First Workflow

This is the best first exercise for new users.

1. Open an archive

• open a .ar or .fits file from the sidebar, the menu, or drag and drop
• PSRUI creates a backend session for the active file
• profile, waterfall, time-phase, and bandpass previews are fetched from the session preview in parallel

2. Read the basic charts

• Profile: confirm the pulse shape looks sensible
• Freq x Phase: look for frequency-dependent RFI or structure changes
• Time x Phase: check stability across sub-integrations
• Bandpass: inspect unusual channel averages

3. Open the Processing Inspector

Use the Processing button in the chart toolbar.

Recommended order:

• start with Zap for channel-level RFI excision
• continue with Pam for dedisperse, tscrunch, and fscrunch
• move to TOA only when you already know which template you want

4. Export results

• Save Archive always writes a new processed file
• Batch lets you save the current recipe and reuse it across many files

PSRUI today: session previews are non-destructive. Only export operations write new files.
