4.0 How to mention a file

How to Trigger the @ Pop-up

1. In the chat input bar, type @

2. A file picker pop-up appears immediately

3. Start typing a filename to filter the list in real time

4. Click or press Enter to select the file

Usage Examples

• Reference a data file: expression_matrix.csv load this and show column names and shape

• Ask about a figure: figure1.png what does this plot show and are there any issues?

• Continue from a previous script: analysis.py add a step to normalize the data after line 12

• Summarize a paper: paper.pdf summarize the methods and list the key findings

• Inspect the notebook: note.ipynb what analysis has been done so far in this session?

• Filtering in the Pop-up

• As you type after @, the list filters by filename:

You can type partial names — the search matches anywhere in the filename, not just the start.

Key Rules

• Files must be uploaded or already in your workspace to appear in the @ pop-up

• Files in /home/user/ (outside user_data/) only appear within the current session

• Files in /home/user/user_data/ appear across all sessions in that project

• You can mention multiple files in one prompt: @metadata.csv and @counts.csv — merge these on the sample_id column
