes empty or is removed, the comparison updates to the next valid populated cluster automatically

---

Notes​

• Sigma-based clusters are stored with your other PCA cluster selections for that study
• Outside nσ options are available for every displayed sigma band, while Inside nσ options are available for the inner bands
• Empty clusters are excluded from comparison choices until they contain points

Send feedback, bug reports, and feature requests directly from the Support menu.

---

What's included​

Contact Support from anywhere​

• Open Support -> Contact Support from the app sidebar without leaving your current page
• Submit one of three request types: General Feedback, Bug Report, or Feature Request

---

Faster issue triage​

• Add a clear title and detailed description so the team can understand your request faster
• Your submission includes your current page, browser, and account details to reduce back-and-forth

---

Notes​

• The form requires both a title and description before you can submit
• Messages are limited to 1,500 characters
• For bug reports, include steps to reproduce and what you expected to happen

Excluded columns are now hidden by default in the Data Health summary, and both the Data Health and Column Settings pages show a consistent "Hide excluded (N)" filter.

---

What's included​

Standardized "Exclude" action​

The action previously labeled Drop column in the Data Health table is now labeled Exclude, consistent with the terminology used in Column Settings. Excluded columns (visibility offs) are now hidden by default in the Data Health summary table. A Hide excluded (N) checkbox appears in the toolbar whenever there are excluded columns, allowing you to reveal them when needed.

Consistent filter in Column Settings​

The same Hide excluded (N) checkbox — showing the count of excluded columns — is now displayed in the Column Settings page, matching the behaviour in Data Health.

---

Notes​

• Excluded columns are hidden, not deleted — your underlying data remains unchanged
• The count in the checkbox reflects how many columns currently have visibility turned off
• If you notice any unexpected behavior, please share steps to reproduce

Instantly understand any plot with an AI-generated summary — powered by an LLM with vision.

---

What's included​

How it works​

• Click the AI Summary button in the Plot Builder toolbar
• A vision-enabled LLM reads the plot statistics and sees the chart, then returns bullet points covering distributions, group breakdowns, data quality issues, and visual patterns like clusters or outliers
• Hit copy to paste the summary into a report or analysis note

---

Notes​

• Works with scatter plots, box plots, and heatmaps
• The summary is factual only — the LLM does not assess or make recommendations
• If you notice any unexpected behavior, please share steps to reproduce

Rename and include or exclude columns across your study from Column Management.

---

What's included​

Column Management​

You can now manage columns from Edit → Columns.

• Exclude columns to remove them from all views in the study — including plots, statistics, and column groups
• Include columns again at any time to restore them across the study

---

Update Column​

• Rename columns to use more meaningful display names across your study
• Changes are applied consistently across all views

---

Notes​

• Excluded columns are hidden, not deleted — your underlying data remains unchanged
• Renaming affects display only and does not modify raw data
• If you notice any unexpected behavior, please share steps to reproduce
