One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
I have a figure with three panels (micrograph, bar chart, line plot). Should I upload each panel as an individual image file during the submission process, or combine them beforehand?
| Checked | Without skill | With skill |
|---|---|---|
| The response instructs that multi-panel figures must be assembled into a single composite image file before upload. | Passed | Passed |
| The response prohibits uploading individual panel files separately. | Missed | Passed |

This guide provides the complete specifications for preparing figures for submission to Nature and Nature Research journals. Following these guidelines ensures smooth processing and high-quality reproduction of your figures in both print and online formats.

| Image Type | Minimum Resolution | Notes |
|---|---|---|
| All figures | 300 DPI | At maximum print size |
| Optimal quality | 450 DPI+ | Recommended for best online display |
| Online submission | 300 PPI max | To keep file sizes manageable |
CRITICAL: Do NOT artificially increase resolution (upsampling) in image editing software. This does not improve quality and may introduce artifacts.
